The S800 I/O is modular in design as a distributed process I/0 station, making it economical, flexible and easy to install, wire, and connect directly to the drivetrain. The modules and terminals can be combined to suit different space and application requirements.
Characteristic point
◆ Each module and channel status display light can be communicated via Porfibus DP or AF100 fieldbus for easy error diagnosis
Rich I/O module types
Standard DIN rail mounting
Support power and bus media redundancy, can be switched without disturbance all outputs can be forced or pre-set
Easy connection of the drive system, reduced communication delay and cost savings All modules injection molded with IP20(IEC529) protection
The I/O module is locked with the terminal by mechanical locking keys
All modules can be plugged and unplugged with power
External intrinsic safety isolators can be connected
Function description
The S800I/ ○ can communicate with the higher level control system via the Profibus DP or ABB AF100 field bus.
The module status is displayed by the status display light and can also be obtained via the fieldbus. Data is periodically transmitted through the fieldbus, and the communication module periodically scans the IO module, and the scanning period is set to 4-108ms according to the module type.
S800 1/0 station
Each S800 I/O station consists of the following modules
·1 or 2 field communication modules
Up to 24 IO modules, can be divided into
-1 basic group
-7 extension groups with a maximum of 12 I/0 modules per group
