The GE IS220PSCAH1A 336A4940CSP9 is a serial Modbus communication I/O module manufactured by General Electric (GE) as part of the Mark VIe family used in gas turbine control systems. With its high-speed serial communication capability, support for multiple communication protocols, remote management capabilities, high reliability and stability, easy integration, rugged metal housing design and scalability, the module is widely used in industrial control fields such as gas turbine power generation systems, deep sea drilling equipment (BoP), seawater desalination facilities, gas compression systems, etc.

The module has six individually configurable serial transceiver channels, supports RS485 half-duplex, RS232 and RS422 standards, and is capable of providing up to 32 digital I/O points, eight analog I/O points, and two analog outputs. In addition, the IS220PSCAH1A module features constant current short-circuit protection that limits the output current when the voltage drops to safely protect the control components from direct short circuits and equipment failures. Once the short circuit problem is resolved, the module will automatically resume providing full voltage power.
