This unit
The Acromag IP440-1 is a 16-channel isolated digital input module engineered for industrial automation and control systems. It acquires digital signals across 0–30 VDC with 500 VDC channel-to-channel and channel-to-ground isolation, delivering 10 ms typical response time and configurable digital filtering. Individual LED status indicators and reverse voltage protection provide real-time feedback and circuit safeguarding in harsh environments.
