analog and discrete I/O modules that support the
Modbus-RTU protocol for distributed I/O applications |
The DI-900MB Series I/O System is a collection of analog
and discrete I/O modules with Modbus-RTU protocol network
communication. These 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 DI-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, recorder, variable frequency drives, valves,
and other control equipment. Discrete I/O modules monitor
and/or control the on/off status of industrial devices.
All modules may be mixed/matched and coexist on the same
Modbus network in a manner that precisely addresses the
requirements of any given application.
