The DIO232 (Part Number: 00012242-00) is a mid-density digital I/O module for the Bachmann M1 system, offering 32 channels (16 inputs / 16 outputs) in a single-slot footprint. It provides robust galvanic isolation and LED status indicators per channel, making it ideal for distributed substations, industrial automation, wind energy, and maritime applications.

| Total Channels | 32 (16 DI / 16 DO) |
| Operating Voltage | 24 VDC (-15% / +20%) |
| Input Type | Type 1 / Type 3 per IEC 61131 |
| Output Current | 0.5 A per channel, short-circuit protected |
| Isolation Voltage | 500 V RMS (field to system electronics) |
| Status Indicators | LED per channel |
| Update Rate | Synchronous with M1 bus cycle |
| Thermal Range | −30 °C to +60 °C |
| Mounting | 1 slot on M1 backplanes (BS200 series) |
Used in wind turbine pitch control, marine engine monitoring, and factory automation. Often installed in distributed substations via FASTBUS modules (e.g., FS221/N) for local sensor and actuator control over long distances.
Can the DIO232 be used in high-vibration environments?
Yes. It features a vibration-proof locking mechanism compliant with maritime and energy certifications.
Does it use Harting PushPull connectors?
No. DIO232 uses standard Bachmann front connectors (screw or push-in). PushPull is used only on FASTBUS communication modules like FM221/FM222.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
