The ISMA-B-4U4A-H-IP is a compact multiprotocol I/O module that operates over IP, supporting BACnet IP and Modbus TCP/IP protocols. This module suits distributed building automation systems, particularly in installations with limited space.

It features four universal inputs, accommodating over 20 types of temperature sensors, as well as voltage, resistance, current, and dry contact measurements. Each input delivers 16-bit resolution for accurate data capture. The four analog outputs provide 0-10 V DC control with a maximum load of 20 mA, suitable for various applications such as relay control.

Manual override switches are included for each analog output, enabling direct control when needed. The built-in Modbus TCP/IP to Modbus RTU/ASCII gateway supports integration of up to 128 Modbus slave devices, increasing system flexibility.

Configuration is easy, with options for BACnet, Modbus, or a built-in web server. The mini USB port allows for initial setup without an external power source. Fast addressing capabilities and LED indicators for input and output status streamline installation and monitoring.

This module serves as a reliable solution for control and monitoring in building automation, fitting well with existing BMS infrastructures.
