5.3 Current Output Module
The module EM002 can be installed to obtain a current output.
The pin assignment is as follows:
output current pin 19a . . . . . . . . . . . . .
supply zero pin 20a . . . . . . . . . . . . . . .
The power range is switched by the DIP switch 24/5.
Output current source S24/5
+4...+20 mA
+20 mA (ex-works setting)
When using an EM002, current and voltage outputs are not aligned to each
other. The required fine calibration can be carried out from the front panel (as
described in chapter 3)
5.4 Safety Barriers for use in Hazardous Areas
For transducer operation in potentially explosive atmospheres the safety barri-
ers SD01 are used conforming to the protection classes (EEx ib IIC) accord-
ing to VDE0171, EN 50 014 and EN 50 020 (see data sheet).
5.5 Additional Units
The following additional cards are available for the measuring amplifier ME30:
– automatic zeroing unit NE02
– peak / last value memory SE03
– limit switch GE04
