Snap Ethernet I/O Connectivity

Opto22 Snap Ethernet I/O features a wide variety of analog and digital I/O modules that reliably interface the ORION® motion controller to industrial devices such as switches, sensors, solenoids, valves and motor starters.

Snap Ethernet I/O combines a rack and controller for each node. The user can select appropriate modules (AC In/Out, DC In/Out, sinking/sourcing, Analog current/voltage, etc.) for their specific application

The Snap I/O brain modules are compact, flexible, high-performance processors that provide the interface between the I/O modules mounted to the rack and a dedicated Ethernet network. Industrial racks provide an efficient method for mounting that minimizes panel space.

Pluggable I/O modules are color coded by function and provide a high degree of isolation and noise immunity between the motion controller and external components.

The AC output modules utilize zero voltage turn-on and zero current turn-off of the load to greatly reduce generated EMI and RFI. They also feature an internal dv/dt snubber network for protection from voltage transients on the line.

All discrete I/O modules feature internal LED indicators. Digital output modules below (except for the ODC5R) include replaceable fuses.

Snap Ethernet I/O -- At A Glance

• Standard Connectivity Solution -- Snap Ethernet I/O provides a standard connectivity solution for interfacing digital and analog I/O to the ORION motion controllers that is easy to implement, operate and maintain. High speed digital and analog signals can interface to the ORION controller using an industry standard Ethernet network that’s dedicated for I/O control.
• Flexible Ethernet Interface -- All Snap I/O racks connect to ORION using a Brain module, one per rack. The Brain module interfaces to the Ethernet network providing a high speed connection to all I/O in the rack. I/O can be remotely distributed throughout the machine.
• Digital I/O Modules -- Snap Ethernet I/O provides a full line of digital I/O modules. DC inputs (2.5 to 32 VDC), DC outputs (5 to 60 VDC), AC inputs (90 to 280 VAC) and AC outputs (12 to 280 VAC) provide flexible interface options. All digital modules feature a compact 4 channel design. Each module incorporates a pluggable interface connector for easy wiring.
• Analog I/O Modules -- Analog voltage inputs range from -10 to +10 volts. Analog output modules provide 0 to 10 volts, +/- 10 volts, and 4-20 mA ranges. Analog input modules are available as efficient 2-channel and 4-channel devices. Interface to temperature sensors, load cells, dancer control systems, and other industrial analog voltage or current control points.
• Minimum Panel Space -- Full range of racks will accept either digital and analog I/O modules. From 4 position to 16 position racks with one 16 position provided for only digital modules allow the OEM designer to use a minimum amount of panel space. DIN-Rail mounting adapters are available.
• I/O Functionality -- Basic I/O operations are supported for virtually all Opto Snap I/O modules including the products listed below. See our Ethernet I/O Application Note for more details.
