Short description of the expansion module AM2 PT100

The analog expansion module AM2 PT100 is equipped

with two inputs, each one for connecting a Pt100 ther-

mocouple.

The analog expansion module AM2 PT100 converts the

resistive value of a connected Pt100 thermocouple to a

temperature measurement range of –50 °C ... +200 °C

with a resolution of 1000 measuring steps.

The analog expansion module AM2 PT100 is compati-

ble with all LOGO! devices (as of ...–0BA3).

Options of connecting a Pt100 thermocouple You can connect a Pt100 thermocouple to the module in 2- or 3-wire technique. When you select the 2-wire technique, you must jumper terminals M1+ and IC1 or M2+ and IC2. Measurement errors due to measurement cable resistance will not be compensated with this type of connection.1 W cable resistance is proportional to a measurement error of +2.5Ă°C. With 3-wire connection, the influence of the cable length (resistance) on the measurement result will be suppressed.

Note Operation of the LOGO! expansion module AM2 PT100 on an ungrounded (floating potential) power supply may result in severe fluctuation of the displayed temperature value. In this case connect the negative output / power supply ground to the shielded measurement cables of the thermocouple. Programming the AM2 PT100 under LOGO!Soft Comfort V3.x You can program the expansion module AM2 PT100 as usual under LOGO!Soft Comfort => Version 3.0. As of Version 3.
