- 4‑20mA Output Accuracy: ±0.2% full scale
- Response Time: Less than 1 second
- RTD Range:‑200°C ~ +850°C
- Thermocouple Range:‑100°C ~ +1370°C Material Composition:
- Front panel: Oxidized aluminum alloy
- Main PCB: FR‑4 fire‑retardant circuit substrate
- Shield housing: Cold‑rolled steel anti‑electromagnetic interference shell
- Backplane connector: Gold‑plated high‑reliability industrial connector Structural Characteristics:
- Two‑slot plug‑in module for 3500 rack
- Front panel LED indicators: OK, Channel Alarm, Global Fault, Bypass
- Rear side mates with I/O hardware assembly 133819‑02 for field signal termination
- Mechanical lock screws on left and right edges for rack fixing Working Principle: Field temperature sensor analog signals are transmitted into module via I/O assembly. Internal circuit implements signal conditioning and AD conversion. Real‑time temperature values are compared with alarm setpoints. Besides sending digital data to rack backplane bus, each channel converts temperature value into isolated 4‑20mA analog signal for external devices. Alarm condition triggers relay output request through system backplane busBaker Hugh…. Installation Requirements:
- Occupies two adjacent slots in Bently 3500 instrument rack
- Power off rack power supply before module installation or removal, not hot‑swappable
- Field sensor wiring uses shielded twisted‑pair cables, single‑end cabinet grounding
- 4‑20mA recorder output wiring must separate from high‑voltage power cables
- Match non‑isolated I/O assembly 133819‑02 for signal termination
- Keep sufficient air convection space for heat dissipation Usage Notes:
- Set sensor type, measurement range and 4‑20mA mapping range in configuration software before commissioning
- Do not apply over‑voltage to recorder output terminals
- Periodically inspect terminal screw tightness under continuous vibration environment
- Prevent corrosive dust and moisture entering module housing
- Perform whole‑loop calibration including field sensors during annual maintenance
