Data Handler (DH)

  • Overview

    Data Anywhere, Anytime ...

    New concepts in system design require remote single point signals to be conditioned, converted, logged, communicated to other locations, operate/control field devices and interface with existing or new peripherals.

    The DATA HANDLER's built-in signal conditioning, low power requirements, hermetic seal, small package size, ease of installation and hardened micro-controller makes it perfect for these types of applications.

    The AGM DATA HANDLER truly allows data to be accessed anywhere, anytime.

  • Optical I/O isolation: The input signal from a field sensor is optically isolated from the other circuitry of the Data Handler. System startup problems resulting from inadvertent ground loop conditions are precluded. System operational shutdowns due to lightning and utility fault currents are greatly minimized.

    Minimal Power Requirement: The Data Handler is ideal for those remote locations where it is not practical or cost effective to bring service power to. Batteries or a small solar power system is all that is required for operation.

    Communications: Interfaces include direct, fixed/spread spectrum radios, leased/dial-up line modems and Ethernet.

    Eight-channel time division multiplex: The "MUX PUK" auxiliary device allows one Data Handler to monitor 8 analog or 64 digital inputs. Monitoring costs can be reduced to one twentieth of that using other monitoring devices.

    Stand-alone controller: The Data Handler can be programmed to perform any type of controller function including PID features.

    RTU Function: Flexible Data Handler software lets the Data Handler function as a RTU in all SCADA systems. You can interface with Windows-based PC programs like Genesis, Intellution, Wonderware, Lookout, etc. or AGM's own TakeCharge program. It can be adopted for use with any protocol including Modbus and its variations.

    Addressable: The Data Handler is addressable for Distributive Control Schemes. You can use 256 different addresses in a single system application.

    Event or time driven data-logging with programmable smoothing: You have 32K of nonvolatile RAM and a perpetual clock for data logging. Stored data files can be directly downloaded to popular programs like EXCEL, ACCESS, etc. You can not lose stored data with loss of communications in a Monitoring System.

    Signal Conditioning: Erratic and "noisy" signals from input sensors are easily "smoothed", without eliminating the important perturbations of the variable being measured.

    Internet, Email, and Pager Interfaces: The Data Handler's communications auto-dialer lets you transmit remote data and alarm conditions using the Internet, AOL, and CompuServe networks.

    Remote Diagnostics: The Data Handler software files include programs with "zero sum logic" and relay ladder logic schemes to identify wiring errors and equipment malfunctions during "startup" and operating conditions.
