I/O : A-Series

 
A Series I/O Module

A-Series I/O and Communication Modules

SoftPLC offers a low cost, distributed I/O product line, which we call the "A Series". Modules are available for ethernet and serial networks. Also available in this product line are unmanaged ethernet switches and media converters.

All A-Series products are compact, DIN rail mountable, and can be mounted side-by-side or stacked piggy-back atop each other for small physical space applications.

The A-Series modules provide cost-effective protection and conditioning for a wide range of industrial control signals and systems. These modules are ideal when you have only a few I/O points, or need to distribute a small number of I/O points in several locations and you don't want to incur the overhead/cabling cost of a fieldbus network (eg: Profibus or DeviceNet).

A-Series Mounting Options

Applications include HVAC controls, sorting conveyors, utilities, and remote installations. One example is a weather station: the SoftPLC controller is installed atop a mountain and uses the A-Series I/O to monitor weather conditions (eg: temperature, wind speed/direction, humidity), which are made available to the public via a SoftPLC-based web page.

  • Overview

    A-Series I/O modules are a family of compact and networkable data acquisition and control modules, with a wide range of available analog and digital input/output signal types. All modules are designed for reliable operation in harsh environments and are equipped with isolation and failure protection, and high resistance against noise-interference. The "robust" serial modules (Models ASIO-41xx) can operate in temperatures from -40 to 85°C.

    Ethernet modules are available for ModbusTCP (Models AEIO-60xx), EthernetIP (Models AEIO-61xxEI) and ProfiNet (Models AEIO-61xxPN) protocols. Dual Ethernet port modules (Models AEIO-62xx, AEIO-61xxEI, AEIO-61xxPN) can be easily daisy-chained without the need for ethernet switches.

    The Serial modules (Models ASIO-4xxx) use RS-485, the industry's most widely used bi-directional, balanced transmission line standard. Some serial modules support the ModbusRTU protocol, while all modules also support a proprietary serial protocol for which SoftPLC Corporation has developed drivers for our SoftPLC controllers.

    All modules include these standard features:

    • Mounting Options - DIN-rail (side-by-side or piggy-back) or panel/wall mount
    • Removable screw terminals for signal wires to replace module without re-wiring
    • Wide input power ranges (eg: 10-30VDC)
    • Low power consumption
    • LED's for ease in troubleshooting wiring and communication network
    • Watchdog timer supervisory function automatically resets modules in the event of system failure
  • Specifications
