Installation Guidelines

CRITICAL WARNING: Electrical Hazard

Disconnect all power sources to the PLC rack and verify system de-energization using a calibrated voltmeter before handling, installing, or removing this module. Failure to comply can result in severe injury, death, or equipment damage. Follow all applicable Lockout/Tagout (LOTO) procedures.

1 De-energize System: Ensure the SIMATIC S7-200 PLC system is completely powered down and locked out.
2 Mount Module: Align the module with an available slot on the S7-200 I/O bus. Firmly press the module onto the bus connector until it securely clicks into place.
3 Connect Sensor Wiring: Terminate the RTD sensor leads at the module's terminal block. Use shielded, twisted-pair instrumentation cable for all sensor connections to minimize electrical noise interference.
4 Ground Cable Shield: Connect the cable shield's drain wire to the designated chassis ground terminal at the PLC end only. Do not connect the shield at the sensor end to prevent ground loops.
5 System Power-Up: After verifying all connections, remove LOTO devices and re-apply power to the system. Configure the new module within the PLC programming software to match the connected RTD sensor types.
