Page 4: Introduction
This chapter provides basic information about device. Before starting, please read this manual carefully. P2520 two-channel current loop converter is designed to connect sensors with output 0-20 mA or 4-20 mA into Ethernet network. Current can be recalculated to physical value measured by the connected sensor. -

Page 9: Device Setup
IE-SNC-P2520-02 Chapter Device setup This chapter describes basic device configuration. There is a description of settings using web interface. Setup using web interface Web interface can be managed by the web browser. Main page will be shown when you insert device address into address bar of your web browser. - Page 10 IE-SNC-P2520-02 General Device name can be changed using item Device name. Measured values are stored into memory according to History storage interval field. After changing of this interval all history values will be cleared. Be aware that content of memory for history values is not preserved after device restart or power lost.
- Page 11 IE-SNC-P2520-02 Alarm limits For each measurement channel is possible to set upper and lower limits, time-delay for alarm activation (0 – 30000 s) and hysteresis for alarm clearing. Example of setting the limit to the upper alarm limit: In Point 1 the measured value exceeded the limit. From this time, the time-delay is counting.
- Page 12 IE-SNC-P2520-02 Channels Channel can be enabled or disabled for measuring using checkbox Enabled. Channel can be renamed, and unit of channel can be changed. Measured current is recalculated to physical representation according to selected linear equation. Number of decimal places is selectable.
