1.0 Description

The product is a cost effective "smart" transmitter that accepts resistance signals including RTD sensors and converts them to a standard industrial
(4 to 20) mA transmission signal over a user programmed range.

PC configuration allows the user to select Sensor Type, Range, Units and Error Signal without requiring calibration equipment. Configuration is
performed quickly using our new USB port driven configurator by simply connecting to the units loop and following the software instructions.
Configuration set up may be saved as a file on the PC for later use. Additionally, the user may read live process data when connected to the PC,
allowing for sensor calibration, where the user can enter an offset value to correct any sensor deviation.

2.0 Important safety Information

To maintain CE compliance all input wires must be less than 3 metres.The product contains no user serviceable parts, or internal adjustments.
No attempt should be made to repair this device. Faulty units must be returned to supplier or manufacturer for repair or replacement. This product
must be installed by competent qualified personnel. All electrical wiring must be installed to comply with the area standards, regulations.
Before attempting electrical connection ensure all supplies are switched off.

ABSOLUTE MAXIMUM OPERATING CONDITIONS :-

Supply 30 V dc ( reverse protected to -30 V dc)

Supply Current on over voltage + 100 mA (when supply exceeds 30 V dc protection the device will conduct)

Ambient -40 to + 85 °C

3.0 Mechanical Details

The unit must be installed with adequate protection from
corrosive atmospheres. The correct type of M12 mating
connectors should be used to maintain IP67 protection.

F
purchased as part of a probe assembly steps (1 to 3 ) will have been completed. The user can re-configure the transmitter range on a completed

2. Probe assembly

Omega offers two styles of RTD probe assemblies that will connect directly to the sensor input. Please refer to date sheets
for PR-21 and PR-22 probes.

3. Wire sensor

Sensor connections are made by the use of a suitable M12 plug (Omega part No M12-S-M-FM). All sensor connections must be isolated from
ground. To maintain BS EN61326 compliance sensor wires must be less than 3 metres.

4. Install assembly

Care must be taken as to where the unit is located, so that the ambient temperature of the transmitter does not exceed the specified operating
temperature of (-40 to + 85) °C.

5. Wire (4 to 20) mA Loop

A suitable M12 socket is required for output connection
(Omega part No. M12-R-F-FM). To comply with CE regulations the (4 to 20) mA
loop must be earthed at one point, normally at the power supply. The loop load
symbol represents other equipment in the loop such as an indicator, controller
or signal conditioner.
