18.1.- INTRODUCTION and FUNCTIONAL DESCRIPTION
The A1P4RCAN CAN expansion module provides to the TM70 receiver, 4 relays output and an analogue output
at the same time. The analogue output simulates a digital potentiometer with 64 steps available in each semiaxis
of the power supply. See the diagram block below (size ½ of LR72):
CAN
This CAN expansion provides to the user the following outputs :
An analogue output simulated by a digital potentiometer with 128 steps and galvanically isolated.
Free to use four relays outputs, K1, K2,K3 and K4.
These outputs are controlled by CAN BUS, writing in its addresses CANOpen frames. The CAN address of the
electronic card is conformed using the 7 jumpers of P1 connector. Jumper in position 1 corresponds with the
first bit of the CAN address. Thus, inserting several bridges it is possible to select different addresses from «1 »
until «127» (2 7 ), maximum.
Very important : The address « 0 » is not a valid address ; so the board allways must be fitted with at least one
jumper. With one jumper it is possible to configure 7 different addresses.
18.2.- CONNECTIONS & JUMPERS CONFIGURATION
LR72 ELECTRICAL CONNECTION
This expansion is connected to the LR72 board using two connectors; 2 pins connector labeled RL4 for power
supply 8-30V (+VI and GND); 5 pins connector labeled RL3 for CAN Bus connection with the following signals :
Pin Name Function
1 GNDCAN Ground
2 CANL CANL bus signal (CANLow signal)
3 SHLCAN Shielding
4 CANH CANH bus signal (CANHigh signal)
