The figure on the left uses
the terminal socket of
T37-S30 as an example
to illustrate the output
response relationship
.
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.
With the basic model of T34 (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.
