Designed using the latest Digital Signal Processing (DSP) technology, the DL 3000 will meet your data acquisition, processing, control and communication requirements.
The analog input channels can be differential or single ended and offer voltage protection to provide reliable monitoring in noisy environments. Supported measurement and sensor types include temperature, 0-5 Vdc, current, 4-20mA loops, resistance, bridges, strain gauges, thermocouples, quadrature, pulse and frequency - all returned in engineering units of your choice. The DL 3000 provides a 24 Vdc loop power supply with suffi cient current to drive sensors. Switchable
excitation and triggering are provided on all channels to simplify wiring and installation.
The DL 3000 provides several popular data bus I/O’s including; SDI-12 (Version 1.3), Two (2) RS-232 ports, RS-485 (optional), and USB 2.0. Other features include a Secure Digital SD card interface that can store over two gigabytes of sampled data.
The DL3000 is designed to be the hub for future expansion hardware including; a graphics LCD display, enhanced digital and analog outputs for user control of sensors and actuators, Bluetooth, ZigBee, Wi-Max, GSM/GPRS, and CDMA wireless communications, Internet connectivity, unlimited data processing and management through richly evolving Web Services and an optional camera attachment with video and image surveillance options, allowing photographs or video of an event to be taken and stored as it happens.
User specifi ed operations and mathematical functions and equations can be programmed into the DL 3000 using a Visual Basic-like programming language. Connecting the DL 3000 to telemetry modems, GPS, scales, PLC’s, and other
intelligent devices is made simple with a separate serial port on the back panel offering high-speed communications. The DL 3000 is Internet enabled through a 10/100 Base-T Ethernet connection (TCP/IP) and optional Wi-Fi.

The Stevens DataLogic 3000 is compatible with a wide range of equipment, including accessories to expand its performance.
|User interface is facilitated by PC / PDA application programs, a computer’s non-proprietary terminal program, and/or optional touch screen display. Stevens’ GUI interface programs for the DL 3000 support multiple languages such as English, Spanish and Chinese.|
|Multiple expansion modules can be added onto the DL 3000 for additional I/O requirements. Each expansion module supports eight (8) analog inputs, one (1) isolated 22 bit A to D input, one (1) analog output, one (1) pulse, one (1) quadrature pair, SDI-12 I/O channels, and one (1) power control output.||
