The BC8150 Compact Bus Terminal Controller with serial RS232 interface extends the Beckhoff small controller series by a cost-optimized version in a compact housing. An open serial protocol – like in the BK8x00 Bus Couplers – and the Modbus RTU/ASCII protocol are implemented. The address and the protocol are selected via the two rotary selection switches.
The BK8100 Bus Coupler usess the physics of the RS232C (V.24) specification for data transmission. Application of the Bus Coupler with a serial interface is suited to those cases in which the use of a fieldbus system can be omitted.
The KL1232 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit.
The KL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitized with a 16 bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system.
