SMART display module

The SMART Display Module is a CAN module for displaying CAN J1939 parameters on analog instruments. It reliably converts selected CAN bus values into analog 4 to 20 mA signals, enabling easy connection of display instruments, a PLC, or a higher-level CAN control system.
The module has four configurable sensor outputs with 4 to 20 mA. These outputs can be used to output current engine and operating data from the CAN bus and process it further in the CAN control system or other systems. The use of an Rshunt with 0 to 100 ohms is supported.
Typical areas of application are mobile and industrial applications in which existing analog displays are to be reused or CAN data is to be efficiently integrated into higher-level control systems.

Functions and features

Display of CAN J1939 parameters on analog displays
Output of CAN bus values as 4 to 20 mA current signals
Four analog outputs for sensor value transmission
Suitable for connection to PLC systems
Reliable conversion of CAN signals without direct intervention in the sensor technology

Assignment of analog outputs

PIN A supplies 4 to 20 mA for oil pressure 0 to 10 bar SPN 100
PIN B supplies 4 to 20 mA for coolant temperature 0 to 120 degrees Celsius SPN 110
PIN C supplies 4 to 20 mA for fuel rate 0 to 700 l SPN 183
PIN D supplies 4 to 20 mA for actual speed RPM 0 to 5000 SPN 190

Electrical connection

Pin 15 → +UB on pin 8
Pin 31 → GND on pin 4
