Z Series Controllers - Ascon Tecnologic Digital Electronic Thermo Controller with Defrost Function

The Z31 is a digital electronic thermocontroller with a single input for PTC or NTC temperature sensors and a robust 16A-rated relay output.

The Z31 temperature controller is typically used for cooling applications that require on/off switching mode and defrost control by stopping the compressor at defined defrost intervals. An internal buzzer is also available for audible alarm annunciation.

The Z31S features the "Sensitive Touch" capacitive keyboard. This innovative patented system has no moving parts to wear out, is impervious to dust and liquids and has a flat surface that is easy to clean, making it a perfect instrument for the food industry.

Features:

• 1 input for PTC or NTC temperature probes
• 1 Relay output SPST or SPDT, 16A/250VAC (AC1)
• Configurable defrost cycles by stopping compressor
• Range -50 to 150°C
• On/off control
• Password parameter protection
• Keyboard lock function
• Optional alarm buzzer
• Optional "sensitive touch" keypad featuring no moving parts and high resistance to liquids and dust
• Save, transfer and store instrument configuration on A01 programming key as well as store configuration to PC
