Description
The EKMG sits in the connection head and passes temperature on over IO-Link instead of a current loop. It measures either with one Pt100 in three-wire connection over −200 to 800 °C or with a thermocouple of type J, K or N, together covering −200 to 1372 °C. The amplifier resolves 16 bit and adds at most 0.02 % of the nominal range to the sensor error; the response time is 20 ms, the filter setting 25 s. Supply is 24 V DC with less than 30 mA in normal operation and at most 130 mA in total when the switching output is loaded; reverse polarity does not destroy the device, and input and output are isolated with 1 kV AC. The black PA66 case measures Ø 45 × 23 mm, weighs about 35 g and is rated IP20. On request the device comes with an aluminium die-cast connection head of form B.
