Guidelines for Station Planning
D301087 1211 - BL20 CANopen 6-10
C-rails can be used for a common voltage supply when relay modules are planned. To accomplish this,
the load voltage is connected to a Power Feeding module with the BL20-P4x-SBBC base module with
tension clamp or screw connection. All the following relay modules are then supplied with power via
the C-rail.
Cross-connecting relay module roots is achieved by the use of jumpers. The corresponding wiring
diagram including the jumpers can be found in chapter 4.
6.2.6 Direct Wiring of Relay Modules
As well as the options mentioned above, relay modules can be wired directly. In this case, base modules
without C-rail connections should be chosen to guarantee the potential isolation to the adjoining
modules.

Attention
When relay modules are planned and the C-rail is used for a common voltage supply, a further
power distribution module must be used for the potential isolation to the following modules.
The C-rail can only again be used as a PE following potential isolation.
