●Mount the contact protective element that conforms to buffer relay.
MOS relay is broken, if a signal exceeding the contact capacity is
applied even momentarily.
●The mounting position is on coil side (diagram ‘a' of clause 2
‘Connection’ of section 5.5) of the buffer relay that effectively lightens
the load and thus prevents malfunctioning.
(1) Coil rating … Within the contact capacity of output terminals
(2) Contact rating ... Two times or more than the load current
A coil surge absorption element built-in type relay is recommended.
Mount an additional buffer relay if a buffer relay satisfying the load rating
is not available.
Mount this element when buffer relay of surge absorption element built-in
type is not available.
This element is generally composed of C·R (condenser + resistor).

4) Connection of RS232C/485
Connect to the PC using protocol converter (our model:SC8-10).There are only 3 signals viz. SD, RD
and SG between protocol converter and PC and control signal is not used. Wiring process of connector
similar to “(3) High order communication for RS-232” on the previous page, is necessary.
Installing termination resistance
Notes
To ensure the transmission of communication data of RS232C or RS485, termination resistance is
installed in both the terminals of transmission route. When protocol converter (SC8-10) takes both the
terminals of transmission circuit, short ④ and ⑤. By doing this termination resistance is inserted.
