About the IC3600KVSA1B
The Zero Speed Relay card marked IC3600KVSA1B is a GE FANUC component for the Mark I/Mark II series. Designed for steam or gas turbine management, the MKI and the MKII were the first of the Speedtronic systems released commercially by General Electric. Both series were designed to perform five main functions, including control of the turbine output power, maintaining the maximum output to within the unit’s capability, performing start-up sequencing for the turbine and its auxiliaries, providing protection for the turbine in case of a non-recoverable system failure, and annunciating and monitoring any malfunctions occurring within the control system, the turbine, and its auxiliaries.
The IC3600KVSA1B has one GE reed relay component placed at the center of the board. These types of relays tend to be small, lightweight and fast. Reed switches use an electromagnet for control. The relay is marked on its top surface with a relay diagram. It is also marked 28 VDC, Cont 50 VA, 68A997168A02 and NP68A997229 P2. Several colored wires are fastened from one end of the relay to the line of pins located on the long edge of the IC3600KVSA1B.
The IC3600KVSA1B is built with two types of transistors, five in all. It has one trim potentiometer, which may be used for voltage division. The board has resistors (carbon composite and other material,) capacitors (usually ceramic,) and diodes. Diodes on this board are marked. The board has one integrated circuit.
The IC3600KVSA1B has a line of right-angled pins located on one edge. The pins connect by wires to the rest of the system and facilitate communication.
