System Assembly
The Micro800 expansion I/O module is attached to the controller or another I/O module by
means of interconnecting latches and hooks, as well as the bus connector. The Micro850
controller and expansion I/O modules must terminate with a 2085-ECR Bus
Terminator module.
Be sure to lock the module interconnect latches and tighten the RTB hold down screws before
applying power to the module.
For installation of the 2085-ECR module, refer to Micro800 Bus Terminator Module
Installation Instructions, publication
2085-IN002 .
Field Wiring Connections
In solid-state control systems, grounding and wire routing helps limit the effects of noise due to
electromagnetic interference (EMI).
Wire the Modules
Included with your module is a single 12-pin Removable Terminal Block (RTB). Basic wiring of
the module is shown below.
ATTENTION: Failure to connect a bus terminator module to the last expansion I/O module will
result in a controller hard fault.
ATTENTION: Do not wire more than 2 conductors on any single terminal.
