Description:
The CMCP565A Isolated Thermocouple Temperature Monitor are compatible with type J and K thermocouple inputs, and they provide a 4-20 mA output proportional to the overall measurement. Each unit processes the signal to determine overall amplitude, and outputs a 4-20 mA dc current that is proportional to a user specified range such as 0-250 Deg. F. Combining monitors with an existing PLC or DCS system results in a high density, low cost monitoring system. The alarm feature 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. This includes both the unfiltered vibration signal, and the DC bias voltage. 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.

Alarms:
The CMCP565A Series Monitors have two independent set points, with LED alarm indicators and output relay contacts (Alert and Danger). Set points are adjustable via potentiometer, from 0 to 110% of full scale. Each has an adjustable delay of 1 to 10 seconds. Relay contacts can be independently configured by the user for either Normally Open (NO) (Standard) or Normally Closed (NC) operation. Relays are normally de-energized and can be configured for latching or non-latching (standard) operation. Latched alarms may be reset locally or by remote contact closure. SPST Relay contacts are rated 5 Amps @ 30 Vdc or 250 Vac for resistive loads. The monitors also have set point multiplication of 3X via contact closure (2X available).

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