iSMA-B-4U4A-H-IP

Multiprotocol I/O module with 4 universal inputs, 4 analog outputs, hand output control, IP connectivity, and built-in Modbus TCP/IP to Modbus RTU/ASCII gateway.

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 confirm the excellent performance of communication using the BACnet protocol.
Reliability of operation is confirmed by UL testing, certified by Underwriters Laboratories.
