Technical Specifications

FAQ

1. Input Wiring
   Inputs support both sink and source wiring configurations. The wiring mode is determined by the connection polarity at the terminals.
2. Output Load
   Each transistor output drives 0.5 A at 24 VDC. The total module load must not exceed the auxiliary power supply rating.
3. Short-Circuit Protection
   Outputs feature electronic short-circuit and overload protection. The module automatically limits current during fault conditions.
4. Signal Delay
   Input delay is 8 ms. This filters mechanical switch bounce and provides stable signal detection.

Installation Guide

• Step 1: Mount the DX561 on the S500 terminal base. Slide the module onto the DIN rail until the connector engages.
• Step 2: Connect 24 VDC supply to the module power terminals.
• Step 3: Wire digital inputs to switches, sensors, or proximity detectors. Wire outputs to solenoids, relays, or indicators.
• Step 4: In AC500 Control Builder, assign input and output addresses. Configure input filter time if required.
• Step 5: Download configuration and test each channel. Verify input state changes in the online monitor and confirm output actuation.

Selection Tips

Select DX561 for 8-channel digital input and 8-channel transistor output in a single S500-eCo module. It saves panel space in mixed I/O applications. For relay outputs driving AC loads, use DX571. For higher input density, use DI524 (32 DI).
