CONNECTIONS

Referring to the following descriptions of terminals, complete

connections before you turn the power ON.

4

Auto-zero input terminal:
Sets the analog output voltage to 0 V when this terminal and
GND terminal (5) are short-circuited. (When current output is
used, the output current is set to 4 mA.) (See p.9.)

6

NPN output (Disconnection alarm output) terminal:
Outputs a signal when the sensor head cable is disconnected.

8

Analog voltage output terminal:
Analog voltage of 0 to 5 V relative to full measuring range is
output.

9

Analog current output terminal:
Analog current of 4 to 20 mA relative to full measuring range is
output.

A

& B Interference suppression terminals: (See p.12.)

The interference suppression function is not available with the
EX-500(W) series (compliant model with the EMC directive (CE
marking)). If you want to use the function, be sure to check
whether the operation complies with the EMC directive on your
account.
