Technical Specifications

FAQ

1. Channel Configuration
   All 24 channels are individually configurable as digital input or digital output via the AC500 Control Builder software. No hardware jumpers are required.
2. Output Load Capacity
   Each output channel drives 0.5 A at 24 VDC. The total module load must not exceed the power supply rating.
3. Sensor Power Supply
   The module provides 4 auxiliary 24 VDC terminals and 4 auxiliary 0 V terminals for powering field sensors.
4. Wiring Configuration
   The module supports 2-wire and 3-wire sensor configurations. Terminal assignments are printed on the module label.

Installation Guide

• Step 1: Mount the DC523 on the DIN rail. Ensure the rail is grounded per ABB installation guidelines.
• Step 2: Connect 24 VDC supply to the UP/L+ and ZP/M terminals.
• Step 3: Wire field devices to the pluggable terminals. Use 0.5 mm² to 1.5 mm² wire.
• Step 4: In AC500 Control Builder, configure each channel as input or output. Set input delay and output fail-safe states.
• Step 5: Download configuration to the CPU. Verify channel operation by toggling outputs and monitoring input states.

Selection Tips

Choose DC523 for 24-channel mixed digital I/O where channel direction changes based on application requirements. For pure 32-channel digital input, select DI524. For pure digital output, select DO5xx modules. The DC523 reduces spare parts inventory by combining input and output in one module.
