The screwless quick connect spring terminals on the E2608 series devices are suitable for
a wide range of wires with a cross-section of 0.2...1.5 mm
2
. We recommend to strip the
wire end by 8...9 mm and use wire end sleeves.
To connect the wire, insert the wire end into the terminal hole. To disconnect, push the
spring-loaded terminal lever, pull the wire out, and release the lever.
Use a twisted-pair cable, e.g. LiYY TP 2×2×0.5 mm
2
or CAT 5, to connect the device to the
RS485 network. A and B on the device represent DATA+ and DATA- respectively, polarity
must be respected when connecting to an external RS485 network.
Both analog outputs can be independently changed between 4-20 mA and 0-10 V type
using jumpers J1 (OUT1) and J2 (OUT2). By closing pins on a specific jumper the related
output is 0-10 V, with an open jumper the output is 4-20 mA. Power restart is required after
changing the position of the jumpers.
NOTE!
The outputs are not galvanically isolated from the external power supply and share
a common 0V. Allowed load resistance limits are stated in the Specifications table. To
power the instrument from an external power source, connect terminals 0V and +U to the
source. If the integrated mains power supply module is used, connect terminals L and N to
the mains.
NOTE!
Actuator short-circuits should be avoided, to protect the instrument relays using
external fuses or safety switches.
