Kilnminder 4.E Programmable Controller

Run your burnout cycles at night, while you sleep. It's just like having a second shift, without the extra overhead! 

• 10 pre-programmed kiln heating programs. (User can edit)

• 99 user-programmable kiln heating programs.

• 1 to 20 (user adjustable) stages per kiln heating program.

• Each stage has a programmable temperature between 100°F and 2450°F (38°C and 1344°C).

• Each stage has a programmable ramp time between 0 to 42 hours in adjustable in 10-minute steps.

• Each stage has a programmable dwell time between 0 and 42 hours in adjustable in 10-minute steps.

• Delayed start from 0 to 85 hours adjustable in 20-minute steps.

• Elapsed time display during kiln heating program.

• Auto-tuning feature automatically adjusts power to the oven to prevent temperature overshoot or undershoot.

• Security feature allows user to lock some or all programs, which can only be changed by authorized personnel.

• Dual-thermocouple capability. An optional secondary thermocouple can be attached to engage automatically if the primary thermocouple fails.

• 8 option settings allow you to customize your Kilnminder 4.E to run in sync with your oven type.

• Digital temperature readout in °F or °C.

• High temperature safety shutoff relay independent of control relay.

• Power outage return using internal capacitor. No battery to replace.

• Enhanced reliability and longevity of kiln heating element control relay.

In 2023 the manufacturer upgraded this unit to enhance the reliability and longevity of the electromechanical relay.  So now the kilnminder times the relay switching so it occurs at precisely the moment the line voltage passes through zero volts.  It also alternates between closing into a positive going cycle and a negative going cycle.  Doing this dramatically reduces the buildup of metal deposits on the relay contacts.   They also made the push buttons slightly larger and gave them a better tactile feel and upgraded the feet on the unit to higher quality, more crack-resistant versions.
