3.5 I/O-DC Module 
The I/O-DC Module (see Figure  3-8) can control up to 8 DC Latch Solenoids. The 
operating voltage may vary from +2 to +49 volts (Defined by Site Configuration definition, 
Programming Tool Box). The I/O-DC Module also responds to back indication signals from 
8 different field input sensors. 
The I/O-DC Module should be located in the slot designated by the Site Configuration 
application (Programming Tool Box). 
The Special Features of this Module are: 
•  Output short circuit protection. 
•  Automatic solenoid detection. 
•  Software controllable output voltage to operate DC solenoids (+2 to +49 VDC).
