1.2.4 Temperature Monitoring Module (TMM)
The TMM module supports 6-channels of
thermocouple, RTD, and/or Process
Variable inputs. The TMM conditions the
transducer signals, including filtering and
noise rejection.
Each channel input is independently
configurable allowing you to mix
thermocouples, RTDs, and Process Variable
channels. The following sensor types are
permitted.
Type J Thermocouple
Type K Thermocouple
Type T Thermocouple
Type E Thermocouple
100-ohm platinum RTD (0.00392)
100-ohm platinum RTD (0.00385)
120-ohm nickel RTD
100-ohm copper RTD
10-ohm copper RTD
The TMM also includes 4 relay outputs.
Each relay output is programmable to trip
independently and may include logic
elements from other cards in the rack
(including UMM).
Six analog outputs (4 to 20 mA) can be
configured to be driven from any
measurement in the TMM.
A TMM card may be used as a Process
Variable input by running the 4-20 mA signal
through an external 68-ohm resistor. The
TMM does not provide transmitter power.
The TMM is autonomous and performs all
functions internally.

CAUTION
A six channel TMM can be used for Process Variable (4-20 mA) Channels. However,
wiring mistakes (over voltage) will damage the TMM.
For a more robust solution, consider using a UMM for process variable inputs.
