Description:
The CMCP560A Isolated RTD Temperature
Monitors are compatible with 100 Ohm Platinum RTD inputs, and they provide a 4-20 mA output proportional to the
overall measurement. Each unit provides power for the associated
transducer, 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 CMCP560A Isolated RTD
Temperature 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.

Ordering Example:
To order a RTD
temperature monitor that accepts input from a 100 Ohm Platinum RTD, with a Full Scale of
0-250 Deg. F,
specify Part Number: CMCP560A-100P-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.
