Product Introduction

is a multi-loop integrated temperature control module designed for the Series 90-30 platform, widely used in heat treatment furnaces, extrusion lines, packaging thermoforming, ovens and other thermal process equipment.

Core advantage: PID control executes locally on the module hardware, not within the main CPU. Even with all 8 active control loops, CPU scan cycle impact remains minimal. Each channel supports independent sensor configuration (thermocouple or Pt100 RTD) with built-in cold junction compensation. PWM outputs are primarily used to drive solid-state relays (SSR) for heater regulation.

Important Distinction

1. : Integrated input + onboard PID + PWM output temperature controller
2. IC693ALG220 / ALG221: Temperature input-only modules, no local control outputs

Platform Migration Note cannot be inserted directly into RX3i main rack. If deploying on RX3i systems, install on remote serial expansion racks via IC695LRE001 transceiver.

Revision Note: and IC693TCM302B share identical pinout and specifications, interchangeable. After replacement, verify all channel parameters.

 

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking. Inspect backplane gold pins for oxidation and bending; check terminal connectors and module housing integrity.
2. Live Testing: Mount onto validated Series 90-30 backplane. Configure sensor type and PID parameters, simulate setpoint adjustments, validate closed-loop temperature regulation, test sensor break diagnostic alarms, run continuous 24-hour stability test.
3. Electrical Testing: Monitor backplane 5V rail stability. Insulation resistance ≥10MΩ between field circuits and chassis protective ground.
4. Firmware Record: Document hardware revision; photograph front panel labels before clearing configuration data.
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: Series 90-30 modules cannot be hot swapped. Full rack power shutdown required before removal. ❗ External DC Power Mandate: PWM outputs require separate 18~36VDC external power supply; outputs will not activate without external field power. ❗ Thermocouple Wiring Rule: Use dedicated thermocouple extension cable; ordinary copper wire creates measurement offset errors. ❗ Inductive Load Protection: When driving inductive loads, install flyback suppression components; recommended load is SSR solid-state relays. ❗ Fail State Planning: Configure safe output state upon sensor open-circuit to avoid over-temperature hazards. ❗ Revision Interchange: and IC693TCM302B are plug-compatible. After replacement, recheck sensor settings, PID gains and limit alarms. ❗ ESD Risk: Static discharge damages analog front-end circuits, resulting in temperature reading drift and unstable control.

Replacement Guide

1. Pre-install: Lockout-tagout rack power; back up complete PLC project and all TCM channel parameter settings. Photograph slot layout and field wiring.
2. Removal: Disconnect all field input/output 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 project parameters, verify temperature readings, closed-loop PID response and sensor fault detection.

 

FAQ

Q: Does support hot swapping? A: No. Series 90-30 I/O modules do not support hot swap. Full rack power shutdown is mandatory.

Q: What is the difference between and IC693TCM302B? A: Identical core functionality. -B suffix represents updated PCB hardware revision. Mechanically fully interchangeable. Always perform full channel testing after replacement.

Q: Can this module run PID without CPU logic intervention? A: Yes. Closed-loop control runs locally on the module; CPU only exchanges setpoints and temperature feedback values.

Q: Can I install directly into RX3i main rack? A: No. Native Series 90-30 module. For RX3i systems, use IC695LRE001 to build remote serial expansion racks.

Q: Does this module accept 4–20mA transmitters? A: No. Native inputs limited to thermocouple and 3-wire Pt100 RTD.

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

Q: Will PID parameters remain stored on the module after replacement? A: All configuration resides in the PLC project. Module replacement requires re-downloading channel parameters.
