CMCP-580 Process Variable Transmitter

CMCP-580 Process Variable Transmitter

Features:

  • Low Cost

  • Small Size

  • DIN Rail Mount

  • 4-20 mA Output

  • Fault Detection

  • Buffered Transducer Output

Approved


Description:
 The CMCP-580 Process Variable Transmitters are compatible with several types of DC voltage and current inputs, they provide a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the signal, and outputs a 4-20 mA dc current that is proportional to a user specified range such as 0-100%. Combining transmitters with an existing PLC or DCS system results in a high density, low cost monitoring system. When specified with the alarm feature (CMCP-580A), the unit functions as a complete single channel monitor that includes alert and danger alarms, and output relays.

 

Buffered Output:
 A BNC connector mounted on the front of the unit provides access to the buffered transducer output signal. Portable test equipment or analyzers like SKF-CM's MicrologTM can be connected to this output without disturbing other system outputs.

 

Fault Detection:
 On board fault detection circuitry continuously monitors the transducer for normal operation. If a fault occurs, the output current is reduced to 2 mA to indicate the fault to the readout system. A red LED on the front of the unit is turned on to provide a local indication of the fault.

 

Displays And Assemblies:
Various display options, NEMA and explosion-proof enclosures, and assembled multi-channel systems are available. Consult your sales representative.

Ordering Example:

To order a standard process variable transmitter that accepts input from a 1-5 VDC sensor, with a Full Scale of 100%, specify Part Number: CMCP-580-01-01.

NOTES:

1.The Full Scale option specified at order entry is used by the factory for initial calibration. However, several other ranges can be jumper selected in the field.

2.Transducer and Full Scale options not listed in the above table are available. Contact your sales representative.
