Outputs
5.4.1
Analog output
This output can be used either as a 0/4 to 20 mA current output or as a voltage pulse output.
The output is galvanically isolated. Terminal assignment, (→ 20).
5.4.2
Relay
The two relays can be switched in case of fault messages or a limit violation.
Relay 1 or 2 can be selected under

Pulse output
Voltage level:
• 0 to 2 V corresponds to Low level
• 15 to 20 V corresponds to High level
Maximum output current:22 mA

Communication
The USB interface is always active and can be used independently of other interfaces.
Parallel operation of multiple optional interfaces, e.g. fieldbus and Ethernet, is not
possible.
5.5.1
Ethernet TCP/IP (optional)
The Ethernet interface is galvanically isolated (testing voltage: 500 V). A standard patch cable
(e.g. CAT5E) can be used to connect the Ethernet interface. A special cable gland is available
for this purpose which allows users to guide pre-terminated cables through the housing. Via
the Ethernet interface, the device can be connected using a hub or a switch or directly to office
equipment.
• Standard: 10/100 Base T/TX (IEEE 802.3)
• Socket: RJ-45
• Max. cable length: 100 m
