General Description

The Model 5CJ-010 and Model 5CK-010 are On/Off temperature controllers that use thermocouple sensors. Output is through an SPDT relay rated at 5 amperes @ 120 VAC.

The 5CJ models use Type J thermocouples, while the 5CK models use the Type K thermocouples. The type K thermocouple senses higher temperatures (0° to 1250°C) than the type J (0° to 750°C).

These units have 3°C switching hysteresis, nominal.

(Units which are similar but which use Proportional control through a Triac are the models 5CJ-020 and 5CK-020.)
