DSRF197 3BSE019297R1

The ABB DSRF197 3BSE019297R1 is a digital signal relay unit designed for use in industrial control systems. It is part of ABB’s S800 I/O System and is used to convert digital input signals into relay outputs. This allows for the control of actuators, alarms, and other devices that require discrete on/off signals.

Key Features:

8 Digital Inputs: The DSRF197 can handle 8 digital input signals.
8 Relay Outputs: It has 8 corresponding relay outputs that switch based on the digital inputs.
Form C Relays: The relay outputs are form C (SPDT) relays, providing a common terminal, a normally open (NO) contact, and a normally closed (NC) contact.
Isolated Channels: The input and output channels are isolated from each other to prevent electrical noise and ground faults from affecting signal integrity.
DIN Rail Mount: The module is designed for easy mounting on DIN rails, commonly used in industrial control panels.

Applications:

The ABB DSRF197 3BSE019297R1 is likely used in a variety of industrial automation applications where digital signal processing and relay control are required, such as:

Machine Control: Sending control signals from a PLC or other controller to operate machine actuators, valves, and other devices.
Alarm Systems: Triggering alarms based on digital input signals from sensors or safety devices.

Process Control: Switching equipment on or off based on process parameters monitored by digital sensors.
