The IS420UCSBH1A is designed to be mounted directly into the panel metal plate, with the device’s heat sink kept unobstructed to allow appropriate airflow.
The front-end design of the IS420UCSBH1A has three Ethernet ports for connecting to the R/S/TI/O network, and three additional ENET ports for connecting to HNMI, other controllers, Historians, and point-to-point connections. The front panel also has a USB port. Setting up the controller can be done using GE’s ToolboxST application.
The IS420UCSBH1A is a controller for the GE Mark VIe system. MKVIe is one of the most advanced Speedtronic systems GE has designed to control hydraulic, gas and steam turbine systems. IS420UCSBH1A is one of five UCSB modules available.
