Configurable I/O BACnet/IP or Modbus TCP

 

 

Product Overview

The configurable I/O modules provide universal inputs that support temperature, analog, resistance and binary in a single module. For applications not requiring universal inputs there are modules with discrete inputs that support contact closure and retentive pulse counting at 100Hz. Additional modules supply a mix of universal and/or discrete inputs with relay outputs and analog outputs. A single module supports BACnet MS/TP or Modbus RTU/ASCII with a simple dip switch selection.

The modules are housed in a compact UL approved self-extinguishing plastic enclosure, rated for operation in -10°C to +50°C (14°F to 122°F) environments and DIN rail or panel mounted typically in a control enclosure. All modules use half-wave rectified low voltage power supply that allows for sharing of power with other 24 VAC/VDC devices. All IP version modules are equipped with a built-in Modbus TCP/IP for RS485 gateway which allows for establishing a connection with RS485, additional I/O modules, or 3rd party devices.

Configuration Software

The iSMA Configurator has been designed to perform configuration, firmware updates and diagnostics on the configurable I/O. The free downloadable software provides communication with the use of USB, BACnet MS/TP, Modbus RTU, BACnet IP or Modbus TCP. It allows monitoring the device's operating parameters, remote change of I/O module output states and input modes. This simple and intuitive to use software is the convenient tool for every configurable I/O user. This software is intended for Windows operating system and can be run on Windows 7, 8 or 10. There is no need to install any additional software or drivers to run iSMA Configurator.

• Connection by USB cable without powering the module
• Upgrade firmware, reset module, reload module and load default settings
• Monitor digital inputs/pulse counter values
• Configure universal inputs for temp, analog, contact closure
• Establish COV increments
• Configure communication parameters
• Save configuration file, load configuration file
• Supported five types of communication: Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, USB
• Web based browser configuration
