1.Product Positioning and Core Functions

Type:

This digital input/output(DIO)control module is a key component for discrete signal processing in the GE DS3800 series,focusing on high-reliability digital signal acquisition and control command output.

Core Application:

Input Function:

Acquires digital signals from gas turbine field devices(such as valve status,circuit breaker opening/closing,safety interlock contacts,etc.).

Supports dry contact(passive contacts)or wet contact(active signals,such as 24V DC)inputs and is compatible with a variety of sensor types.

Output Function:

Drives actuators such as solenoid valves,relays,and indicator lights to implement physical actions in control logic(such as opening a fuel valve or triggering an alarm).

Output channels feature short-circuit protection and overload capability to ensure system safety.

System Role:

Serves as the digital signal interface between the Mark II/IV controller and field devices,isolating and converting safety-critical signals.2.Key Technical Parameters
