THERMOSTAT AND TEMPERATURE REGULATOR

HD4030 Digital Temperature Regulator Thermostat with Display 48x78, Pt100 Sensor.
Measuring range -50°C +150°C. Resolution 0,1°C. Proportional band ±1,5°C ... ±15°C.
Relays 5A 220V resistive. Power supply 24Vac/dc, on request 110…230Vac/dc.
HD4030BM Digital Temperature Regulator Thermostat with Display. 48X78, Pt100 sensor.
Measuring range -50°C…+150°C. Resolution 0,1°C. Dead band 0.6...6°C.
Output with two independent relay 5A 220V. Power supply 24Vac/dc, on request 110…230Vac/dc.

The regulation characteristic is of the PID type; the proportional band may be set at the rear of the thermostat by means of a single-rev trimmer in the range ±1,5°C ±15°C.
The outputs have relays with contacts protected by VDR.
The state of the relays is indicated by two LED's on the front. 
The desired working temperature (set point) may be set by means of a 15-rev knob on the front panel.
The instrument has a Pt100 Platinum temperature sensor (100ohm at 0°C).
With the three-wire connection, the line resistance is automatically compensated up to 5 meters.
