The IN301 Online 8-Channel Digital Input Card is a versatile solution for controlling and managing equipment across a wide range of industries. This advanced card is designed to optimize processes and enhance system efficiency through real-time digital monitoring and control. With robust features and reliable network communication—supporting both Modbus protocol and standard Ethernet connectivity—the IN301 enables continuous online monitoring, remote management, and integration with IoT platforms. Users can monitor system status and alarms directly via web or mobile applications.
Engineered for industrial automation and electronic system management, the IN301 8-Channel Digital Input Card is fully compatible with diverse digital sensors and contact-based devices. Its eight independent digital input channels collect and transmit data to control systems, providing real-time insights and streamlined management. The card is equipped with an RS485 port for Modbus RTU communication and easily integrates with PLCs and SCADA networks. Ideal for smart monitoring of motion, smoke, temperature, access control, or any contact output, the IN301 ensures seamless connectivity for modern industrial and building automation applications.
The IN301 8-Channel Digital Input Card is an essential component for automation systems, server rooms, data centers, industrial automation, and commercial projects. It enables continuous, intelligent digital input monitoring for smart and real-time system oversight. Equipped with a network communication interface (Ethernet port), the IN301 provides instant online data transmission and supports both Modbus TCP and Modbus RTU protocols—ensuring seamless integration with automation systems, a wide variety of sensors, and third-party controllers. With RS485 connectivity, the card acts as a flexible Modbus digital input card for direct PLC connection and SCADA implementation. The IN301 also offers SNMP and JSON protocol support, making it fully compatible with leading network monitoring software such as Zabbix and SolarWinds.
This network-enabled digital input card supports connection to a range of relay-based or contact output sensors, including smoke detectors, temperature sensors, PIR motion sensors, micro switches, and gas detectors. Any device with relay or contact output can be monitored through the IN301 card. Additionally, an onboard relay output allows direct device control and rapid response to alarms, enabling immediate, automated action and smart process management.
As an all-in-one solution designed to meet the needs of industrial automation and smart monitoring, the IN301 digital input card is ideal for enhancing security, automation, and management systems in modern facilities. For projects requiring more relays, GSM/SIM card connectivity, or extended IO capability, we recommend the Multi-Purpose Network IO Expansion Card. For comprehensive online environmental monitoring and control, integrate the Online Environmental Monitoring Transmitter alongside the IN301 for complete smart area management. Together, these devices provide seamless, real-time monitoring and intelligent control for server rooms, data centers, and office environments.
