Triple Modular Redundancy Digital Output Module

T8891 ICS Triplex Rockwell Trusted TMR 40-Channel Digital Output Module
The T8891 is a genuine ICS Triplex (Rockwell Automation) 40-channel triple-modular-redundant (TMR) digital output module for the Trusted SIL 3 safety system. It delivers 24 VDC at 0.5 A per channel, with short-circuit protection, line-fault detection and < 1 ms output response, ensuring fault-tolerant control of valves, motors and alarms in the most critical oil & gas, chemical and power-generation applications.
Key Features & Benefits
  • 100% OEM ICS Triplex - serialized & factory-sealed
  • 40 digital outputs, 24 VDC, 0.5 A per channel
  • Triple Modular Redundancy (TMR) voted per channel
  • < 1 ms output response time (typical)
  • Short-circuit, over-temperature & line-fault detection
  • 2 kV impulse withstand isolation, ISA G3 coating
  • Hot-swap via Companion Slot - no system shutdown
  • Built-in 1 ms Sequence-of-Events (SOE) feedback
  • 0.1 A to 0.5 A current-limit per channel (configurable)
  • -40 °C … +70 °C operating, conformal-coated
  • SIL 3 (IEC 61508) certified by TÜV for safety loops
