Input Circuits
Either positive or negative poles of the power supply can be connected to the
common (COM) terminals, enabling connection of both PNP (negative com-
mon) and NPN (positive common) inputs.

Input devices
The power source of the SP10 for external supply is rated at 0.1 A, 24 VDC
max., and the power source of the SP16 and SP20 is rated at 0.2 A, 24 VDC
max. The input circuit consumes about 7 mA (typ. at 24 VDC) per input point.
Transistor outputs with a current consumption up to 0.2 A can be used with
the SP10, and a current consumption up to 0.32 A with the SP16 and SP20.
Relay contact outputs require a current of 0.013 A each, so when all of the
relays are ON, the external power supply capacity is 0.1 A for the SP10 and
0.2 A for the SP16 and SP20. When using the SP10 as the power source for
