TAMP4-G3 with direct address-election

Multiplexer TAMP4-G3

Article Number: 


At the temperature multiplexer TAMP4-G3 up to 4 PT100 sensor can be connected. These are operated as a 2-wire with 1.5 mA constant current.

By a master control can be one of 4 inputs are activated and as an analog signal at the output of AA (4..20 mA) is output. The active input is selected by two address bits according to the formula:


Input channel = 2 * bit1 + 1 * bit0


The connections are made via plug-in screw terminals up to max. 1.5 mm².

TAMP4-G3 is contactless and maintenance free. It must be protected from moisture and heavy soiling.
