Safety Wiring; I/O Point Wiring - Delta DVP-ES2 Instruction Sheet

 Safety Wiring
In PLC control system, many devices are controlled at the same time and actions of any
device could influence each other, i.e. breakdown of any device may cause the
breakdown of the entire auto-control system and danger. Therefore, we suggest you
wire a protection circuit at the power supply input terminal. See the figure below.

 I/O Point Wiring
There are 2 types of DC inputs, SINK and SOURCE. (See the example below. For
detailed point configuration, please refer to the specification of each model.)
