Electrical connections
Unscrew four lid screws and detach the lid from the device. Use M16 cable gland to let in
cables of the power supply and of the external devices. Attach the power cable to the
device without turning it on. Using the connection diagram below, connect the analog
outputs and digital interface terminals to the relevant devices according to your tasks.
PCB without PSU and relays
The screwless quick connect spring terminals on the E2618 series devices are suitable for
a wide range of wires with 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 twisted pair cable, e.g. LiYY TP 2×2×0.5 mm
2
or CAT 5, to connect the device to 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.
