BASIC INFORMATION
-
It is recommended that the power supply negative pole be grounded.
-
It is possible to supply up to eight 350 ohm load cells or sixteen 700 ohm load cells.
-
For 4-wire load cells, make a jumper between EX- and REF- and between EX+ and REF+.
-
Connect terminal “– SUPPLY” to the RS485 common of the connected instruments in the event
that these receive alternating current input or that they have an optically isolated RS485.
-
In case of an RS485 network with several devices it is recommended to activate the 120 ohm
termination resistance on the two devices located at the ends of the network, as described in the
paragraph RS485 SERIAL CONNECTION.
-
Option E/EC : selects 12 groups of 5 setpoint.
