Mounting Dimensions and DIN Rail Mounting

DIN Rail Mounting

The module can be mounted using the following DIN rails: 35 x 7.5 mm x 1 mm (EN 50 022 - 35 x 7.5)

For environments with greater vibration and shock concerns, use the panel mounting method, instead of DIN rail mounting.

ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately.

Before mounting the module on a DIN rail, use a flat-blade screwdriver in the DIN rail latch and pry it downwards until it is in the unlatched position.

1. Hook the top of the DIN rail mounting area of the module onto the DIN rail, and then press the bottom until the module snaps onto the DIN rail.

2. Push the DIN rail latch back into the latched position. Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or 1492-EAHJ35) for vibration or shock environments.

To remove your module from the DIN rail, pry the DIN rail latch downwards until it is in the unlatched position.

Panel Mounting

The preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance: ±0.4 mm (0.016 in.). For mounting dimensions, refer to Micro830 and Micro850 Programmable Controller User Manual, publication 2080-UM002

Follow these steps to install your module using mounting screws.

1. Place the module next to the controller against the panel where you are mounting it. Make sure the controller and module are spaced properly.

2. Mark drilling holes through the mounting screw holes and mounting feet then remove the module.

3. Drill the holes at the markings, then replace the module and mount it. Leave the protective debris strip in place until you are finished wiring the module and any other devices.

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

ATTENTION: Failure to connect a bus terminator module to the last expansion I/O module will result in a controller hard fault.

Field Wiring Connections

In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI).

ATTENTION: Do not wire more than 2 conductors on any single terminal.
