17.1- INTRODUCTION and FUNCTIONAL DESCRIPTION
The INCAN interface allows to increase (until N*5 +1) the capacity of analogue and digital inputs in the LR72
electronic card. ( N = number of INCAN cards; maximum = 2 units).

10-20V
Each INCAN interface can support 5 (maximum) digital/analogue input micro-modules.
IN4D: 4 digital inputs module (0 - 24VDC).
IN010V: Voltage analogue input (range: 0 - 10 VDC).
IN0450P: Pulses input (range: 0 – 450pps; pulses per second). (Example: To use with anemometer
sensors).
A TM70 system can operate with 2 INCAN electronic cards (maximum capacity), so the following
configurations will be supported:
40+ (4) IN4D card directly connected to the LR72 max. 44 digital inputs (0-24VDC).
10+ (1) IN10V card directly connected to the LR72 max. 11 analogue inputs (8 bit resolution).
10+ (1) IN450P card directly connected to the LR72 max. 11 input pulsed signal counter (0-450
pps).
17.2– CONNECTIONS & CONFIGURATION JUMPERS
INCAN
POWER SUPPLY
The INCAN expansion is connected to LR72 electronic card through two connectors: RL4 (2 pins -> +VI and
GND signals) and RL3 (5 pins) for CAN bus signals. in practice GNDCAN and SHLCAN are connected.
