Web Enabled 4-20 mA Input Controller

RST-5001 module has been developed to provide a cost-effective solution for the monitoring of local and remote tanks or processes. It can accept any 4-20 mA output from a sensor and provide a method of calculating and reporting the level or volume of a vessel. It can also be set up to display and record user-defined units such as PSI, Temp, PH, etc. Readings are reported to a secure database on the Internet via an existing network connection.

Programmed via internal web page; no special programming software required. Two programmable solid-state relays (130 mA max.) for process control or alarm points

Web Enabled 4-20 mA Input Controller

Some Features

• Compatible with any 4-20 mA device
• Employs Power Over Ethernet (POE)
• 24 VDC power for sensor
• Can use standard 24 VDC supply
• Din-rail mounting
