Connector Details
Figure 51: Power Supply Board Connector Locations
The pin connections for connectors P1 through P4 are as follows:
Pin 1 (NO) = Relay Kn Contacts A Normally Open
Pin 2 (NC) = Relay Kn Contacts A Normally Closed
Pin 3 (COM) = Relay Kn Contacts A Common
Pin 4 (NO) = Relay Kn Contacts B Normally Open
Pin 5 (NC) = Relay Kn Contacts B Normally Closed
Pin 6 (COM) = Relay Kn Contacts B Common
Relay Control (P9)
The P9 connector contains four inputs (with pull-ups) for directly controlling the four
general-purpose relays at connectors P1 through P4. Grounding one of these control inputs
activates the associated relay, and removing the ground deactivates (resets) the relay. The
pin connections for this connector are as follows:
Pin 1 (K1) = Relay 1 control input
Pin 2 (K2) = Relay 2 control input
Pin 3 (K3) = Relay 3 control input
Pin 4 (K4) = Relay 4 control input
Pin 5 (GND) = Connected to Model 6203 chassis ground
Pin 6 (GND) = Connected to Model 6203 chassis ground
