Technical Specifications Power supplied by rack back‑plane bus; Multi‑channel analog input; Galvanic channel isolation Operating temperature:0℃~+60℃; Storage temperature:‑40℃~+85℃; Humidity:5‑95% non‑condensing Mounting:rack plug‑in mounting
Functional Features Multi‑channel analog signal acquisition and A/D conversion. Input signal filtering. Hardware and channel self‑diagnosis. Front‑panel LED power and fault status indicators.
Application Scenarios Analog signal conversion for GE industrial control racks. Process‑industry pressure, flow measurement signal acquisition. Spare replacement A/D unit for cabinet maintenance.
Performance Parameters Stable high‑accuracy A/D conversion performance. Good industrial‑field noise suppression capability. Reliable channel fault detection.
Material Composition Flame‑retardant plastic housing. Multilayer conformal coated PCB. Analog‑conditioning and A/D conversion circuits, back‑plane plug‑in connector and field analog‑signal terminals.
Structural Characteristics Standard rack plug‑in module. Rear connector connects rack back‑plane bus. Front‑panel field‑signal wiring terminals and LED indicators. Metal locking screw for rack‑slot fixation.
Working Principle Field analog signals enter front‑panel terminals. After isolation and filtering, analog values convert to digital data. Digital measurement data transmits to controller CPU via rack back‑plane bus.
Installation Requirements Power off control rack before installation. Insert ADU232 into designated rack slot and tighten fixing screw. Connect field analog‑signal cables. Restore rack power, configure analog‑range parameters and verify measurement data.
Usage Notes Prohibit hot‑plug under powered condition. Signal cable shielding grounding follows site specifications. Anti‑static handling is required.
