ICS Triplex |T7481A|Monitored Guarded Digital Output Module
ICS Triplex T7481A Monitored Guarded Digital Output Module
Description
The ICS Triplex T7481A is a 24V DC monitored guarded digital output module for Regent and Regent+Plus low-density I/O in Trusted safety systems.
Features
- Monitored outputs for safety assurance
- Fail-safe and fault-tolerant configurations
- Certified for safety-critical applications
Technical Specifications
- Output Voltage: 24V DC
- Configuration: Fail-safe single module (1oo1) or fault-tolerant dual modules (2oo2)
