Product description
Discover the GTE-1-60-DM, a temperature-based fan speed controller designed for monophasic voltage-controllable motors.
Ideal for glasshouses, it offers versatile fan speed control based on measured temperature, ensuring optimal environmental conditions.
With Modbus RTU integration, you can remotely or automatically adjust settings.
When the measured temperature falls below the setpoint, the fan operates at low speed; when exceeded, it accelerates proportionally.
Operate the controller standalone with manual control or connect it to a computer using Sentera’s 3SModbus software or the Sensistant configurator for remote Modbus control.
Additionally, connect to SenteraWeb for Internet-based control.
Key features include PT500 temperature probe input (pre-wired for DT version), temperature setpoint potentiometers (15—35 °C), and adjustable minimum speed. Internal trimmer allows for maximum speed adjustment with customizable hysteresis and proportional range.
Housed in a reliable RABS V0 grey (RAL7035) enclosure, the GTE-1-60-DM ensures precise and reliable performance.
Technical specifications encompass a 230 VAC ±10 % / 50—60 Hz supply voltage, 6 A maximum motor current, Vmin adjustable (80—160 VAC) via potentiometer, and Vmax adjustable (170—230 VAC) via internal trimmer.
Additional specifications and description
Temperature based fan speed control
If you need versatile fan speed control in your glasshouse, this is what you need. This device is intended for monophasic voltage controllable motors and control is based on the measured temperature. What makes it perfect for your contemporary hothouse is the fact that it features Modbus RTU. This means you can control the environment parameters remotely or automatically based on the settings you have applied. When the measured temperature is lower than the temperature setpoint, the fan runs at low speed. When the selected temperature is exceeded, the fan accelerates. The higher the measured temperature, the higher the fan speed.
Standalone or computer controlled
The controller can be used both as a stand-alone unit or in conjunction with a computer and operated by Sentera’s 3SModbus software or the Sensistant configurator. When used stand-alone, its jumpers need to be set to the desired values. This means the device is controlled manually.
When used in Modbus mode, its parameters are set via Modbus RTU. This means the device is controlled remotely via a PC, so there is no need to set the jumpers, i.e. they can remain in their factory set positions.
The device also features a further option – you can connect it to SenteraWeb and control the GTE via the Internet.
What is Modbus RTU communication
All settings of this fan speed controller can be adjusted and monitored via Modbus RTU communication. The output voltage can be set locally via the built-in potentiometer or remotely via Modbus RTU communication. All you need to do is download our free 3SM Software from our website and you get the motor control type you wish – manual or digital, i.e. local or remote!
Accessories
A PT500 temperature probe needs to be connected to the controller in order to measure the temperature in the relevant area. Based on the measured temperature the controller works toward reaching the setpoint selected via the potentiometer on the enclosure or via Modbus (bear in mind that Modbus mode overrides manual control).
Control more than one fans
You can connect several motors to the controller as long as the current limit of 6 A is not exceeded. In this case all of them will run at the same speed.
Unregulated output
The GTE features an unregulated output, called so because it is either ON (230 Volt) or OFF (0 Volt). If the supply voltage is connected to L and N, the unregulated output is active while the motor is in operation. You can use this output to control external devices (2 A maximum current), for example a run-indicator or a damper, etc. This means that while the fan is working, the damper will be open or the run indicator will be on. When its stops, the damper will close and the indicator will be off.
Solid enclosure
This controller is the result of many years of experience in greenhouse air extraction combined with innovative electronics technology. To make the device reliable and safe we manufacture the enclosures in our own factory. This enclosure is made of high-quality R-ABS, V plastic. This material is flame retardant, very though and offers good protection against impacts. Its ingress protection class is IP54 against dust, dirt and water.
