ABB Advant Controller 250 Modular Controller

2. Power Supply Unit

The system adopts an external 24V DC power supply and generates an internal working power supply isolated from the control bus by an internal power supply unit.

200-PSMG (Main Power Supply Unit): In addition to providing power, it is also responsible for generating the controller bus clock frequency, which (4, 6, 8, 12 MHz) will be automatically set according to the actual system configuration scale.

200-PSSG (from power unit): Used in large system configurations to expand power capacity and work in conjunction with 200-PSMG.

3. Communication Interface Units

This is the "bridge" connecting the system with the outside world, with a wide variety of types:

200-CI232: Dual channel non isolated RS232 interface with overvoltage protection.

200-CI485G: Dual channel optically isolated RS485 interface, supports half duplex/full duplex, requires external 24V power supply.

200-CIE: Single channel IEEE 802.3 (10M Ethernet) interface, supports MMS and SattBus over TCP/IP protocols, requires external 24V power supply.

200-CSIB: Dual channel isolated SattBus main pipeline interface.

200-ICN: ControlNet network interface, used for remote I/O connection, supports up to 15 adapters and 120 I/O units.

200-CIPB/DP: PROFIBUS-DP master station (Class 1) interface, used for remote I/O connection, can manage up to 512 I/O units, supports up to 99 adapters.

4. Backboard and auxiliary components

200-BPN backplane: Each backplane provides 2 slots, and up to 8 backplanes (i.e. 16 slots) can be used. Installed on DIN rails and equipped with mechanical coding keys to prevent module misplacement.

200-BPP screw terminal block: a 12 pole terminal block used to connect power and signal lines, directly plugged above or below the backplane, greatly simplifying wiring.

200-DU empty unit: used to fill the empty slots on the backplane, protecting the controller bus from mechanical and electrical damage.

200-BPT bus terminator: includes start and end plugs for correctly terminating the controller bus.

I/O system support: central and remote architecture

The Advant Controller 250 has extremely flexible I/O processing capabilities and supports mixed use.

Central I/O: Installed in the same cabinet as the controller, connected through a serial I/O bus. Supports up to 48 S200/S200L I/O units, distributed across up to 6 200-ANN adapters.

Remote I/O (via fieldbus):

Through ControlNet: using the 200-ICN interface. The maximum distance of coaxial cable is 500-1000 meters (up to 3-6 kilometers with repeaters), and fiber optic links can reach 7 kilometers under specific conditions. Supports up to 120 I/O units.

Through PROFIBUS-DP: using the 200-CIPB/DP interface. The communication distance varies from 100 meters to 1200 meters depending on the wave rate. Its expansion capability is extremely powerful, capable of managing up to 512 I/O units and connecting up to 99 200-APB12 adapters or 79 CI830 adapters (CI830 itself can also expand more I/O rows through fiber optic).

Supported remote I/O types: including S200, S200L, and the more powerful S800 I/O series.
