ABB SC520 3BSE003816R1 Submodule Carrier

Power supply voltage: 24VDC (common type)

Input Current: (Redundant power supply supported) 0.5A max.

Output voltage: 5V DC (Power supply for submodules)

Output current: Max. 10A (which can be connected in parallel with multiple modules).

Words, in fact, are only a few bytes long and the smallest parameter of the structure is also a few bytes.

32MB Flash + 64MB RAM Memory (real time data support).

Ethernet ports: 2 (10/100Mbps) RS485 serial port: 1

Supported Protocol: Modbus RTU/TCP, PROFIBUS DP, Ethernet/IP

ABB SC520 also provides hot-swappable support, which means that when a sub-module malfunction, this can be easily replaced while the other sub-modules keep running without stopping the CPU.

Support for various module types: ABB SC520 supports ABB and third-party I/O and communication modules, enabling flexible function configuration as required.

Industrial-grade durability

Versatile Temperature Tolerance: Operating temperature -25°C~+70°C (Enhanced model supports -40°C), adapts in a high temperature, polar and other harsh environments.

IP20 dustproof, corrosion resistant ISA-S71. 04 G2) that is used in chemical, metallurgical etc. scenarios.

24V DC power supply redundancy: Two sets of 48V DC input, with built-in over-voltage/over-current protection to ensure that the computer works continuously.

High speed: ABB SC520 has 32-bit processor for real data acquisition and multi-tasking.

Smart diagnosis: Real-time monitoring of module status through LEDs and logs by ABB SC520, Automatic site fault prompt。

Cream of the crop interfaces: ABB SC520 comes with Ethernet, RS485 by default and supports Profibus, Modbus, Ethernet/IP and other protocols.

Data connection: Support data interaction with third-party platforms, integrated with ABB control system (AC 800M, etc.).

Third, and perhaps most importantly, you are structured to comply with safety regulations.

Explosion-proof certification: ATEX, IECEx, etc. certified explosive gas/dust environment (Zone 1/21).

Compact installation: Mounting on DIN rail / wall mounting, compact size, to save space in control cabinet.

ABB SC520 is one of the DCS system widely used in petrochemical, metallurgy, food and beverage industries and provides redundant control of DCS systems.

Grids: Distributed data acquisition for photovoltaic plants and smart grids.

Transportation and logistics: local control units rail transit signalling systems
