Process monitoring

The proCHEM series controllers provide a suitable answer to most process monitoring, control or recording requirements.

Dual setpoints are provided. The default set-up for these are as 'too high' and 'too low' control points. The user can also reset them so that they are both 'too high' or 'too low' control points. An example of this type of set-up is where the proCHEM unit has one point set to control the process, and a second point beyond that set to activate an alarm.

Separate LEDs indicate when either of the setpoints has been exceeded. The output relays are rated to 240 V and are fused at 2 A. Higher currents can be switched with an external contactor.

All proCHEM units are easy to install. They are housed in a rugged, plastic case which is non-corrosive, waterproof and dustproof to IP65. All controls can be accessed via the hinged, clear cover. The large LCD is easy to read, even from a distance. The proCHEM series is designed for maximum flexibility. 4-20 mA and 0-1 VDC outputs are provided as standard.
