Modbus RTU I/O Modules

I/O Modules with Modbus RTU Communication

Acromag's BusWorks 900MB Series is a high-performance collection of analog and discrete I/O modules with Modbus-RTU network communication. These units feature universal input/output ranges and an intelligent microcontroller to provide extreme flexibility and powerful monitoring and control capabilities. BusWorks modules are ideal for a wide variety of distributed I/O applications including data acquisition, control, process monitoring, and test & measurement.

To ensure unsurpassed performance, these I/O modules employ the latest digital technology. State-of-the-art flash microcontrollers plus optically isolated input, output, power, and network circuits increase noise/transient immunity and prevent ground loops. Status LEDs provide diagnostic feedback and visually indicate which channels are outside their calibrated range.

Sophisticated watchdog timer functions allow the application to define the module's failsafe output state. The watchdog timer invokes the failsafe condition when communication between the host and module exceed a duration specified by the application. For further security, a second hardware watchdog timer monitors the microcontroller for failed operations or a "lock-up" condition and automaticaly resets the unit.
