Temperature measurement amplifier

The universal multi-function display unit meets demanding requirements and offers indication and re-transmission of the process value in current, voltage, potentiometer, resistance, and thermocouple signal. Flexibility of the TMV 4 can accomodate a variety of applications combined in one unit. It has up to two freely configurable limit value contacts and offers the choice of displaying two different values. Other outputs include optional analog current or voltage outputs, including RS 485 interface for serial communication. Easy programming via 5 keys simplifies the operating procedures and the password protected access control ensures a tamper-proof operation of the instrument.
