Multiprotocol I/O Module in a Compact Size

Powerful I/O module that works asa remote I/O over a serial port with open protocols, BACnet MS/TP and Modbus RTU/ASCII. 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.

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.
