The ISMA iSMA-B-8U is a compact multiprotocol I/O module for building automation systems. It includes 8 universal inputs that support various sensor types, accommodating over 20 temperature sensors, and measuring voltage, resistance, current, and dry contact signals. This module uses RS485 communication and works with BACnet MS/TP and Modbus RTU/ASCII protocols, making it a solid choice for existing BMS infrastructures.

Installation is easy due to its compact design and configuration via DIP switches. The iSMA-B-8U features quick addressing with rotary switches, simplifying the commissioning process. A built-in mini USB port allows local testing and initial configuration without an external power supply. This feature improves deployment efficiency in space-constrained areas.

The module supports various applications, from HVAC systems to lighting control, and can operate independently with built-in control algorithms in selected models. Manual override switches provide direct control of field devices, enhancing operational flexibility.

Equipped with a high-end RS485 transceiver, the iSMA-B-8U can communicate with up to 128 devices on a single bus. This capability suits distributed I/O and local control applications, enabling effective monitoring and management of connected systems. The ISMA iSMA-B-8U is a versatile option for professionals aiming to enhance their building automation capabilities.
