Core Functions

1. Standard analog‑signal conditioning: Process 4‑20 mA transmitter current signal and ±10 Vdc voltage signal.
2. Multi‑type process‑variable monitoring: Pressure, flow, liquid‑level, compressor suction‑discharge pressure, active‑power and other process‑parameter acquisition.
3. Flexible alarm configuration: Alert and Danger setpoints with configurable delay; generate rack‑system events, trigger relay‑module alarm output.
4. TMR redundant support: Can form triple‑modular‑redundant system with three identical modules for high‑safety machinery‑protection application.
5. Self‑diagnosis: Detect transmitter loop fault, open‑loop / short‑loop condition; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; six‑channel process‑variable measurement loses effectiveness during pulling‑out; other rack modules keep running.
2. Compatibility warning: ‑ Multiple rear I/O variants for 163179‑03; select voltage‑type, isolated‑4‑20 mA or intrinsic‑safety‑barrier I/O according to site‑transmitter type and explosion‑proof requirement. ‑ Cannot swap main‑board or rear‑I/O between 3500/62 and 3500/60 / 3500/61 temperature‑monitor modules. ‑ For TMR triple‑redundant configuration, three identical 163179‑03 modules must be installed in adjacent slots of rack.
3. After replacement, check OK / Bypass LED status; download rack‑configuration project, verify analog reading and alarm‑trigger function.

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