Wiring Graph for Thyristor Trigger Output
Note: It is recommended to use the power module, which includes 2 pair of SCRs and diodes. Compared to TRIAC, it is more reliable and consumes
less trigger current.
Note: The compensation
wires for different kinds of
thermocouple are different,
and should be directly
connect to the terminals.
Connecting the common
wire between the
compensation wire and the
terminals will cause
measurement error.
Note: The graph suits for upright
intruments with dimension A or E
For instruments with dimension
F, just clockwise rotate the graph
90 degree and the terminal
numbers keep the same.
