The ICS Triplex T8891 Trusted Speed Monitor Output Field Termination Assembly (SOFTA) is a DIN rail-mounted device designed to function as an output field interface for one rotating machine group when integrated into a Trusted T8442 Triple Modular Redundant (TMR) Speed Monitor system.
This unit provides normally open and normally closed volt-free contact outputs, allowing for use in energized-to-trip and de-energized-to-trip configurations. The quad-redundant, fault-tolerant relay output channels ensure that failure of any single relay or contact does not affect the load or its control.
Key features include:
- Dual fault-tolerant volt-free contact output channels
- Configurable as normally open or normally closed contacts
- Quad-redundant relay structure for maximum reliability
- Load current feedback for enhanced monitoring
- Contact status feedback to detect welded or stuck contacts
- Force-guided contact safety relays for improved diagnostics
- Standard DIN rail mounting
- Replaceable relays, fuses, and current sensors
