GND
common analog inputs and free of voltage digital inputs
AI1
analog input 1 (which can be set via configuration parameter for NTC/Pt 1000 probes and for
0-20 mA/4-20 mA/0-5 V ratiometric transducers)
AI2
analog input 2 (which can be set via configuration parameter for NTC/Pt 1000 probes and for
0-20 mA/4-20 mA/0-5 V ratiometric transducers)
GND
common analog inputs and free of voltage digital inputs
AI3
analog input 3 (which can be set via configuration parameter for NTC/Pt 1000 probes)
AI4
analog input 4 (which can be set via configuration parameter for 0-20 mA/4-20 mA/0-5 V
ratiometric/0-10 V transducers)
CAN port (not available in model EPD4BX3)
Non optoisolated CAN port, with CANBUS communication protocol.
Terminal
Meaning
CAN+ signal
+
CAN- signal
-
GND ground
-
the maximum number of devices that can make a CAN network (32) depends on the bus load; the bus
load depends on the baud rate of the CANBUS communication and on the kind of device in the network
(for example: a CAN network can be made of a programmable controller, of four I / O expansions and of
four user interfaces with baud rate 500,000 baud)
-
connect the CAN port using a twisted pair
-
do not connect more than four I / O expansions.
For the settings about the CAN port look at chapter 7 “CONFIGURATION”.

Meaning
GND ground
VDC
power supply remote user interface (22... 35 VDC, 100 mA max.)
