General Features of the Multi-Function Online Expansion Card
The Multi-Function Network IO Expansion Card is engineered for industrial environments, supporting seamless integration with PLCs via the Modbus protocol. This online IO card enables reliable control and monitoring in industrial automation systems. Equipped with four 4-20mA analog input ports, it connects easily to a wide range of 4-20mA sensors and transmitters for real-time process monitoring.
The device features two temperature and humidity sensors and two temperature sensors, designed for flexible installation with extended cable lengths (up to 10 meters for T&H sensors, 15 meters for temperature sensors). The card is DIN rail and panel-mount ready, with custom control panel design available upon request.
Multiple monitoring and control methods are supported: access device data online via a built-in web interface, connect with standard monitoring software such as Zabbix using Modbus and open protocols, or integrate with BRNIT cloud servers for centralized, IoT-based monitoring. Mobile app support provides parameter monitoring, logging, and configuration from anywhere. Optional GSM module offers remote communication and data acquisition over cellular networks.
For users requiring similar functionality with fewer features, the PC301 Network Relay Controller Card offers 8 relays with Modbus and PLC compatibility, and Ethernet connectivity via LAN. Alternatively, the PC301W Wireless Relay Board provides 4 relays and WiFi-based internet access for wireless automation.
