Product Overview
PV2121ED160012CT is a 16-point digital input I/O pack manufactured by GE for the Mark VI Speedtronic turbine control platform. It collects 24VDC discrete field signals from limit switches, pressure switches, relay auxiliary contacts and sends status data to the main turbine controller.
This module has been discontinued by the original manufacturer. We supply fully inspected and function-tested original surplus PV2121ED160012CT cards. It serves as critical spare replacement for legacy power plant gas turbine, steam turbine and balance-of-plant control racks.
