Product Overview

The DO232 (Order Number: 00012240-00) is a high-density digital output module designed for the Bachmann M1 automation system. Occupying only a single-slot footprint, it provides 32 independent digital outputs, making it an ideal choice for driving high-volume industrial loads such as solenoid valves, contactors, and signaling devices.

Engineered for mission-critical reliability, the DO232 (00012240-00) incorporates robust galvanic isolation (500 V RMS) between the field electronics and the system backplane. Each channel is equipped with comprehensive protection against short circuits and thermal overload, ensuring the safety of the central processor and continuous system uptime even during localized field faults.
