General Description

The Model 5CX-753 and Model 5CX-754 temperature controllers are economical and versatile units. They can be used as replacement temperature controllers in some lathes and other industrial equipment, either as controllers or as temperature triggered. switches.

The single-pole double-throw (SPDT) relay outputs of the Model 5CX-753 and Model 5CX-754 are rated at 120 VAC, 5 amperes and 10 amperes respectively, and they are ideal for controlling valves, solenoids, and contactors for heating and cooling systems. The availability of both sets of contacts for the SPDT relay makes it suitable for "high" or "low" alarm applications. The addition of transformer input isolation, which permits only low voltage potential on the sensor, affords total input-to-output isolation.

A screwdriverless barrier strip interface provides for easy field installation without special tools. With the ability to control temperatures from -65°C to +550°C in five ranges, this thermistor sensing controller is designed to satisfy most consumer and OEM applications.
 
 

• Economical price.
• Useful for heating, cooling, and alarms in consumer & OEM applications.
• Input to output isolation.
• Sensor Input
• NTC Thermistor over resistance range of 185Kohms to 600 ohms (refer to sensor probe chart in the implementation notes below).
• -65°C to +550°C in five overlapping ranges. Other ranges available (refer to sensor probe chart in the implementation notes below).
• Output
• SPDT relay
• The Model 5CX-753 is UL rated for a 5 ampere load at 120VAC.
• The Model 5CX-754 is UL rated for a 10 ampere load at 120VAC.
• On/Off control mode with typical 2°C switching hysteresis.
• Output circuit fuse protected.
• Set Point
• Temperature adjust: On-board single turn potentiometer which adjusts from 600 to 185,000 Ohms over the temperature range of the sensor. We can supply an R-T curve for the appropriate sensor to help you calibrate the controller set point.
