ABB PCD232A101 PEC80‑CIO Combined Input Output Module

Technical Specifications Model: PCD232A101 Part Number: 3BHE022293R0101 Power Supply: DC 9‑36 VDC wide‑range power input Digital Input Channels: 12 channels, galvanic isolated 24 VDC / 48 VDC Relay Output Channels: 16 channels, contact rating up to 250 VAC 10 A Analog Input Channels: 3 channels, ±10 V / 4‑20 mA configurable Analog Output Channels: 3 channels, ±10 V Mounting Mode: Rack plug‑in installation Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE, UL

Functional Features High‑density mixed I‑O integrates digital input, relay output, analog input and analog output channels. Galvanic isolation between each channel and internal system bus restrains field interference. Relay contact output realizes high‑capacity switching control for field interlock circuits. Front‑panel LED indicators show real‑time status of each input and output channel. High‑speed data interaction with excitation main controller via rack back‑plane bus. On‑board self‑diagnosis detects channel overload, open‑circuit and internal hardware fault. Supports redundant power supply input for improving system operation stability.

Application Scenarios Spare‑part replacement for PCD232A101 module inside ABB UNITROL generator excitation cabinet. Field signal acquisition and interlock output for synchronous generator excitation control in hydropower and thermal power plants. Hardware renewal and maintenance for AC800PEC control platform.

Installation Requirements Insert PCD232A101 fully into target rack slot and tighten front‑panel locking screw. Connect field analog, digital and relay load cables to front‑side terminals strictly complying with signal definition. Complete protective earthing according to cabinet grounding specification. Reserve sufficient ventilation clearance around module slot. Ambient operating temperature shall keep within 0 ℃ to +60 ℃ without condensation. Verify each input‑output channel function after power‑on commissioning.
