IE3112 Extension Box
The IE3112 analog input module handles signals in the range from 0/4 to 20 mA. The input current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, electrically isolated, to the higher-level automation device.
Number of inputs: 4
Input connections: M12, screw type
Signal voltage: 0/4…20 mA
Internal resistance: 80 Ω measuring shunt
Common-mode voltage UCM: max. 35 V
Resolution: 16 bit
Measurement error/ uncertainty: < ±0.3 % (relative to full scale value)
Conversion time: 250 ms, configurable to 5 ms
Nominal voltage: 24 V DC (-15 %/+20 %)
Input filter: configurable
Sensor supply: from load supply voltage UP
Current consumption: from US (without sensor current) 55 mA
Power supply connection: feed: 1 x M8 male socket, 4-pin; downstream connection: 1 x M8 female socket, 4-pin
Bit width in the process image: input: 4 x 16 bit data (4 x 8 bit control/status optional)
Electrical isolation: channels/control voltage: 500 V, between the channels: no, control voltage/fieldbus: yes, via IP-Link
Operating/storage temperature: 0…+55 °C/-25…+85 °C
Vibration/shock resistance: conforms to EN 60068-2-6/EN 60068-2-27
EMC immunity/emission: conforms to EN 61000-6-2/EN 61000-6-4
Protect. rating/installation pos.: IP65/66/67 (conforms to EN 60529)/variable
Approvals/markings: CE, UL
