• The GR3017G200 is a connection / interface board used inside the Gearbox / Transceiver of SAM radar systems (e.g. in SAM Electronics “Radar 1100” / related models).

• In the technical manual for the Radar 1100 series, it is called the Connection Board (GR3017G200), installed in the gearbox or in bulkhead housing depending on configuration (Version A: inside gearbox; Version B: additionally mounted in bulkhead)

• Its role is to interconnect / route wiring between system components: motor, heating, start units, pulse generators, performance monitor, headmarker, etc.

So in effect, it is not a power supply per se, but a junction / interface board within the radar / transceiver structure.

• The connection board has multiple pin / terminal blocks like J8, J2, J5, J6 etc., used for routing signals (24 V ON/OFF, pulses, VEE, ground, CAN bus, etc.)

• It connects to the Headmarker, Performance Monitor / Pulser, Start Unit, Motor / rotation control and other subsystems.

• It contains fuse carriers (for replacing fuses) accessible via terminal blocks.

• In wiring configurations, shorting bars / links are used on this connection board to route supply in different versions (e.g. in 1-phase / 3-phase supply modes)

• The manual lays out “TB1, TB3” terminal blocks in the connection board, and mapping to functions (like +24 V, ON/OFF, pulse, etc.)

• critical to the signal & power distribution inside the radar’s transceiver / gearbox.
