GE  DS200ACNAG1 ADD‌   Relay

DS200ACNAG1ADD is an ARCNET (Additional Resource Computer Network Day) card manufactured by General Electric for its MarkV series. The Mark V is part of GE's successful Speedtronic gas steam turbine management system series. Since the 1960s, this series has been managing heavy-duty turbine systems, and GE has developed more reliable and advanced systems where technology allows. MarkV has triple redundant backup on all key control and protection parameters, including built-in diagnostics and online maintenance functions. Although the DS200ACNAG1ADD product itself can be defined as an ARCNET card, the product with this feature in the initially developed MarkV series will be the DS200ACNAG1 mother printed circuit board that lacks the three important revisions of the DS200ACNAG1ADD product.
The DS200ACNAG1ADD card provides a connection point for ARCNET LAN communication within the MKV system. Due to this specific expected feature in its larger MarkV turbine control system series of automatic drive components, the DS200ACNAG1ADD product requires its own set of functions to be introduced into hardware components and component specifications. The DS200ACNAG1ADD board signal is transmitted through the ARCNET board on the path between the main processor boards (LDCC) to the turbine control operator interface, and then returned. These signals are transmitted through coaxial cables. DS200ACNAG1ADD is a small circuit board with few components. This board has four metal film resistors (R1 to R4), three capacitors (C1 to C3), and one diode. position
Two factories drilled holes on both sides of the circuit board and inserted metal washers into their openings. These two openings are marked as GND1/GND2. Two relays are located near the bottom edge of the circuit board. The top surfaces of both relays contain relay diagrams. A relay diagram is a visual representation of the relay logic that allows the relay to operate. DS200ACNAG1ADD has three communication devices. This includes a vertical pin terminal connector with six pins located in the center of the circuit board, as well as two BNC plugs (right angle, female) with openings located at the top edge of the circuit board. These plugs will accept LAN coaxial cables.
