ABB DI818 3BSE069052R1 Digital Input Module

The ABB DI818 is a digital input module designed to work with ABB's S800 I/O system, specifically the ABB Competence? System 800xA process automation platform.

It is designed to collect digital signals from a variety of external devices and input this information into a programmable logic controller (PLC) or distributed control system (DCS).

Features:

32 Digital Inputs: Can process signals from up to 32 separate devices simultaneously.

24VDC Inputs: The module operates on a 24V DC power supply.

Current Sinking Inputs: This type of input configuration allows a connected device to source current to activate an input channel.

Isolation Groups: The 32 channels are divided into two electrically isolated groups of 16 channels each. This isolation helps prevent electrical noise or ground loops from affecting signal integrity.

Voltage Monitoring: Each group has built-in voltage monitoring that can be used to detect power supply problems or wiring faults.

Compact design: With dimensions of 45 mm (1.77 in) in width, 102 mm (4.01 in) in depth, 119 mm (4.7 in) in height and weighing approximately 0.15 kg (0.33 lb), it is suitable for applications with limited space.
