LC3100 | PROFIBUS “Low Cost” Bus Coupler
The LC3100 “Low Cost” Bus Coupler is marked by a smaller design and a more economical connection method. Its functions correspond to those of the PROFIBUS BK3110 Bus Coupler in relation to operation with Bus Terminals and to the fieldbus properties. Up to 64 digital input/output terminals can be connected. The firmware can be updated via the configuration interface.
The LC3100 Bus Coupler is particularly suitable for use in small, low-price stations. The 24 V DC supply voltage feeds the peripheral devices via the power contacts. It also feeds the Bus Coupler and K-bus electronics. Electrical isolation from the I/O level is omitted from the Bus Coupler, but can if necessary be implemented by means of a power feed terminal.
The LC3100 Bus Coupler can be replaced by a Bus Coupler from the BK3110 series.
