Introduction of Shihlin Inverter
Introduction of Inverter
Note: 1. For multi-function control terminals, please refer to
P.80~P.84, P.86
, and for multi-function output
terminals, please refer to
P.40
in Chapter 5.
2. For SS2-TYPE series inverters, the multi-function control terminals have both the sink input mode and
the source input mode. There is a jumper that can be used to alternate between those two modes. If the
jumper is on the left side, the sink input mode is chosen, while the source input mode is chosen if the
jumper is on the right side. Shown as follows:
No matter what kind of multi-function control terminal is used, all of its outside wire arrangement can
be considered as a simple switch. If the switch is ‘on’, the control signal will be put into the terminal. If
the switch is ‘off’; the control signal is shut off.
If the sink input mode is selected, the function of the terminal is active when it is shorted with SD or
connected to the external PLC. At this mode, the current flows out the corresponding terminal when
it is ‘on’. Terminal SD is common the contact input signals. When using an external power supply for
transistor, please use terminal PC as a common to prevent misoperation caused by leakage current.

with open-collector PLC and external power supply
