• Automatic compensation of wire resistances with 3-wire connection.
• Configurable temperature coefficient with resistive sensors
• High degree of accuracy
• Isolated for load voltage
• Linearization of the sensor characteristic curves
• Parameter length 7 bytes
• Allowable common-mode voltage 2 VACss
• Recording of the reference junction temperature (in connection with the 2AI TC
Standard electronic module)
• Compatible with 2AI RTD Standard (6ES7 134-4JB50-0AB0)
Note
The 2AI RTD High Feature electronic module can replace a 2AI RTD Standard in
an existing system.
Changes to the wiring are not required. The additional bridges on the 2AI RTD
•
Standard terminal module need not be removed.
No change in the configuration (hardware or GSD file) is required. In this case
•
only the new functions of the 2AI RTD High Feature are not configurable.
