Issued: 12/12 Supersedes: 4/12 Description The APP 700 hardware series are especially designed for waste and clean water systems, both in construction and functionality. The RTUs¹ are developed to meet the demands of powerful flexible monitoring and control units and are prepared to work with various types of communication e.g. SCADA system, radio, ethernet cellular systems, dedicated and dialed-up telephone lines. The RTUs complies with the required electromagnetic emission and immunity standards. The front panel is user-friendly with self-instructive symbols. The RTUs are easy to install and commission.

A special version is available for Simplified Chinese characters. Expandable system The possible number of inputs and outputs can be expanded to 600 when external RIO modules are connected. The RTU communicates with the RIO modules on a SIO field bus and an optional SIO driver is mounted in the RTU to run the SIO bus. ¹ Remote Terminal Unit
Communication The RTUs series is equipped with serial communication ports for local PC connection and modems. Accessories Standard software. Level sensor. Modem. Power supply. Over voltage protection. SIO driver. RIO modules. Overlays.
