Core Functions

1. Multi‑sensor signal conditioning: Process RTD and thermocouple signals, mixed‑sensor configuration allowed on different channels.
2. Multi‑point temperature monitoring: Bearing‑metal temperature, lube‑oil temperature, motor‑stator temperature, casing and process‑temperature measurement.
3. Flexible alarm configuration: Alert and Danger temperature setpoints with configurable delay; generate rack‑system events, trigger relay‑module alarm output.
4. Recorder analog output: 6‑channel isolated 4‑20 mA output for DCS/PLC real‑time temperature acquisition (major difference vs 3500/60)Baker Hugh….
5. TMR redundant support: Can form triple‑modular‑redundant system with three identical modules for high‑safety machinery‑protection application.
6. Self‑diagnosis: Continuous open‑circuit / short‑circuit fault detection for RTD and TC sensors; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; six‑channel temperature measurement and analog‑output loses effectiveness during pulling‑out; other rack modules keep running.
2. Compatibility warning: ‑ Multiple rear I/O variants for 163179‑02; select non‑isolated or TC‑isolated I/O card according to site‑sensor type and anti‑interference requirement. ‑ Cannot swap main‑board or rear‑I/O between 3500/60 and 3500/61. ‑ For TMR triple‑redundant configuration, three identical 163179‑02 modules must be installed in adjacent slots of rack.
3. After replacement, check OK / Bypass LED status; download rack‑configuration project, verify temperature reading, alarm‑trigger function and 4‑20 mA recorder‑output.

4. Common failure mode: Front‑end signal‑conditioning‑circuit damage, component aging; sensor‑cable short‑circuit / open‑circuit may affect channel measurement.
