: I is subject to current limiting at the moment. The current limitation cuts in at 25 mA. Short circuit at
load impedance <100 Ω.

Analog electronics module 4 AI I 4WIRE HART
Order number
6ES7134-7TD50-0AB0
Properties
● 4 inputs for connecting HART field devices, 4-wire transducers (standard applications)
● Configurable input range: HART, 0 to 20 mA, 4 to 20 mA
● Resolution 12 bits + sign
Note
If you connect up to four sensors to the electronic module, you must connect the "-"
measuring connections of the sensors one below the other or connect each with
equipotential bonding using wires. The wires must be arranged so that they are not liable
to interrupted.
If you connect up to 2 sensors to channel 0 and channel 2 (channel 1 and 3 unconnected),
no further measures are necessary.
