WARNING
UNINTENDED EQUIPMENT OPERATION
Use the sensor and actuator power supply only for supplying power to sensors or actuators connected to the module.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
CAUTION
LOSS OF INPUT FUNCTION OR OUTPUT FUNCTION
Install the correct type of power supply fuse with the correct rating.
Failure to follow these instructions can result in injury or equipment damage.
Wiring a single power supply: 
1
24 Vdc power supply SELV 
2
Fast-acting fuse 2 A (to protect against overvoltage greater than 36 Vdc) 
3
Actuator for the Q1 output of channel 1 
4
Actuator for the Q0 output of channel 0 
5
Supply active pickup (APU) sensors interface 
6
Supply outputs interface 
7
Internal wiring
NOTE: To separate supplies for inputs and outputs, connect a second power supply on pin 10 and pin 9.
