DIO280 Bachmann Digital Input/output (I/O) module

Description The Bachmann DIO248, DIO264, and DIO280 are versatile digital input/output (I/O) modules designed for controlling digital consumers such as contactors, relays, pneumatic and hydraulic valves. They are also suitable for reading signals from digital sensors, detectors, or switches. These modules feature configurable interrupt inputs and counters, making them ideal for various industrial automation applications.

Features

• Digital Channels: Available with 48/64 or 80 digital channels.
• Configurable Channels: 16 channels can be configured as either inputs or outputs.
• Interrupt Inputs: Equipped with 8 configurable interrupt inputs for rapid event response.
• Counters: Up to four 32-bit counters for applications such as position detection and goods counting.
• PWM Output Mode: All outputs can operate in PWM mode for energy-saving operation of inductive loads, with a configurable hold time of up to 2 seconds.
• Parallel Connection: Outputs can be connected in parallel if operated in the same mode.
• Status Display: Each channel has an LED status display for easy monitoring.
• Power Supply: Operates on a supply voltage of 18 to 34 VDC, with protection against reverse polarity.
• Compact Design: Cost-effective and space-saving design.
