Download SDH-4PB Thermostat Specifications
SDH-4PB is a digital temperature controller designed for Heating and/or Cooling.
It has an internal, accurate, programmable thermostat processor, that is self-calibrating and does not require any maintenance or adjustments.
The thermostat controls one on-board relay with contacts rated for up to 30Amp, 250Vac load max. Optionally an internal alarm buzzer or a low power relay can be ordered for special applications to control loads of up to 1Amp, 250Vac max. for instance to activate other external devices.
The high power or the optional low power relay contacts can be wired up to control Heaters, HVAC and other loads like a Fan, Motor, Pump, etc...
The relay contacts can be wired up as completely isolated from the controller's supply, so the supply voltage can be different than the voltages on the load.
In order to switch very high loads, the relay contacts can be wired up to control the coil of an external contactor.
An additional, dry contact input can be ordered for external Start/Stop control switch or other applications, like for instance a water level sensor switch.
Also, an additional, temperature sensor can be installed for special applications like a temperature difference control or to sense the temperature at two separate locations.
The controller is operated and the temperature setpoints are preset by pressing the corresponding keys
on the control panel face. The preset values are stored in internal memory.
A variety of the controller's operating configurations, temperature ranges and limits are also programmable via the face plate keys.
Customized face plates and special, vandal proof push-buttons are available.
The large 3-digit LED display shows temperature preset values, current temperature and other indications of operation. The LED display can be ordered in RED, GREEN or BLUE color.
Note, that SDH-4PB controllers are designed to eliminate almost completely the EMF ( Electro Magnetic Field ) radiation.
