Monitor and Control 4 Analog Inputs Over Copper or Fiber Ethernet with Real-Time Alerts
The Smart 4 Analog (4~20mA) Input Sensor is a programmable Ethernet I/O controller that interfaces with industrial process control instruments such as environmental sensors, flow meters, level transmitters, and actuators.
Each of the Analog Input channels are configurable through a built-in web management portal, and can be integrated with network management systems, industrial control systems, Internet of Things (IoT) frameworks, and REST-integrated automation platforms.
The Smart 4 Analog Input Sensor support TLS/SSL encryption, IEEE 802.1X via RADIUS authentication (AAA), role based access control (RBAC), and event logging. Its versatile 2-port (1xRJ45, 1xSFP) Ethernet interface offers network access redundancy and segmentation.
Each device can operate as a standalone unit, independently monitoring and controlling the value of their 4 analog inputs or 4 outputs, or paired together with our Smart 4 Analog (4~20mA) Output over a secure TLS/SSL-encrypted tunnel.
This System Pairing feature allows Input Sensors to transmit 4~20mA signals across an Ethernet network to one or multiple remote locations.
