Overview
The Opto 22 IDC5Q is a 4-channel AC/DC input module in the Quad Pak form factor. It accepts 12–32 VAC/10–32 VDC input with 5 VDC logic, providing a compact solution for monitoring discrete sensor and switch inputs across multiple voltage domains in industrial automation systems.
Key Features
- Quad Pak Format: Four single-channel I/O circuits in one package; each pair shares a common connection
- Wide Input Range: Accepts 12–32 VAC/10–32 VDC input voltages with 5 VDC logic
- Noise Rejection: Filtering on the input and hysteresis amplifier for high noise rejection and transient-free clean switching
- Isolated Channels: All inputs are isolated from each other
- Controller Compatible: Compatible with Opto 22 Optomux, Pamux, and Mistic protocol brain boards and mounting racks
