Features:

  • Triple Modular Redundant architecture delivers high fault tolerance and enhances system reliability for safety-critical applications.
  • Integrated diagnostics and configurable line monitoring help identify open-circuit and short-circuit wiring faults automatically.
  • Online hot replacement capability minimizes process interruptions and supports continuous plant operation.
ICS Triplex T8800C is designed to provide dependable digital signal acquisition for demanding industrial control environments. Supporting 16 digital inputs with a 24 VDC operating voltage and a 24 kHz operating frequency, ICS Triplex T8800C enables accurate signal handling while maintaining stable communication through the MODBUS RTU protocol. An operating temperature range of -20°C to +70°C allows ICS Triplex T8800C to adapt to various installation conditions across industrial facilities. Such characteristics make the module suitable for applications where system availability and signal integrity are essential.

Built around the Trusted® TMR 24 Vdc Digital Input technology, ICS Triplex T8800C incorporates 40 Triple Modular Redundant input channels to improve fault tolerance and maintain dependable operation. Each channel uses triplicated voltage measurement based on sigma-delta input circuitry, and configurable voltage thresholds determine the reported input state. When line-monitoring devices are connected to field switches, ICS Triplex T8800C can independently detect open-circuit and short-circuit cable conditions for every channel. Combined with automatic diagnostics and self-testing, the module provides comprehensive fault detection capabilities while maintaining a 2500 V impulse withstand opto/galvanic isolation barrier.

In process industries, power generation facilities, and critical automation systems, ICS Triplex T8800C offers valuable support for maintaining operational continuity. The onboard Sequence of Events reporting function records status changes with a resolution of 1 ms, providing detailed event tracking for troubleshooting and analysis. Front panel LEDs indicate channel conditions, field wiring faults, module health, and operating modes including Active, Standby, and Educated states. In addition, ICS Triplex T8800C supports online hot replacement through Companion Slot or SmartSlot configurations, reducing maintenance downtime. TϋV certification according to IEC 61508 SIL 3 further demonstrates the suitability of ICS Triplex T8800C for high-integrity safety applications.

The T8800C ICS Triplex Digital Input FTA Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
