Multiprotocol I/O Module in a Compact Size

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.

4 universal inputs

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

4 Analog Outputs

0-10 V DC control with 10 mA accuracy, PWM modes, and a maximum load of up to 20 mA to power external relays makes the output suitable for a variety of scenarios.

Manual Override Switches

Each analog output can be manually overdriven using a dedicated manual potentiometer.

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.

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.
