Wiring with configuration examples
Explanation of the abbreviations:
A
= analog
BH
= binary high side
BL
= binary low side
CAN
H
= CAN interface
CAN
L
= CAN interface
CYL = inputs for time period measurement
FRQ = frequency inputs
PWM = pulse-width-modulated signals
RxD = serial interface (data received)
TxD = serial interface (data transmitted)
VBB
O
= supply voltage outputs
VBB
S
= supply voltage sensors/module
%IWx
= IEC address for analog input
%IX0.xx = IEC address for binary input
%QX0.xx = IEC address for binary output
digital
e.g. two-way valves
PWM, current-controlled
e.g. proportional valve
PWM
e.g. Danfoss proportional valve
(pull-down resistor integrated)
For safety reasons the valve is
supplied with voltage via a
binary output.
