Product Introduction

is an onboard multi-loop temperature controller for Series 90-30 platform, widely used in furnaces, heat treatment, extrusion, packaging thermal forming and oven control. The biggest advantage: PID runs locally on the module, not inside the main CPU. This drastically lowers CPU scan time even when running 8 temperature loops simultaneously.

Each channel accepts thermocouple or Pt100 RTD, equipped with built-in cold junction compensation. Module outputs variable-duty PWM signals to drive solid-state relays for heating/cooling regulation.

Important Distinction

1. : Full function 8-loop integrated input + PID + PWM output module for Series 90-30 main rack
2. Pure thermocouple input modules (IC693ALG220 etc.): Only measure temperature, no onboard control outputs

Platform restriction: cannot be inserted directly into RX3i main backplane. To use on RX3i systems, install on remote serial expansion rack via IC695LRE001.

Suffix explanation: -B = hardware PCB revision, electrically and functionally identical to base IC693TCM302, fully plug-compatible.

 

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking and -B suffix. Inspect backplane gold pins for oxidation/bending; check dual terminal connectors and housing integrity.
2. Live Testing: Mount onto validated Series90-30 backplane. Configure sensor type and PID parameters, simulate temperature setpoint changes, verify closed-loop regulation, test open-sensor fault diagnostics, run continuous 24-hour stability test.
3. Electrical Testing: Monitor backplane 5V rail stability. Insulation resistance ≥10MΩ between field terminals and chassis protective ground.
4. Firmware Record: Document hardware revision; photograph terminal wiring layout before clearing configuration.
5. Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming temperature acquisition, PID control and fault diagnostic function validation prior to shipment.

 

Installation Pitfalls & Guide

❗ No Hot Swap Support: Module cannot be hot swapped. Full rack power shutdown mandatory before removal. ❗ External DC Power Mandate: PWM outputs require separate 18~36VDC external power; outputs will not activate without external supply. ❗ Thermocouple Wiring Guidance: Use dedicated thermocouple extension wire; avoid ordinary copper cable to prevent measurement error. ❗ PWM Load Recommendation: Drive SSR solid-state relays; avoid direct driving inductive loads without flyback protection. ❗ Sensor Open-Circuit Action Planning: Configure safe fail-state for heating loads upon sensor breakage. ❗ Revision Interchange: IC693TCM302 and are mechanically interchangeable. After replacement, re-download channel sensor types, PID gains and setpoint limits. ❗ ESD Risk: Static discharge damages analog front-end circuits, causing temperature reading drift and unstable control.

Replacement Guide

1. Pre-install: Lockout-tagout rack power; back up PLC project and all TCM channel parameter settings. Photograph slot layout and field sensor/output wiring.
2. Removal: Disconnect input/output terminal wiring, unlatch module and slide straight out without twisting backplane pins.
3. Install: Seat new into original slot, replicate all field wiring connections.
4. Power-on Test: Restore rack power; confirm PWR/RUN LED status, download PID & sensor configuration, verify temperature reading and closed-loop control response, test sensor break fault alarms.

 

FAQ

Q: Does support hot swapping? A: No. Series90-30 I/O modules do not support hot swap. Full rack power shutdown required.

Q: What is the difference between IC693TCM302 and ? A: Core function identical. -B denotes updated PCB hardware revision, fully plug-and-play interchangeable. Always verify all PID parameters after replacement.

Q: Can this module run PID without CPU logic? A: Yes. All closed-loop control executes locally on the TCM module; CPU only reads temperature values and setpoints.

Q: Can I install directly into RX3i main rack? A: No. It is native Series90-30 module. Use IC695LRE001 serial expansion transceiver for remote expansion rack deployment on RX3i systems.

Q: Does this module support 4–20mA transmitters? A: No. Native inputs only for thermocouple and Pt100 RTD.

Q: Will PID parameters stay stored on the module after power off? A: Configuration parameters are downloaded from the PLC project; save project backup before replacement.

Q: Can the 8 channels mix thermocouple and RTD sensors? A: Yes, each channel can be independently configured for different sensor types.
