Technical Specifications

FAQ

1. Signal Type Selection
   Analog input channels support current and voltage signals. Each channel is individually configurable via AC500 Control Builder software.
2. Bipolar Output
   The two analog output channels support bipolar ±10 VDC signals. This is required for servo valve and motor drive control applications.
3. Resolution
   Analog inputs provide 11-bit plus sign resolution. Analog outputs provide 12-bit plus sign resolution. This delivers 0.05% measurement accuracy.
4. Sensor Wiring
   Analog inputs support 2-wire connection. Analog outputs use 1-wire connection. Shielded twisted pair cable is required for noise immunity.

Installation Guide

• Step 1: Mount the AX561 on the S500 terminal base. Ensure the DIN rail is properly grounded.
• Step 2: Connect 24 VDC supply to the module power terminals.
• Step 3: Wire analog signals using shielded twisted pair cable. Ground the shield at the module end only.
• Step 4: In AC500 Control Builder, select signal type per channel (mA or V), enable open-circuit detection, and set scaling.
• Step 5: Calibrate using precision signal source. Verify 4 mA reads 0% and 20 mA reads 100% of engineering range.

Selection Tips

Select AX561 for 4-channel analog input and 2-channel analog output in a single S500 module. It eliminates the need for separate AI and AO modules in small systems. For higher channel density, use dedicated AI5xx and AO5xx modules. Verify signal range requirements match the module specifications.
