The 1734 OB8 wiring diagram is arranged as follows:
Power Supply Wiring
The 1734 OB8 requires a 24V DC power supply. The power supply wiring involves connecting the positive and negative sides of the power supply to the module’s power terminals.
Output Wiring
The output wiring involves connecting the load to the module’s output terminals. The module’s outputs are configured as either sourcing or sinking outputs. If the output is sourcing, the positive side of the load is connected to the output terminal. If the output is sinking, the negative side of the load is connected to the output terminal.
Each output terminal is identified by a unique number. The wiring diagram provides the wire color for each output terminal to assist in identifying the correct terminal.
Grounding
The 1734 OB8 must be properly grounded to ensure proper operation of the system. The wiring diagram provides a grounding symbol to indicate where the ground wire should be connected.
