6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Overview
The ICS Triplex T8461 is a TMR (triple modular redundancy) digital output module that provides high availability and reliability for critical applications. It has 16 channels of 24/48 VDC output with automatic overcurrent protection, and is isolated from the PLC by a 2500 V impulse withstand opto/galvanic barrier. The module is also equipped with a watchdog timer to prevent errors due to communication loss or power failure.
