Product Description

GE Fanuc is the manufacturer of IC693TCM303.Itis one of the Temperature Control Modules or TCM. TCM provides temperature control for as many as eight channels. There are two identical models for TCM differing in resolution ratings and temperature range. The TCM comes with important features, including its ability to operate in a closed loop or open loop mode. It can relay an output and a thermocouple for each of the terminals and has a voltage capability of 12V in common mode. It can report and detect for a reverse and open thermocouple, and can also report and detect when the temperature is out of tolerance.
The module has two plug-in connectors. They connect the external power source for the output relays, RTD and the field devices (such as thermocouples and relays). Terminals with captive screw are on the connectors. It makes field wiring a connection easy. The front cover of the module comes with a label of each terminal’s signal name for every available connector. Left-hand side connectors are specifically for input connections, and right-hand side connectors are for output connections. LED indicators are present to indicate the current state of the module. The states include External Power or P, Run or R, Fault or F, Short or S, and Output Status (1-8).  The IC693TCM303 is an extended or upgraded range of the IC693TCM302. The temperature range for Thermocouple J and Thermocouple L for IC693TCM303 is 0°C to 750°C. Temperature ranges for Thermocouple R for IC693TCM302/303 are 0°C-600°C/0°C-1050°C respectively, and the resolution is 12bits/0.5°C for IC693TCM303.

Customer Questions and Answers

  • Question:  What is an IC693TCM303?  Answer:  The IC693TCM303 is a Temperature Control module.  This module is a high performance module and it provides 8 channels of thermocouple input, 1 RTD and 8 24 VDC channels of control output in a single Series 90-30 module. It provides temperature monitoring and temperature control functions.
  • Question:  Does this module operate in closed or open loop mode?  Answer:  It can operate in both, which alleviates the PLC of providing the temperature control duties.
  • Question:  What does closed loop mean?  Answer:  This is when the module is in auto mode. 
  • Question:  How many seconds can you program the PWM output period for?  Answer:  The IC693TCM303's PWM output period can be programmed from 0.1 to 60 seconds.
  • Question:  What does open loop mean?  Answer:  This is when the module is in manual mode.
  • Question:  What diagnostics does the TCM provide?  Answer:
    • Start up test (POST)
    • Uninterrupted monitoring and signaling of the external power status using a front facing LED
    • Checks thermocouple status for each section and signals 2 types of flaws
    • Signals thermocouple error status of each section
  • Question:  What software do you use for the configuration of IC693TCM303?  Answer:  You should use the Logicmaster 90-30 configuration software.
  • Question:  How many steps are in the configuration of IC693TCM303?  Answer:  There are 2 steps: I/O Rack Configuration and Module Configuration
  • Question:  What is my next step if my IC693TCM303 is not working?  Answer:  Your product may need repair
