Multiprotocol I/O Module with a MAX number of Digital Outputs - a powerful addition to any building automation system

Digitalize buildings with reduced engineering time using the powerful 12 digital outputs module, which works as a remote I/O over IP with open protocols, BACnet IP and Modbus TCP/IP. Open protocols standard offers the versatility of installing the modules in both new and existing facilities, whether it is a system expansion or a retrofit. The maximum number of the most popular types of inputs or outputs allows the module to be a versatile controller extension, whether in a small or large facility.

12 relay outputs

Digital outputs equipped with normally open 3 A relays allow for direct control without additional relays.

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. Two Ethernet ports working in a switch mode allow for daisy chaining of multiple modules over the RJ45, which facilitates the cabling process and reduces engineering time.

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 confirms the excellent performance of communication using the BACnet protocol.
