The Crouzet / Gordos-Arkansas SM-IDC5 is a digital input module that converts industrial-level voltage signals into 5 VDC TTL-compatible logic output for control system integration. Designed for harsh industrial environments, this module accepts input signals across a 3.3–32 VDC range and delivers reliable data acquisition with galvanic isolation.
## Technical Specifications
• **Input Voltage Range:** 3.3–32 VDC
• **Logic Output:** 5 VDC (TTL-compatible)
• **Input Current:** 34 mA
• **Logic Supply Voltage:** 5 VDC
• **Isolation Voltage:** 4000 V (transient-rated)
• **Turn-On/Off Time:** 1 ms
• **Output Type:** Open-collector
## Key Features
• Galvanic isolation rated to 4000 V protects downstream logic circuits from transient surges and ground potential differences.
• Open-collector output topology integrates easily into multi-input signal conditioning architectures.
• 1 ms switching response time suits real-time control feedback loops.
• Epoxy-sealed construction in white housing provides environmental sealing for factory floor deployment.
• 5-pin I/O rack mounting enables standard DIN-rail panel integration.
## Typical Applications
Digital signal conditioning for PLC inputs, motor control interlocks, sensor signal buffering, and discrete event monitoring in industrial automation systems. The wide input voltage acceptance and optical isolation make this module suitable for mixed-signal environments where sensor outputs range from 3.3 V CMOS to 32 V industrial logic levels.
## Compatibility & Integration
Direct pin-compatible replacement for Opto 22 IDC5, Grayhill IDC5, and Crydom IDC5 modules. Maintains identical mounting footprint and pinout, enabling retrofit into legacy control cabinets without redesign.
