Decoupling power supply to CIB – the C-BS-0001M decoupling module

The C-BS-0001 decoupling module provides proper power supply of one CIB. The module decouples the bus power supply source from peripheral modules and the bus master, in order to secure powering of the bus and at the same time separating the communication from the power source. The module is implemented in 1M housing on a DIN rail; green LED on the front panel indicates correct voltage at the module output. The output is protected by a resettable electronic fuse against a short circuit on the CIB. This module is designed to boost the CIB power circuitry of the basic modules fitted with a CIB power supply circuit only with a limited output (e.g. CP-1004, CP-1006), or for older versions of the Foxtrot basic modules, which had no CIB supply circuits installed.

Maximum load of CIB supplied from this module is 1 A.

For this load it is necessary to rate both the C-BS-0001 power supply source and the total consumption of all connected and powered CFox peripheral modules.

Notes:

1. The power supply must be stabilized 24 VDC, complying with SELV requirements.

2. CIB is powered by a maximum current of 1 A (the sum of all connected CFox peripheral modules).
