PID Temperature Control  - 3 Setpoint  HP56
2 relay and solid state relay output   

General Description

HP56 is a 3 set point, temperature control designed specifically to allow easy change over between different settings.
It has 2 relay outputs and either a solid state drive or proportional voltage output.

Main Features

For the user, separate temperatures may easily be set and then selected by a separate switch.
(Set values can be secured from unauthorised tampering by closing a pair of contacts on the rear terminals enabling 'key lock' security)
Alternatively, an external timer could be used to initiate the different  temperatures automatically.

20mm display indicates temperature in C or F.
LEDs indicate condition of programme, and output relay.

Additional Features:


Programmable  on/off or PID control,  Relay/Solid State Relay/ 0/10V / 4-20mA outputs.
Tamperproof locking by linking contacts at rear allows 'key lock' security of settings.
Temperature limits  Maximum and minimum temperature range can be set.
Self tune for optimal setting of PID parameters selectable for continuous operation.

Removable terminal strips for easy connection/disconnection
Adjustable 'ramp rate' to each new set point ensures smooth transition between levels.
2x auxillary relays can be used for high and/or low temperature alarms which can be set individually to either 'track' the set point or to have an absolute setting.
Sensor input programmable for thermocouples  J,K,R,S.T,N -250/+1700 Deg.C or F,  Pt100 -200/+550 Deg.C or F
Programmable for 1,2 or 3 set points.
