The ISMA ISMA-B-4TO-H-IP is a compact multiprotocol I/O module designed for building automation. It operates over Ethernet using BACnet IP and Modbus TCP/IP protocols, allowing easy integration with existing systems. Its small dimensions enable installation in tight spaces where additional I/O points are required.

This module features four Triac outputs, each capable of handling loads up to 0.5 A, providing silent control of AC current. Manual override switches for each output allow for direct local control. The Modbus TCP/IP to Modbus RTU/ASCII gateway enables integration with up to 128 Modbus slave devices, expanding system capabilities.

Configuration is simple, with DIP switch protocol selection and rotary switch addressing. A built-in mini USB port supports initial setup without needing an external power source. This module suits various applications, including HVAC and lighting control, and supports timer relay modes for occupancy-based strategies.

The ISMA-B-4TO-H-IP is compatible with multiple temperature sensors, including NTC and PT1000, and supports digital inputs with fast counting capabilities. With Ethernet connectivity and reliable performance, this module fits well in modern building automation systems.
