Overview

The EZ-RTU is a general purpose single board RTU that is designed with an integrated spread spectrum radio, and a C programmable core processor module.

The base unit has eight digital inputs, eight digital outputs, and can be expanded to a total of 24 digital inputs, and 24 digital outputs directly from the base board.

As designed, the EZ-RTU functions as a low cost polling master to bring back multiple digital or analog I/0 data from up to 32 RTUs.

Other applications are for point-to-point RTUs which act as wire line replacements, with 24 D/I mapped to 2/4 DO as a starting I/O make-up.

Digital and analog expansion is accomplished by adding Automation & Electronics, Inc. Smart I/O modules. By adding these expansion modules, the I/O is expandable to 216 D/I, 216 D/O, 128 A/I, 128 A/O.

The EZ-RTU can also be used to pass MODBUS data serially to a PLC or HMI. In this mode, the unit also acts as a polling master. The I/O data is available to the PLC via standard MODBUS function calls.
