ICS‑TRIPLEX T8800 40‑Channel 24 VDC Digital Input Safety Module

Product Description

T8800 belongs to the ICS Triplex Trusted triple‑modular‑redundant safety‑instrument system. It serves as a high‑density digital‑input acquisition card, 

collecting 24‑volt discrete‑switch signals from on‑site field‑devices and transmitting data to the main safety controller via the ISA‑system bus. It meets IEC‑61508 SIL‑3 safety‑grade 

requirements and is widely applied in petro‑chemical plants, natural‑gas stations, thermal‑power‑plant interlock‑control and hazardous‑process safety‑protection cabinets.3. Technical Specifications

Key Features

High‑density 40‑way isolated digital‑input gathers abundant on‑site switch‑state signals

TMR triple‑modular‑redundant hardware‑design greatly lowers single‑point‑failure risk

Full hot‑swap function permits on‑line module replacement without shutting‑down the safety rack

Built‑in channel‑by‑channel signal diagnosis, short‑circuit and wiring‑fault alarm feedback

Stable ISA‑bus high‑speed data‑transmission with strong electromagnetic‑interference resistance

Complies with SIL‑3 safety‑standard for critical emergency‑shutdown and interlock‑control

Compact plug‑in card‑type structure saves the inner installation‑space of SIS cabinet racks

Long service‑life and strict factory aging‑test adapt to non‑stop long‑time industrial‑operation
