Modbus RTU Analog I/O
Multi-channel units with flexible I/O ranges provide an isolated network interface for voltage, current, and temperature sensor signals or for non-networked controller signals. High-resolution, low noise, A/D converters deliver high accuracy and reliability.
Analog Input Highlights
♦ Universal I/O ranges support a variety of devices
♦ Differential inputs eliminate ground loops
♦ Discrete outputs enable local limit alarms or host-controlled on/off switching
♦ Modbus-RTU high-speed RS-485 communication
Control up to 4 devices with a single unit with 900MB output modules. These units provide an isolated network interface for analog output signals, Outputs can be used to cotnrol mechanical equipment or write to display devices, data loggers and recorders, or to transmit data to non-networked PLCs and controllers.

♦ Modbus-RTU high-speed RS-485 communication
Modbus devices communicate using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query. A slave is any peripheral device (I/O transducer, valve, network drive, or other measuring device) which processes information and sends its output to the master using Modbus. Acromag Series 900MB I/O Modules are slave devices, while a typical master device is a host computer running appropriate application software.
