Description
The Bachmann DIO248 is a versatile digital input/output module designed to control a wide range of industrial devices, including contactors, relays, and pneumatic or hydraulic valves, while also reading signals from digital sources such as sensors, photocells, or switches. Its flexibility allows efficient automation for both monitoring and actuation tasks.

This module provides 48 digital channels, with 16 channels configurable as either input or output. Up to 8 interrupt inputs enable event-driven reactions, while up to 4 counters allow precise position tracking, event counting, or frequency measurement. Each channel features LED status indicators for easy monitoring, and configurable input filters ensure reliable signal processing.

The outputs can be operated in PWM mode, optimizing energy consumption for inductive loads, with an adjustable hold time from 0 to 2 seconds specifically for valve control. Channels can also be connected in parallel to increase output capacity when operating in the same mode.

Built for demanding industrial environments, the DIO248 supports a supply voltage of 18–34 V DC (protected against reverse polarity), a maximum output current of 0.5 A per channel (total 16 A), and a switching frequency up to 1 kHz. It operates reliably in temperatures from –30 °C to +60 °C and can withstand storage temperatures of –40 °C to +60 °C, with relative humidity up to 95% non-condensing. Certified to CE, cULus, and CCC, it provides a robust and cost-effective solution for digital automation.
