Modbus I/O Modules

Modbus is one of the industrial field bus protocols. ModBus network has only one host. All communications issued by the host, this protocol supports traditional RS-232, RS-422, RS-485 and Ethernet devices. There are two kinds of transmission modes to choose from the ModBus system, a model to ASCII, another mode is RTU, the network can support as many as 247 remote slave controllers, but the actual number of slaves depend on the used communication equipment.

Module series Modbus-RTU remote I / O can be connected into a network with programmable logic controllers, RTU, SCADA systems, third-party devices defined by DCS Modbus protocol, to build a variety of complex monitoring systems, and to facilitate maintenance and extension of the system.
