Acromag IP445 Isolated Digital Output Module

The Acromag IP445 is an isolated digital output module designed for industrial applications, offering 32 solid-state relay (SSR) outputs. This module is engineered to provide robust and reliable digital output control while ensuring the protection of sensitive control systems from electrical noise and surges through its isolation capabilities. It is particularly well-suited for integration with Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS). The IP445 module supports a wide range of bipolar (AC or DC) voltage switching, providing flexibility in its application. Each output port can be configured for either high-side or low-side switching, with TTL compatibility when configured for low-side switching via on-board socketed pull-up resistors. The outputs are grouped into four 8-channel ports, with each port isolated from the logic and from other ports via solid-state relays. Readback buffers are integrated to simplify the monitoring of output status. For comprehensive closed-loop monitoring of critical control signals, the IP445 can be used in conjunction with an Acromag IP440 input module.
