Temperature Measurement


Three-output temperature controller

August 2006 Temperature Measurement

The Toho J4 (48 x 48mm) microprocessor-based digital temperature controller is a powerful and compact temperature controller with three outputs.

The local distributor, Temp-Tek, claims that most temperature controllers of this size offer only one or two outputs. The J4, and its bigger brother the J5, offer the ability to control devices such as a motorised valve that needs a full PID function in both directions or wrapping and packing machines that need interlocks to start at certain temperatures as well as to control heater banks and additional fans.

This inexpensive controller has all the internally stored software to allow a customer to choose between these the two above mentioned applications.

The J4 and J5 are complete with an internal timer and Toho's advanced self tune facility that allows the controller to continually update its PID settings.
