- Front panel: Oxidation‑treated aluminum alloy
- Main circuit board: Multi‑layer FR‑4 fire‑retardant PCB
- Shield shell: Cold‑rolled steel anti‑electromagnetic interference housing
- Backplane bus connector: Gold‑plated high‑reliability industrial connector Structural Characteristics:
- Two‑slot plug‑in module for 3500 rack system
- Front panel multi‑LED status indication for module health, fault, alarm and bypass
- External termination design, field wiring connects to external termination hardware assembly 172109‑01
- Mechanical locking screws for rack mounting and fixing Working Principle: Temperature sensor signals are routed to external termination assembly 172109‑01, then transmitted into module internal circuit. After signal filtering, amplification and analog‑digital conversion, digital temperature value is obtained. Internal microcontroller compares real‑time measurement value with pre‑configured alarm setpoints. Measurement data transfers to rack backplane bus for host software reading. When alarm condition occurs, module sends trigger signal to relay modules to execute protection interlock logic. Installation Requirements:
- Occupies two adjacent slots in Bently 3500 instrument rack, power‑off rack before module plug‑in or removal, not hot‑swappable
- Field sensor wiring connects to external termination block 172109‑01, use shielded twisted‑pair cable
- Cable shield layer single‑end grounding at cabinet side
- Separate low‑level sensor wiring from high‑voltage power wiring
- Keep sufficient ventilation clearance for heat dissipation Usage Notes:
- Set sensor type, measuring range and alarm parameters in official 3500 configuration software before commissioning
- Do not mix RTD and thermocouple wiring inside one terminal group
- Inspect terminal screw tightness periodically for vibration‑heavy cabinet environment
- Avoid installation position with heavy dust, corrosive gas and high humidity
- Perform full‑loop calibration including field sensors during annual maintenance cycle
