iSMA-B-4U4O-H

Multiprotocol I/O module with 4 universal inputs, 4 digital outputs, HOA switches and built-in HVAC and light applications.

Multiprotocol I/O Module in a Compact Size with Built-in HVAC and Light Applications
Powerful I/O module that works as a 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. The module is equipped with HVAC and light applications that control the output based on the input measurement.

4 Universal Inputs
Support for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input.

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

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

Built-in HVAC and Light Applications
Light, cooling, and heating configurable algorithms make the module applicable as a standalone controller.

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.
