Overview
The Reliance Electric 45C44 is a dual 24VAC/DC input module engineered for industrial automation and control applications within AutoMate distributed control systems. The unit is a dual AC/DC input module designed by Reliance Electric for use with the AutoMax line of products, and features two independently isolated input channels with individual LED status indicators. This module accepts both alternating current and direct current signals, making it versatile for environments where mixed signal types require simultaneous processing.
Key Features
- Two individually isolated input channels designed to accept either AC or DC input signals at specified voltages
- Two LED status indicators per channel—a green “POWER” indicator and a yellow “LOGIC” indicator that illuminates when the logic signal is active
- Electrical isolation between input signal and logic signal via photo couplers
- Minimum current resistor at each input, filtering, and stick-on label for model identification
- Allows processing of both 24 VAC and 24 VDC signals independently
- Suitable for on/off interface circuitry in limit switches, selector switches, push buttons, and PLC logic applications
