The TCW242 is an industrial-grade IoT (Internet of Things) module that offers advanced monitoring and control capabilities for industrial applications. Equipped with Ethernet connectivity and data logging functionality, this device allows users to easily monitor and analyze a wide range of parameters. The device features 4 digital inputs, 4 analog inputs, an RS-485 interface for connecting MODBUS RTU sensors, and 4 relays. The analog inputs can be configured to work in either current loop (0-20mA) or voltage (0-10V) modes, providing flexibility in monitoring different types of parameters. The TCW242 supports up to 24 Teracom and third-party MODBUS RTU sensors, allowing users to configure up to 24 independent monitoring channels. Each channel can be set up using up to 2 input parameters and/or constants and can be configured as either discrete or general channels. This provides users with a wide range of monitoring options. In addition to monitoring capabilities, the device also offers robust alarm functionality. Users can configure up to 24 independent alarms with 5 different user-selectable states. Each alarm can be set up using up to 2 limits and hysteresis and can be assigned to a specific channel. In this case, in an alarm state, the assigned channel is colored on the monitoring page and graphs, providing users with a visual indication of the alarm state. The device also supports a variety of communication protocols for M2M (machine-to-machine) communication, including SNMP, HTTP API, MODBUS TCP/IP, and MQTT. These protocols allow for easy integration with other industrial systems and devices, providing users with a wide range of options for data analysis and control. Overall, the TCW242 industrial IoT module is a powerful and versatile device that offers advanced monitoring and control capabilities for industrial applications.
