The new versatile ELK3 and ELK4 series of temperature/process controllers are packed with new features.

The new compact ELK3 series now offers single or dual display controllers both housed in the popular 33 x 75mm size case.

The new range of low cost single- and dual-loop PID auto tune controllers now not only offer programmable input for thermocouple, PT100 or NTC/PTC in one model but also an option for 100-240V AC supply voltage.

Of course, 12 and 24V AC/DC supply voltages remain available.

Other new features include, up to four digitally selectable set points and on many models, up to four SSR or relay outputs.

A sampling rate of 8Hz adds to the ELK3 ability to give accurate process control.

A major new option also offers users who wish to program more than one controller with the same parameters, the ability to quickly and easily download parameters in a matter of seconds, using the ELK3 programming key.

These features can also be found in the ELK4 range of sixteenth-DIN (48 x 48mm) controllers plus the additional benefits of up to three analogue outputs and the ability to control motorised valves.

Both the ELK3 and ELK4 series offer the option of RS485 communications with Modbus-RTU (Jbus) protocol.
