9. Single Phase 3 Line (Wiring mode setting 3LN, 3CT)
Wiring of Digital (Switch Statues) Input
There are two digital input of wet contact in standard
Ai
205. The terminals
of the two Digital input are DI1+, DI1- (15, 16) and DI2+, DI2- (17, 18). Additional
two digital inputs are optional. The terminals of the two additional are DI3+, DI3-
(25, 26) and DI4+, DI4-(27, 28). The circuit drawing of the digital input is simplified
as Fig. 2.27.
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 less than 10mA-15mA, and the Max current is 30mA.
