How to change the interior switch when using 1~5V input
①Remove the jumper cover
on the underside of the K30,
or remove the rear case.
②Detach the jumper using
tweezers and move it to the
1-2 pins to the left.
③Once this has been com-
pleted, put the jumper
cover back on, as shown
on the picture above.
※When using 1~5V input (30),
the interior jumper switch must be
relocated.

Summary and explanation of output settings
Relay output of ON/OFF control [ Output setting number : 0 ]
This is a simple on/off control, mainly used to control cooling devices.
SSR output of PID control (Voltage pulse) [ Output setting number : 1 ]
This is the most widely used setting, and the default value at the point of manufacture.
SCR output of PID control (4~20mA current output) [ Output setting number : 2 ]
This setting is used mainly with thyristor power regulator (TPR) modules, and is capable of
precision control.
Relay output of PID control [ Output setting number : 3 ]
This is the most cost-efficient method of implementing PID control and is used mainly with
magnetic switches (electric switches). However, it may wear the contact point, and is
difficult to use in places that require fast response.
Alarm output of K34(48´48) basic type(S00)
With the basic model of K34 (48x48), caution is required when using it alarm output. When control output is being used as a relay, the
alarm output will be SSR output (voltage pulse). In this case, use SSR or alarm option (S10, S30) enabled models.
