Technical Specifications PLC Platform: GE Series‑90‑30 Input Channels: 4‑channel analog input Signal Type: 4‑20mA, 0‑10VDC Resolution: 12‑bit Operating Temperature Range: 0 ℃ to +60 ℃ Storage Temperature Range: ‑40 ℃ to +85 ℃ Mounting: Series‑90‑30 PLC rack slot‑mount
Functional Features Multi‑channel analog‑digital conversion. Software configurable channel signal range. Channel fault diagnosis function. Backplane bus data communication with CPU. Front‑panel LED status indication.
Application Scenarios Process industry signal acquisition, water treatment, factory automation, Series‑90‑30 PLC spare‑part maintenance projects.
Performance Parameters Conversion accuracy: ±0.5% full scale
Structural Characteristics Standard Series‑90‑30 rack‑mount module. Front‑panel LED status indicators. Rear gold‑plated backplane connector for PLC rack bus interface.
Working Principle Field analog current or voltage signals enter module internal ADC circuit. Analog signals are converted into digital values. Digital data is transmitted to Series‑90‑30 CPU through rack backplane bus for user logic processing.
Installation Requirements Insert into Series‑90‑30 PLC rack designated slot, ensure full connector engagement. Maintain cabinet ventilation environment. Apply ESD anti‑static protection while handling module.
Usage Notes Configure channel signal type and range in PLC programming software. Avoid input signal over‑range condition. Power‑off rack before module plug‑in or removal.
