DO232 Bachmann | M1 System 32-Output PLC Module

Product Overview

The DO232 (Model: DO232) is a high-density digital output module engineered for the Bachmann M1 automation system. Designed to interface with the M200 controller series, this module facilitates the connection of up to 32 digital signal receivers, including relays, contactors, signal lamps, and solenoid valves. The DO232 (Part Number: DO232) is built for high-performance switching where deterministic response times and reliability are critical for process integrity.

By utilizing a high-speed backplane interface, the DO232 (Order Number: DO232) ensures stable data transmission between the CPU and the field level. It features comprehensive galvanic isolation to protect internal logic from field-side electrical surges and noise. The module is ideally suited for complex machinery control, energy management, and factory automation environments where expertise in high-density I/O management is required.
