Model 2410 is a compact open-frame module that interfaces 48 general-purpose TTL/CMOS compatible digital input/output (DIO) signals to a 10/100 Mbps Ethernet. It features advanced signal processing functions that reduce the host computer’s burden in measurement and control applications.

The module communicates through its built-in web and telnet servers, using telnet for automation applications and an embedded web site for configuration, manual control, and diagnostics. Precompiled API libraries are provided for Linux and Windows, along with open source (C language) code to enable porting and customization.

The unit has a small footprint, requires only a single 24VDC power source, and can be quickly and easily mounted by snapping it onto a standard DIN mounting rail. It will interface directly to many standard solid state relay racks, and it has an auxiliary power output that is capable of supplying 5VDC power to solid state relay racks or other modest external loads.

DIO Functions

Each open-collector DIO channel can operate as an input, an output, or in wired-or mode. A number of special functions such as debounce, edge detection, and PWM output, are available on each channel. All channels are synchronized to a common 1KHz clock to guarantee true state machine behavior. An LED indicates each channel’s physical state.

Software debounce can be enabled for any input signal, with debounce interval ranging from 0 to 255 milliseconds. Also, edge detection and capture may be enabled for any input signal and, if desired, asynchronous notification messages (i.e., «interrupts») will be sent to an Ethernet client when edge events are captured.

Outputs are capable of 24mA active-low output drive, and internal pull-up resistors are provided for all channels. Each output channel may be independently configured to function in the conventional fashion (directly controlled by Ethernet clients) or as a PWM generator with one millisecond resolution.

Signal Connections

A standard 50 pin header is provided for connecting the module to external solid-state relay racks or custom OEM signal distribution systems.

Sensoray also offers an optional termination board, Model 2410TA, which can be top-mounted to the module to add convenient field wiring terminal blocks without enlarging the module’s footprint. The spring-loaded terminals allow quick connection of 24-16 gauge wires.

LabVIEW Demo

In addition to the standard API, Sensoray provides a LabVIEW application which demonstrates how to interact the 2410.
