IE3312 Extension Box
The IE3312 analog input module permits four thermocouples to be directly connected. The module’s circuit can operate thermocouple sensors using the 2-wire technique.
Number of inputs: 4
Connection method: screw type M12, 2-wire connection for thermocouple
Sensor types: types J, K, L, B, E, N, R, S, T, U (default setting type K), mV measurement
Measuring range: depending on sensor type; preset value is type K, -100…+1370 °C
Resolution: 0.1 °C per digit
Measurement error/ uncertainty: < ±0.5 % (relative to full scale value)
Conversion time: approx. 250 ms, configurable up to 70 ms
Nominal voltage: 24 V DC (-15 %/+20 %)
Input filter: 5 variations, configurable
Current consumption: from US (without sensor current) 40 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
