Our Digital Temperature Indicators feature a 4-digit 20 mm high LED display that can display 2 parameters, 96 x 48 mm DIN housing, inputs from 0 to 1 V, 0 to 10 V or 0/4 to 20 mA. This offers an indicator for supplying a DC voltage of 2 two-wire transmitters. The display is automatically switched in a cycle of about 5 seconds on the two measures. In combination with humidity temperature transmitters PFT 22, these indicators can be used to indicate two metrics. The supply is achieved by a 230 V AC or 24 V AC or 24 V DC.
