Typical Wiring Diagrams for -T & -B Outputs
B-Type -
840 W maximum. 120 Vac heater. (Non-inductive loads only) For larger loads, replace heater connections
with contactor, as required. Maximum inductive load rating is 3 A at 120 V and 1.5 A at 240 V. The N.C. con-
tacts can be used for cooling.
T-Type -
solid state relay with SPST contacts. The -T units can handle contactors or resistive loads up to 1 A with 10 A
CAUTION
inrush maximum. For -T units use a 1 A, 250 V fast blow fuse.
Possible fire hazard.
Because these
-L Output (Limit Controller)
controls or associated
Wiring can be similar to that shown for "B." The controller's relay is de-energized until the reset button on the
equipment may not
always fail safe, an
front panel is momentarily pressed. The relay will energize if the sensor temperature is below setpoint. The
approved temperature
common and N.C. terminals can be used to indicate alarm condition remotely when wired to lights, bell, etc
and/or pressure
safety control should
be used for safe
operation.
