Product Features
ABB GRBTU-01 supports mainstream industrial protocols such as Modbus TCP, Profibus DP, and EtherCAT, enabling direct connection to ABB PLC/DCS systems and third-party devices for cross-brand system integration.
ABB GRBTU-01 features a built-in protocol conversion engine that automatically adapts to different communication formats, reducing system integration complexity.
ABB GRBTU-01 supports analog input/output and digital input/output with a resolution of 16 bits, ensuring signal conversion error ≤ ±0.1%.
ABB GRBTU-01 features channel-to-channel isolation voltage of 50V and system-to-ground isolation of 500V AC, effectively resisting electromagnetic interference (EMC).
ABB GRBTU-01 continuously monitors power voltage and communication link status, sending fault alarms via LED indicator lights and the backplane bus.
ABB GRBTU-01 supports cable break detection and hot-swap functionality, allowing modules to be replaced while the system is running, thereby minimizing downtime.
Product Using Principle
ABB GRBTU-01 can receive digital commands from the controller and convert them into a signal format recognizable by field devices through its built-in protocol stack.
ABB GRBTU-01 can connect to sensors or actuators via analog/digital interfaces to enable bidirectional data transmission.
ABB GRBTU-01 supports dual-link communication (e.g., primary + backup Profibus DP), automatically switching to the redundant path when the primary link fails to ensure uninterrupted data transmission.
ABB GRBTU-01 can real-time transmit device status back to the control system, forming a closed-loop control loop.
