2.4.3Removing the ROC827 from the DIN Rail

To remove the ROC827 from DIN rails, gently lever the DIN rail catches (located on the top of the housing) up approximately 3-4mm (1/8”). Then tilt the top of the ROC827 away from the DIN rail.

2.5ROC800-Series Expanded Backplane (EXP)

The expanded backplane has connectors for the central processing unit (CPU), the power input module, and all the I/O and communication modules. Once a module is completely inserted into the module slot, the connector on the module fits into one of the connectors on the backplane. The backplane does not require any wiring, so no jumpers are associated with the backplane.
