VC1-0808MAT1 adopts RS232 and Mini DIN8 socket, 1 channel of RS485 and Type-C USB
interface. The right expansion module interface is used to connect the expansion module, the left
one is used to connect the expansion communication module. There are two options for the mode
switch, ON/OFF, and one RS485 terminal resistor with a resistance of 120 Ω (DIP No. 1).

3 Switch Input and Output Characteristics

3.1 Input Characteristics and Signal Specifications

The PLC provides the "S/S" port for selecting the signal input mode, which can be set as source-
type or sink-type mode. Connecting "S/S" to "+24V" means users select the sink-type mode, and
then an NPN-type sensor can be connected.
