AIO208 Bachmann | M1 System 8-Channel AI/DI 8-Channel DO

Product Overview

The AIO208 (Model: AIO208) is a versatile, high-density all-in-one I/O module engineered for the Bachmann M1 automation system. Designed to provide maximum flexibility in a single slot, the AIO208 (Part Number: AIO208) combines 8 high-precision analog/digital inputs with 8 configurable outputs. This architectural efficiency makes it an ideal solution for applications where space is limited but diverse signal processing—such as monitoring temperature sensors alongside digital limit switches—is required.

Contrary to hobbyist-grade decoders, the industrial-grade AIO208 (Order Number: AIO208) is built for mission-critical process control and energy management. It features full galvanic isolation and deterministic data transmission via the M1 backplane. Each output channel is capable of driving up to 1.0 A, providing sufficient power for industrial solenoids, signal lamps, or auxiliary relays. Its robust hardware design ensures long-term reliability in demanding environments from -30°C to +60°C.
