An ABB ac31 system always contains at least one ac31 basic unit. There are three basic units:
40 series basic unit with local interface for input / output expansion
50 series basic unit, local interface is used for input / output expansion, and cs31 system bus interface is used for decentralized expansion
90 series basic unit with cs31 system bus interface for decentralized expansion
Each basic unit contains a specific number of digital inputs / outputs, in the case of occasional analog inputs / outputs in series 90. According to different basic units, the number of input / output can be increased, and the input / output expansion directly connected to the basic unit or remote input / output unit through cs31 twisted pair can be increased.
Basic unit with cs31 system bus
In the 50 and 90 series, the number of inputs / outputs of the basic units can be increased by adding remote units. The basic unit of the control system is called the main control basic unit. The bus length without amplifier is 500m, and the bus length with 3 amplifiers is 2000m (one NCB or ncbr unit can amplify the bus by 500m).
A master basic unit can manage up to 31 connection points, such as:
Series 50 remote units with expansion possibilities: a plurality of 6 expansion units, including, for example, a plurality of 8 analog input channels and 8 analog output channels
Series 30 and 90 remote units (no possibility of expansion) with analog or digital input / output
ABB NCSA 01 variable speed drive interface is adopted
