Range card selection for analog modules of Siemens S7-300PLC - Database & Sql Blog Articles

Q: The analog module in the hardware configuration, when selecting the measurement, there are E, 4DMU, 2DMU, I understand how to use, and R-4L, RT, TC-I, TC-E, TC-IL , TC-EL, what do you mean by these? How to use it? I also know the meaning of each word in the following English, but I don't know what the description means? Thank you for your reply.

Question added: There is also the address of the analog output module, such as AO4x12Bit, the address of this module is from 512--519, those points belong to 512, those points belong to 513, those are connected to the power supply, Thank you

A: E voltage
4DMU current 4-wire sensor
2DMU current 2-wire sensor
R-4L resistor 4 wire terminal
RT resistance (thermal, linear)
TC-I thermocouple (internal compensation)
TC-E thermocouple (external compensation)
TC-IL thermocouple (internal compensation linear)
TC-EL thermocouple (external compensation linear)

Terminal 1 is connected to L+24V+
20 connected to M0V
34 connected together + corresponding to PQW5122 line system without compensation for line resistance
56 together -

34 received the site to receive a corresponding + corresponding PQW512 compensation for the line resistance
45 received the scene to receive a corresponding -
