The DS215KLDCG1AZZ03A and DS200KLDCG1AAA form a matched DC input control board assembly for GE Speedtronic Mark V turbine control systems. This dual-board set serves as an advanced discrete signal acquisition unit, responsible for receiving, conditioning and processing multi-channel DC digital signals from field turbine devices. It delivers reliable status data to the main processor to execute turbine interlock logic, operational monitoring and safety protection strategies.

The assembly is constructed with industrial multi-layer PCB and integrated EMI suppression and surge protection circuits, capable of adapting to power plant environments with electromagnetic interference and temperature fluctuations. It supports stable 24/7 continuous operation under long-cycle working loads. The matched board combination is widely used as replacement spare hardware for maintenance and upgrading of aging gas and steam turbine control racks.
