I/O Modules
for Modbus-RTU
Acromag’s BusWorks 900MB series is
a collection of analog and discrete I/O
modules with Modbus-RTU network
communication. BusWorks modules are
ideal for a wide variety of distributed I/O
applications including data acquisition,
control, process monitoring, and test &
measurement.
Analog input modules accept DC current,
voltage, or temperature sensor signals
and feature local limit alarm capabilities.
Analog output modules provide DC
current or voltage signals for local
displays, recorders, variable frequency
drives, valves, and other equipment.
Discrete I/O modules monitor and/or
control on/off status of industrial devices.
Windows
®
configuration software simpli-
fies module setup with easy selection of
input/output ranges, alarm setpoints, and
other operating parameters.
All 900MB Modbus I/O modules com-
municate over a high-speed RS-485 net-
work supporting data transfer rates up to
115K baud.
