Figure 3-10. GPI Input
Fig. 3-11: GPI Output andAlarms
Power applied to the inputs can be from 5 to 24 VDC, and less than 30 mA. Typically, 5 V at 1 mA.
Loads for the outputs can be larger:
Max current: 1 A
Max voltage: 125 VAC, 110 VDC.
Max capacity: 62.5 VA, 33 W.
Rated loads: 1 A at 30 VDC; 0.3 A at 110 VDC; 0.5A at 125 VAC.
