Technical Specifications Power supplied by rack back‑plane bus; Multi‑channel RTD sensor input; Galvanic channel isolation Operating temperature:0℃~+60℃; Storage temperature:‑40℃~+85℃; Humidity:5‑95% non‑condensing Mounting:rack plug‑in mounting
Functional Features Supports multiple RTD sensor types. Signal conditioning and noise filtering. Sensor wire breakage detection. Front‑panel LED status and fault indicators.
Application Scenarios Temperature signal acquisition for GE industrial control racks. Power plant and process‑industry equipment temperature monitoring. Spare maintenance replacement module.
Performance Parameters Stable temperature conversion accuracy. Sensor open‑circuit fault detection capability. Strong field‑noise suppression.
Material Composition Flame‑retardant plastic housing. Multilayer conformal coated PCB. RTD signal conditioning circuits, A/D chip, back‑plane connector and field sensor terminals.
Structural Characteristics Standard rack plug‑in module. Rear connector connects rack back‑plane bus. Front‑panel sensor wiring terminals and LED indicators. Metal locking screw for rack‑slot fixation.
Working Principle RTD sensor signals are connected to front terminals. On‑board circuit converts resistance variation into digital temperature values. Data transmits to controller CPU through rack back‑plane bus.
Installation Requirements Insert module into rack slot and tighten fixing screw. Connect RTD sensor cables. Restore rack power, select sensor type parameter and verify temperature reading.
Usage Notes Hot‑plug under powered status is forbidden. Sensor cable shielding grounding follows site requirements.
