Wiring of Digital Inputs
There are two digital inputs of wet contact in the standard DPMS XPQ. The
terminals of the two digital inputs are DI1+, DI1- (15, 16) and DI2+, DI2- (17,
18). Additional two digital inputs are optional. The terminals of the two additional
digital inputs are DI3+, DI3-(25, 26) and DI4+, DI4-(27, 28). The circuit drawing
of the digital input is simplified in fig 2.27.
fig 2.27 Digital Input Circult of the DPMS XPQ
The auxiliary power supply for the digital input is 12~24Vdc. If the
connection wire is too long, a relative higher voltage should be adopted. The
current in the loop line should be 10mA~15mA, and the Max current is 30mA.
A DI auxiliary power supply (optional) is provided for the convenience of
field use. The voltage of the DI auxiliary power supply is 15Vdc (1W). The wiring
terminals are V+ and V- (29, 30). This power supply can not be used for any
other purpose.
The 4 DIs with the auxiliary power supply is in fig 2.28. The wire for digital
input should be between AWG22 (0.5mm
2
)~ AWG16 (1.3mm
2
).
