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 o
f
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.
