DIO216 Digital I/O Module Bachmann

Product Description

The DIO216 (Order Number: 00012240-00) is a high-density digital interface module designed for the Bachmann M1 controller platform. It provides 16 individually configurable digital channels, allowing each point to be defined as either an input or an output. This flexibility enables engineers to precisely match I/O requirements to the application, significantly reducing the need for multiple discrete module types within a control cabinet.

Built for demanding industrial environments, the DIO216 incorporates comprehensive galvanic isolation to protect the internal system bus from field-side disturbances. Each channel features an integrated status LED for fast local diagnostics, while the output stages are engineered to safely drive inductive loads, supported by built-in protection circuitry. Full integration with Bachmann SolutionCenter allows centralized configuration, diagnostics, and real-time signal monitoring.

Technical Specifications

System Comparison: DIO216 vs. DIO232

The DIO216 offers 16 flexible, high-current-capable channels, making it well suited for applications requiring mixed I/O usage, inductive loads, or enhanced thermal margins. In contrast, the DIO232 increases channel density to 32 points, favoring applications where space efficiency and higher point count are prioritized.

In practice, the DIO216 is frequently selected in maritime, energy, and heavy industrial applications, where its higher per-channel current capacity and improved thermal performance provide long-term operational advantages.

Frequently Asked Questions

Can channels be changed from Input to Output during runtime?
No. Channel configuration on the DIO216 is defined within the hardware configuration of the M1 system. Any change between input and output assignment requires a project download and system restart, ensuring deterministic and predictable signal behavior.
