IBS RBC SWITCH INTERBUS Data Sheet Remote Bus Switch Data Sheet Revision A 02/1997 Product Description The remote bus switch IBS RBC SWITCH permits to connect a remote bus topology for reasons of device availability with a second, redundant PLC. Features - D-SUB 9 remote bus connectors for two incoming remote buses and one outgoing remote bus - 24 V nominal input voltage - Pick-up time max. 4 ms - DIN-rail mounting Application - Operation of a bus topology with two controller boards that can be used alternatively Figure 1: IBS RBC SWITCH 5088A Phoenix Contact GmbH & Co.

The length of the remote bus cable must not exceed 400 m for every remote bus segment. The remote bus switch does not start a new remote bus segment. The switching relays are supplied with a positive coil voltage via terminal A1 and with a negative coil voltage via terminal A2 (see Figure 3). When the coil voltage is applied the remote bus switch switches to the first input (IN 1). In the normal state the remote bus input IN 2 is connected with the remote bus output (OUT). The connector pin assignments on the input and output side are identical, which means that pin 1 on the input side is connected to pin 1 on the output side etc. (see Table 1). In order to reduce the installation times of an INTERBUS system as much as possible, Phoenix Contact offers pre-assembled bus cables (see Phoenix Contact Catalog Part 11: INTERBUS). Please refer to the INTERBUS Installation Manual IBS SYS INST UM E (Order No.27 54 80 4) for detailed information on all INTERBUS cable types. 5088A Phoenix Contact GmbH & Co.
