SNAP DNP3 I/O

Opto 22 SNAP-DNP-ASDS brainSNAP DNP I/O from Opto 22 is a DNP slave hardware device for use with DNP3-based SCADA systems. A low-cost alternative to remote telemetry units (RTUs), SNAP DNP I/O systems provide a non-proprietary, standards-based way to bring critical utility assets under the scope of a DNP3 SCADA network.

SNAP DNP I/O-based systems use a broad array of optically isolated analog and digital SNAP I/O modules to connect to power transformers, motor operators, circuit breakers, and other critical utility systems, linking this equipment to master SCADA stations over standard Ethernet networks via the DNP3 protocol.

SNAP DNP I/O systems offer reduced software costs, easy system expansion, and operational savings for applications such as:

  • Monitoring, control, and data acquisition from remote electrical and other utility equipment
  • Interoperability between multi-vendor devices
  • Integrating legacy equipment into a DNP system.

Opto 22's first SNAP DNP I/O product is the SNAP-DNP-ASDS, a compact I/O and communications processor (or "brain") that mounts on standard Opto 22 SNAP mounting racks and interfaces with Opto 22 analog and digital SNAP I/O modules. This brain uses an embedded Linux operating system, and includes ports for RS-232 serial and 10 Mbps Ethernet links.
