The ISMA ISMA-B-4O-H-IP is a compact multi-protocol I/O module for remote I/O communication over IP, using BACnet IP and Modbus TCP/IP protocols. It features 8 A relay outputs, suitable for controlling high power loads across various applications.

With four digital outputs supported by NC/NO relays, the ISMA-B-4O-H-IP provides reliable control of devices and systems. Each output includes manual override switches for local control, adding flexibility in operation.

A Modbus TCP/IP to Modbus RTU/ASCII gateway on the COM1 port integrates up to 128 Modbus slave devices. This allows for expansion of existing network infrastructures without complications. The ISMA-B-4O-H-IP fits projects that require easy integration with various devices.

Configuration is straightforward, with setup options via BACnet, Modbus, or a dedicated free tool. The mini USB port supports local testing and updates. This module suits distributed building automation systems, especially where space is limited but functionality is essential.
