Wiring
The IRU series sensors are configured with either a terminal wiring strip (IRU-
2002 & IRU-2003 only), a multiconductor cable or a micro-connector. For
optimal performance, the sensors should be supplied 24 Vdc. A high quality
power supply is recommended.
NOTE: Clock synchronization (available on many models): is used to help
prevent cross-talk between sensors located in close proximity. When the clock
synchronization lines of two or more sensors are connected, the sensors will
synchronize the transmit signals of each sensor. The sensors must share a
common ground in order for the clock synchronization feature to function.
Isolated 4-20 mA Output
(IRU-2003 only)
*Digital Output (IRU-2002 and IRU-2003 only) is used to interface with APG
digital displays--part no. ACC-1007 or ACC-1008.
