Wall-mounted meters with logger function И4л, И8л

Wall-mounted meters with logger function И4л, И8л are designed to measure, simultaneously display on built-in digital indicators the input values, and record measured values at specified time intervals into the device's independent memory.
It is possible to manufacture four-channel and eight-channel meters with Logger function.
The meters are produced exclusively in IP24 version: powered by a 12..24V DC power source.
И4л and И8л are intended for monitoring temperature, pressure, humidity, flow, or another physical quantity in several zones simultaneously (up to 4 for И4л and up to 8 for И8л) and have an alarm output signaling the excursion of any monitored parameter beyond set limits.

General functions and operating modes

• measuring object temperature using resistance thermometers (temperature sensors) TCM (50M, 100M) and TSP (50P, 100P, Pt100, Pt500, Pt1000), thermocouples (TXK, TXA, TZhK, etc.), sensors with standardized output current signal AT (0..5 mA, 0..20 mA, 4..20 mA) and voltage AN (0..1 V, 0..5 V, 0..10 V);
• generation of an "Alarm" signal (with the ability to output a control signal to the output stage) when the measured physical quantity goes beyond the preset alarm range, as well as in case of break or short circuit in input sensors;
• function to calculate and display the square root of the measured value (e.g., for determining instantaneous flow from AN and AT sensors);
• scaling of measurement scale;
• light indication of operating modes;
• recording measured values into the device's independent memory at set time intervals;
• software adjustment of the conversion characteristic parameters (slope, offset);
• digital filtering of measurements (filter depth – up to 10 measurement periods);
• changing the display update rate of measured values;
• digital calibration of input channels;
• password protection of parameters;
• the device has 2 MB memory, allowing to store 5459 records per channel for И8л (10918 records for И4л);
• RS-485 ModBus RTU interface for registering measured values on a PC or working with PLC.
