The ISMA-B-4U4O-H-IP is an I/O module that supports BACnet IP and Modbus TCP/IP protocols. Its compact design fits installations where space is limited, while its capabilities provide effective control for HVAC and lighting applications.

This module includes four universal inputs, capable of handling over 20 types of temperature sensors and measuring voltage, resistance, current, and dry contacts. Each input offers 16-bit resolution for accurate data collection. The module also has four digital outputs with 3 A relays for direct load control. This setup allows efficient system management without needing extra relays.

Each output features manual override switches for local control when required. The built-in Modbus TCP/IP to Modbus RTU/ASCII gateway integrates with up to 128 Modbus slave devices, expanding your system across both IP and RS485 networks.

Configuration is simple with DIP switches for protocol selection and rotary switches for quick addressing. A mini USB port supplies power for initial setup, enabling rapid deployment and local testing. LED indicators for input and output status confirm reliable operation in various building automation applications.
