Fort Lauderdale, FL – Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing 8 brand new  Honeywell RA890F Electromechanical Relay Modules. The RA890F Protectorelay Primary Control is a nonprogramming, amplifying relay that provides solid state electronic flame safeguard protection for industrial and commercial gas, oil, or combination gas-oil burners.

The flame current check is the best indicator of proper flame detector application. Perform the check at the time of installation, at any time service is done on the system, and at least once a month or more often while the system is in operation. This prevents shutdowns due to poor flame signal. Perform test by connecting a W136 (or equivalent) microammeter in series with the flame detector and reading the flame signal while the burner is operating. Insert a 196146 Meter Connector Plug, wired color-tocolor to the W136A leadwires, into the test jack on the RA890F. This automatically puts the microammeter in series with the flame detector. If a meter connector plug is not available, disconnect the flame detector lead from the F terminal; then connect this lead to the Black lead of the microammeter, and connect the Red lead of the microammeter to the F terminal. When reading the flame current, assure the following criteria are met: 1. The flame current is steady; meter does not vary more than a needle width. 2. The flame current is at least two microamperes for a rectification type detector like used with the RA890F. The normal operating range is 2 to 5 microamperes.

Features:

- Uses rectification principle of electronic flame detection.

- Replaces RA890E in most applications and mounts on same Q270A1024 Subbase.

- Recycles if flame signal lost while in Run. Failure to establish pilot results in a lockout.

- Safe-start check prevents start-up if flame-simulating failure occurs in flame detector circuit.

- Includes built-in protection against ignition crossover in flame rod systems.

- Includes SPDT alarm contacts.

- Solid state circuitry.

- Mounts and removes easily through use of captive mounting screws.

- Mounting base is made of strong thermoplastic.

Specifications:

- Install the RA890F where the surrounding temperatures remain within the Ambient Operating Temperature Ratings listed in the SPECIFICATIONS section.

- Install the RA890F where the relative humidity never reaches the saturation point. Condensation of moisture on the RA890F may cause enough leakage to short the flame signal to ground and prevent the burner from starting.

- Do not install the RA890F where it could be subject to excessive vibration. Vibration shortens the life of the electronic and mechanical components.

- The RA890F is not designed to be weathertight. If it is installed outdoors, use a suitable weathertight enclosure.

- Locate the subbase where ambient temperature is within the specified rating.

- Mount the subbase so the top and bottom are horizontal and the back is vertical. The subbase can lean backward as much as 45 degrees when necessary.

- When an RA890F replaces an RA890E, there may be installations where ignition interference is not sufficient to destroy the RA890E, but is sufficient to prevent operation of the RA890F due to its arc gap protection.

- UL Listed: 120V models only; File No. MP268, Guide No. MCCZ

- Approved: Report No. 17678,19417,19784

Models available:

1. RA890F1270

2. RA890F1288

3. RA890F1296

Fort Lauderdale, FL – Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing 10 brand new Honeywell Signal Processors. Honeywell has a wide array of discriminating flame monitoring systems for industrial and difficult flame detection applications. Honeywell has teamed with IRIS Systems to distribute industrial flame detection systems. Tailor made for the unique demands of industrial processes, the CS550B dual UV/IR viewing head delivers flame discrimination in the toughest environments. With automatic setup, three channels and the ability to monitor UV and IR flame components simultaneously or separately, the RP532 signal processor offers improved burner up time and reliability. Honeywell industrial flame monitoring by IRIS Systems provides the perfect blend of form, function and flame detection.

Flexible Programming:

- Three methods of viewing head programming offer user flexibility; automatic, manual or factory defaults. Signal processors have keypads (model dependent) or may be connected to FlameTools software. Each viewing head has independent configuration. Certain models allow two sets of configuration data per viewing head. The RP531 processor has an available detachable programming plate, which reduces cost on large installations. With the plate, the RP531 has the same functionality of the RP532 processor.

X-Ray and Gamma Ray Immune:

- All viewing heads are immune to X-Rays and Gamma rays, making them ideal for myriad industrial applications.

Flexible Application:

- Wide array of products to meet broad industry needs

- Signal processors available in AC or DC versions

- Universal AC power inputs: 85-265VAC, 50/60Hz

- Independent configuration for each sensor

- FM and CSA approved

- Hazardous location viewing head models: Class 1, Div 2, Groups A, B, C & D, T5 and T4A

- Proportional 0/4-20mA flame signal output

- Flame and self-check relays

- Viewing head adjustable UV and IR gain settings

- Viewing head temperature indication

- Multiple high pass IR flicker frequency settings

- Electronic shutter for viewing head self-check

- Quick disconnect cable connection included

- Compact UV and IR detectors perfect for pilot monitoring

- UV Flare stack application specific model

Dual UV/IR Viewing Heads:

- Dual UV and IR sensing capabilities are housed within the same detector to provide application flexibility. Their ability to discriminate between all types of fuels, the main flame and unwanted background, make them uniquely suited for multiple industrial processes. Monitor UV and IR simultaneously or separately with the RP532 signal processors.

Individual UV and IR Viewing Heads:

- Multiple housing sizes and gain settings in both UV and IR to fit your application. Perfect for single and multiple burner applications and pilot monitoring.

Key Application Attributes:

- Lifecycle Costs: Separate signal processor and viewing head for ease of maintenance

- Set-Up:

> Wide spectral response for a variety of difficult to site applications

> Adjustable “Flame On” and “Flame Off” points for added discrimination

> Digital processing means you work with numbers – reduced field set-up time

> Ability to set-up and store settings in memory for ease of replacement

> Wide gain adjustment and multiple flicker frequency setting capability to prevent flame out in single or multiple burner applications

Burner Management System Interface:

- Each signal processor has a 0/4-20mA scalable flame signal output, two SPDT or SPST flame relays, and one SPDT or SPST self-check relay. The RP532 and RP531 signal processors also have a 24VDC auxiliary output and three N.O. alarm relays. Signal processors may also be linked to BMS using Modbus RTU protocol for monitoring and diagnostics.

Remote Configuration, Monitoring, Diagnostics:

- Easily interface multiple signal processors through FlameTools software for remote configuration, monitoring and diagnostics. Each signal processor is Modbus RTU capable with selectable parity and baud rate settings. Link up to 31or 63 signal processors (model dependent), in a single daisy chain loop, to FlameTools software. Refer to the applicable manual for connection method (RJ-11, RJ-45, 2-wire twisted pair, stereo jack).
