4-20mA digital potentiometer with wide voltage supply range and two digital inputs (+/-), TENSE (Made in Turkey)

The Tense PTM-02 is a microprocessor-based digital potentiometer designed to produce an analog output of 4-20mA for use in industrial automation and control systems. It is manufactured by Tense Electronics, a Turkish company. 

Key Features

• Analog Output: Provides a precise 4-20mA analog current output (or 0-10V DC in PTM-01).
• User Control: Output values can be adjusted via up/down push buttons on the front panel or through external up/down digital inputs (dry contact only).
• Display: Features a bright and clear 4-digit, 7-segment LED display.
• Programmable Limits: The user can set adjustable upper and lower limits for the analog output and the set value.
• Wide range voltage supply.
• Memory: Settings are stored in EEPROM memory to retain them in case of power failure.
• Design: Compact, space-saving design intended for DIN rail or permanent panel installation.
• Applications: Ideal for applications such as motor speed control (VFDs), dimming systems, and PLC analog input management. 
• Password protection.
