2AI RTD Standard analog electronic module
(6ES7 134-4JB50-0AB0)
Order number
6ES7 134-4FB50-0AB0
Properties
•
2 inputs for resistance thermometer or resistance measurement
•
Input ranges:
-- Resistance thermometer: Pt100; Ni100; resolution 15 bits + sign
-- Resistance measurement: 150
Ω
; 300
Ω
; 600
Ω
,
resolution max. 15 bits + sign
•
Isolated for load voltage L+
•
Linearization of the sensor characteristic curves
Terminal assignment
The resistance thermometer/resistances are measured in 4-wire connection. A
constant current is fed to the resistance thermometers/resistances through the
terminals I
C
+ and I
C
--. The voltage at the resistance thermometer/resistance is
measured through terminals M + and M --. This provides a high degree of precision
in the measurement results with the 4-wire terminal.
With the 2-3-wire terminal appropriate bridges are required on the module between
M+ and I
c
+ or M-- and I
c
--. However, this involves a loss of precision in the
measurement results.
