Table I. Electrical terminal connections for
CF8-W-Disp-AL
Note 1: The ground terminal is used as negative power supply DC input or AC phase ground
(halfwave rectifier). The signal ground M, protected by a PTC resistor, is the same as power ground
G0 (permitting a ”3-wire” configuration). A single transformer may be used for the entire system.
Note 2: CF8-W-Disp-AL can deliver a voltage or a current loop for Out(1)/Out(2). To change between
voltage and current output mode the hardware jumpers are used. There is one jumper for Out(1) and
one for Out(2), so that one output can be a voltage output and the other a current output. Both, voltage
output and current output, can have start points 0 % (0-10 VDC or 0-20mA) or 20% (2-10 VDC or 4-
20mA). The same start point is used for both outputs. See the user manual.
