The BL200 distributed I/O system consists of 3 parts: Coupler, I/O modules and terminal modules.
The system needs to use the power module to provide 24VDC system voltage and 24VDC field voltage. Since two independent power supplies are used, the field voltage input interface and system voltage input interface of BL200 series couplers are electrically isolated from each other.
When assembling fieldbus node modules, each I/O module can be arranged in any combination, and it is not required to be grouped by module type.
A terminal module must be plugged into the end of a fieldbus node to ensure correctdata transmission.
