Electrical connection
5.1 Device connector
Connector A · Power supply
The same pair of conductors transmit the 4
to 20 mA measuring signal and the required
power supply (U
B
= 12 to 36 V) for the two-
wire transmitter.
The Media 6 is connected over a
DIN EN 175301-803 connector, type A,
4-pole.
Two-wire connection for 4 to 20 mA current

Rated power supply U
B
= 24 V DC. Taking
the resistance of the supply leads directly at
the terminals of the connector into account, it
must be between 12 and 36 V DC.
Optionally, battery operation possible with
9 V DC power supply
Connector B · Limit contacts/pulse output
Connection of two software limit contacts in
type of protection Ex ia IIC for control circuits
according to NAMUR on switching amplifier
according to EN 60947-5-6

i

Media 6 Z includes only one software limit
contact (alarm 1) and one pulse output (in-
stead of alarm 2/contacts 3 and 4), which is
proportional to the tank capacity, to control
an external counter.
Test connection
Connect an ammeter to the test ter
and – to test the output signal during cali-
bration. The output signal of the two-wire cir-
cuit is not interrupted during this procedure.
Make sure that the ammeter provides a load
of < 0.4 V DC for the test connection.
