IND560 Installation Manual
Relay Outputs
The relay outputs can switch up to 250 VAC or 45 VDC voltages at 1A maximum.
The relay outputs are not polarity-sensitive since they are dry contact outputs. An
example of wiring to the outputs is given in Figure 2-35.
Allen-Bradley RIO
Connections to the A-B RIO option board (Figure 2-36) are made using a three-pin
terminal connector on the RIO option.
