Bihl+Wiedemann BWU2234 Overview
The Bihl+Wiedemann BWU2234 is an AS-Interface safety input module. It is designed to connect standard binary sensors and actuators to an AS-Interface safety network, especially suitable for automation applications requiring safety functions.
Product Detailed Description
Function:
The BWU2234 allows the connection of up to four standard binary input devices (such as safety sensors, safety switches) to an AS-Interface safety network.
It converts these input signals into the AS-Interface safety protocol so that a safety controller can process them.
The module has integrated safety functions and complies with relevant safety standards (e.g., EN ISO 13849-1).
It typically features LED indicators for power supply, AS-Interface communication, and input status.
The module is powered via the AS-Interface bus.
Features:
Connection of 4 safety inputs.
Compact design for DIN rail mounting.
Integrated AS-Interface safety communication.
Complies with safety standards.
LED status indication.
