6.3 POWER SUPPLY BOARD

Figure 10: Power supply board

The power supply board provides power to the unit. One of three different configurations of the power supply

board can be fitted to the unit. This is specified at the time of order and depends on the magnitude of the supply

voltage that will be connected to it.

There are three board types, which support the following voltage ranges:

● 24/54 V DC

● 48/125 V DC or 40-100V AC

● 110/250 V DC or 100-240V AC

The power supply board connector plugs into a medium duty terminal block. This terminal block is always

positioned on the right hand side of the unit looking from the rear.

The power supply board is usually assembled together with a relay output board to form a complete subassembly,

as shown in the following diagram.
