MODBUS RTU IO

Acromag's BusWorks™ 900 Series I/O System is a collection of analog and discrete remote I/O modules with Modbus-RTU protocol network communication. BusWorks™ modules are ideal for a wide variety of distributed I/O applications including data acquisition & control, process monitoring, and test & measurement. Windows®-based configuration software simplifies module setup with easy selection of input/output ranges, alarm setpoints, and other operating parameters.

All 900MB I/O modules communicate over a high-speed RS-485 network supporting data transfer rates up to 115K baud. Analog input modules accept variable DC voltage, current, and thermocouple sensor signals and feature local limit alarm capabilities. Analog output modules provide DC voltage or current field control signals for local displays, recorders, variable frequency drives, valves, and other control equipment. Discrete I/O modules monitor and/or control the on/off status of industrial devices.
