GE IS220YDOAS1B

الوصف

The GE IS220YDOAS1B is a Discrete Output I/O Pack used in the GE Mark VIe control system. This module is essential for controlling on/off devices in the field, making it a critical component in industrial automation and turbine control applications.

Functionality and Applications

The IS220YDOAS1B, also referred to as a YDOA pack, manages discrete (on/off) output signals. It works by sending a command from the Mark VIe controller to energize or de-energize relays, which in turn control a variety of external equipment. The module is specifically designed to work with terminal boards that feature relay and fuse feedback, allowing the system to monitor the status of the controlled device.

Key applications for this module include:

• Controlling solenoid valves to manage fluid flow.
• Operating contactors or motor starters for pumps and motors.
• Activating alarms or indicator lights to alert operators of system status.
• Providing control signals for other discrete devices.

The module’s design allows it to control up to twelve potential relays and provides feedback on their status. It also features LED indicators for each of the twelve outputs, which turn yellow when a relay is commanded to energize.
