iSMA-B-4TO-H-IP

Multiprotocol I/O Module in a Compact Size
Powerful I/O module that works as a remote I/O over IP with open protocols, BACnet IP and Modbus TCP/IP. A compact size and ease of installation allow the module to be fitted even into limited space installations.

4 Triac Outputs
Silent control of AC current with four solid-state outputs with PWM mode and up to 0.5 A load.

Manual Override Switches
Each output can be manually overridden using a dedicated hand operating switch.

Modbus TCP/IP to Modbus RTU/ASCII Gateway
Built-in Modbus gateway on the COM1 port enables integration of up to 128 Modbus slave devices to the IP layer.

Simplified Configuration and Commissioning Process
The module allows for seamless configuration over BACnet, Modbus, built-in web server or dedicated free of charge tool. The ability to be powered from a USB port facilitates local testing and a straightforward updating process.

Quality and Reliability Confirmed by Certificates
iSMA CONTROLLI is a long-standing member of the BACnet community. The experience in developing high quality products and the BTL (BACnet Test Laboratory) certification confirm the excellent performance of communication using the BACnet protocol.
Reliability of operation is confirmed by UL testing, certified by Underwriters Laboratories.
