12.14 2AI RTD High Feature Analog Electronic Module
(6ES7 134-4NB50-0AB0)
Order Number
6ES7 134-4NB50-0AB0
Features
S 2 inputs for resistance thermometers or resistance measurement
S Input ranges
– Resistance thermometers: Pt100; Ni100; Ni120; Pt200; Ni200; Pt500; Ni500;
Pt1000; Ni1000; Cu10;
resolution max. 15 bits + sign
– Resistance measurement: 150W; 300W; 600W; 3000W; PTC;
resolution max. 15 bits
S Automatic compensation of line resistances in the case of a three-conductor
connection
S Temperature coefficient can be parameterized for resistance-type sensors
S High degree of accuracy
S Isolated from the load voltage
S Linearization of the sensor characteristic curves
S Parameter length 7 bytes
S Permitted common-mode voltage 5 VACss
S Recording of reference junction temperature (together with the 2AI TC Standard
electronic module)
S Compatible with the 2AI RTD Standard (6ES7 134-4JB50-0AB50)
Note
The EM 2AI RTD High Feature can replace a 2AI RTD Standard in an existing
system.
S
The wiring does not have to be changed. The additional bridges on the terminal
module of the 2AI RTD Standard do not have to be removed.
S
The configuration (in HWCONFIG or the DDB file) does not have to be
changed. Only the new functions of the 2AI RTD High Feature cannot be
parameterized in this instance.
