Surace mounting temperature controller TR3645-W

Surface Mounting Temperature Controller

The Model TR3645-W Temperature Controller is designed to be easy to use; accurate; provide control options for simple control applications and a 4-20mA output signal for integration with industrial control options.

The TR3645-W is designed to pair with a 3 Wire PT100 Temperature Sensor to give a measuring and controlling range between - 20°C to + 120°C.

The TR3645 is available as a Din rail mounted unit for mounting in a control panel, or as the TR3645-W in a surface mounting enclosure.

Designed with the operator in mind, the TR3645-W is easy to use and has a large easy to read LCD (liquid crystal display) displaying the measured temperature in °C.

The TR3645-W can be powered from either 115 VAC or 230 VAC 50 / 60Hz.

Temperature Controller TR3645 Dimensions

When the TR3645 is provided in din rail mounting configuration it measures just 105 mm wide x 100 mm high x 58 mm deep.  When supplied in the surface mounting enclosure the unit measures 135 mm wide x 170 mm high and 115mm deep.

When in surface mounting configuration the conductivity controller has a clear door for easy access to the simple to use controls, allowing the operator to calibrate the instrument or set the two set points from the front panel.

The values of the set-point is easy to determine using the front mounted potentiometers.  By selecting a value at which the set-point should operate and either high or low level operation to engage the set-point.  The system has a set-point LED to illustrate the relay state and for checking the relays during setup or commissioning.

Temperature Controller TR3645-W Setpoint with On/Off Control Relay

The TR3645-W has an easy to programme On/Off control setpoint with an adjustable time delay of up to 40 seconds before the relay operates. The relay co-operation can be selected for either High or Low operation via a control switch.

When the setpoint is configured for use under low operation, then when the monitored temperature value is lower than the setpoint value, the LED is lit and the corresponding relay is activated.  If the relay has the delay function activated then the timer will be called until the relay is activated.

For use under high operation, then when the monitored temperature value is higher than the setpoint, the LED is lit and the corresponding relay is activated.  Again, if a delay has been assigned to the relay then the relay will wait until this delay has expired, before activating the relay.

As the TR3645-W is an easy to use temperature controller with excellent control options, it makes an excellent choice of cost effective temperature controller for many processes, including simple engagement and disengagement of a heater, alarm circuitry or for integration into larger systems where temperature is measured or controlled.

TR3645-W easy to use Conductivity Controller with 4-20mA Output

The TR3645-W surface mounting temperature controller has an industry standard 4-20mA output.  This 4-20mA output can be used with a variety of control equipment, including PLC's and Chart Recorders.  The 4-20mA output in this instrument is non-expandable, meaning that it corresponds precisely to the measured range of the instrument selected.
