Product Description
The IS220YAICS1A is a high‑integrity safety analog input module designed for use within GE’s Mark VIeS functional safety system architecture. Its key role is to acquire analog sensor signals from the field—such as transmitters measuring temperature, pressure, flow or other process variables—and convert those signals to digital form for the safety controller logic to evaluate. The module supports multiple high‑precision channels, built‑in diagnostics, and network redundancy via dual Ethernet ports.
The design emphasises safety, reliability and serviceability. With SIL 2/3 certification capability, the module is suited for safety critical applications. The analog input resolution (16‑bit) and channel count (up to 16) provide high fidelity measurement. The module also supports advanced fault detection and status monitoring indicators, enabling rapid diagnostics.
In system integration, the IS220YAICS1A plugs into the I/O network of the Mark VIeS system and connects to terminal boards that interface to field wiring. When installed in power generation, oil and gas, chemical or other high‑hazard industries, it becomes a vital component in the process safety chain, helping ensure safe, continuous, and reliable operation.
Applications
-
Safety analog input acquisition in gas turbine and steam turbine control systems (monitoring temperature, vibration, pressure, etc)
-
