The ISMA-B-4I4O-H-IP is a compact multi-protocol I/O module that operates over IP with BACnet and Modbus TCP/IP protocols. This module fits into tight spaces while providing essential control capabilities. It features four digital inputs and four digital outputs for efficient monitoring and control of various equipment in your building management system.

Each digital input supports dry contact monitoring and includes a 100 Hz fast pulse counter with an override function, storing real-time values in EEPROM memory. The digital outputs come with normally open relays rated at 3 A, allowing direct control of connected devices. Manual override switches for each output provide local control.

The ISMA-B-4I4O-H-IP includes built-in light applications for standalone control tasks. Its Modbus TCP/IP to Modbus RTU/ASCII gateway supports integration of up to 128 Modbus slave devices, which enhances system scalability. Configuration is straightforward, using a built-in web server and a complimentary configuration tool, with support for BACnet and Modbus protocols.

Powered via a USB port, this module simplifies local testing and updates. The ISMA-B-4I4O-H-IP is a reliable solution for modern building automation, combining a compact design with powerful functionality.
