iSMA-B-4U4O-H-IP

Multiprotocol I/O module with 4 universal inputs, 4 digital outputs, HOA switches, IP connectivity, and built-in Modbus TCP/IP to Modbus RTU/ASCII gateway. 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 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 HVAC and light applications that control the output based on the input measurement.

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 enables a straightforward updating process.

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.

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.

 

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.
