iSMA-B-4O-H

Multiprotocol I/O Module in a Compact Size with High Power Relays
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. The module is equipped with 8 A relay outputs.

4 Digital Outputs
Digital outputs equipped with NC/NO 8 A relays allow for a direct control of high power loads.

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

Simplified Configuration and Commissioning Process
The module allows for seamless configuration over BACnet, Modbus or dedicated free of charge tool. The ability to be powered from a USB port facilitates local testing and a straightforward updating process, and the high-end RS485 transceiver allows up to 128 devices to communicate reliably with the client on a single bus.

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.
