Electrical connections
Unscrew four lid screws and detach the lid from the device. Use the 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 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.
