Description
The Bachmann DO232 is a high-performance, 32-channel digital output module designed specifically for seamless integration with the Bachmann M200 controller ecosystem, delivering reliable and flexible control capabilities for industrial automation applications across diverse sectors. 

Manufactured by Austria-based Bachmann electronic, a global leader in industrial automation solutions, this module is engineered to connect digital signal receivers such as relays, contactors, signal lamps, valves, and other 24 VDC-powered devices to the M200 controller, enabling precise and efficient control of industrial processes.

At the core of the DO232's design is its robust electrical architecture, featuring 32 individual digital outputs operating at a rated voltage of 24 VDC, with each channel capable of delivering a maximum current of 1 A. The outputs are strategically divided into two independent groups (channels 1-16 and 17-32), each with a maximum group current capacity of 8 A, providing flexibility in power distribution and load management.

A key advantage of the DO232 is its parallel connectability feature, which allows multiple outputs to be connected in parallel to drive higher current loads beyond the capacity of a single channel, significantly expanding its application versatility.
