IRC5 Safety Communication Unit | ABB 3HNE00421-1 DSQC378B

Product Description

Dual-Function Safety and Network Communication Interface

The DSQC378B (Part Number: 3HNE00421-1) is a high-integrity safety relay board specifically engineered for ABB IRC5 robot controllers. Unlike standard I/O boards, the DSQC378B (3HNE00421-1) serves as a critical junction for the robot's safety architecture, processing redundant signals from emergency stop (E-Stop) buttons, enabling devices (dead-man switches), and protective gate interlocks. Additionally, this module provides CC-Link communication capabilities, allowing the IRC5 system to interface seamlessly with Mitsubishi-based PLC networks or other CC-Link compatible field devices while maintaining strict adherence to industrial safety standards such as ISO 13849-1.
