DES-37-RK-A  is an economic series with basic features, 220 Volt AC/DC Power Supply and Relay output (SSR output must be specified upon order).

(Mounting and panel cut-out dimensions can be found in the product image. The image belongs to the actual product. You can check the supply and other technical details in the specifications tab).

+ Supported sensor models: K type (0-999°C - due to 3-digit display)
+ With next-generation processor technology, it can correct the compensation curve from its own memory.
+ If the connected sensor fails or breaks, the output contact switches to the OFF position.
This model only features heating control. (No cooling function)
CONTROL METHOD: ON-OFF Control Mode
OUTPUT TYPE: Internal Relay
The device has only one active output function. There is no alarm or additional band output.
ANALOG AND PWM OUTPUT: None. If you need analog or pulse output, please check the DSPRO models.
If you need a 2nd relay output for Alarm, 2nd setpoint, or other tasks, please examine our DGS series devices.
ACCURACY: 0.3% FS measurement accuracy
DISPLAY: Single Display, 3 digits, 7-segment LED Display.
While setting the target temperature, it is adjusted via up/down keys on the same screen; it automatically returns to the operating screen after a short while.
Max 50°C Hysteresis range
You can set password-protected limits for user setpoints. For example, if you have a furnace that would be problematic above 140 degrees, you can set upper and lower limits to prevent the machine operator from exceeding the maximum value even if they want to.
Modbus or PC Communication: None. However, you can check our professional series temperature controllers.
RS485 Modbus RTU communication and PC programming are possible. It can communicate with external products such as PLC and HMI. This feature is standard in DSPRO series temperature control models.
This device is designed for basic temperature control in light industrial environments only. It is not certified for use in military, maritime, or medical applications. For detailed information, please visit the Derell Electronics website.
THIS PRODUCT IS MANUFACTURED FOR INDUSTRIAL MACHINE ENVIRONMENTS. IT HAS GALVANIC ISOLATION CAPABLE OF OPERATING ALONGSIDE PRODUCTS WITH HIGH INTERFERENCE EFFECTS, SUCH AS POWER SUPPLIES, FREQUENCY INVERTERS, ETC., IN THE SAME PANEL.

Editor's Note: Friends, the DES series temperature control models were produced for basic ON-OFF applications. It is a "plug and play" controller. It is very easy to use and currently the most economical controller on the market relative to its features. It requires no configuration during commissioning; just provide power, connect the sensor, and you're good to go. I can honestly say I've almost never seen one fail. It has no complex screen structure. Since it has only 2 buttons, all employees can easily use it regardless of their training level. If you have a single-contact output application, there's no need to look for another model (in my opinion).
