Wall meters with logger function I4l, I8l

Wall-mounted meters with logger function are designed for measurement, simultaneous display of input values on built-in digital indicators and recording measured values in the non-volatile memory of the device at specified time intervals.
It is possible to manufacture four-channel and eight-channel meters with a logger function.
The meters are produced only in the IP24 version: power supply from a constant voltage source = 12..24V.
I4l and I8l are designed to control temperature, pressure, humidity, flow or other physical quantity in several zones simultaneously (up to 4 for I4l and up to 8 for I8l) and have an alarm output that signals if any of the monitored parameters exceeds the specified limits.

General functions and operating modes

• measurement of temperature (or other physical quantities) of objects using resistance thermocouples (temperature sensors) ТСМ (50М, 100М) and ТСП (50П, 100П, Pt100, Pt500, Pt1000), thermocouples (ТХК, ТХА, ТЖК, etc.), sensors with unified output signal of current АТ (0..5 mA, 0..20 mA, 4..20 mA) and voltage АН (0..1 V, 0..5 V, 0..10 V);
• formation of the "Emergency" signal (with the possibility of issuing a control signal to the output stage) when the measured physical quantity is outside the specified alarm range, as well as when the input sensors are open or short-circuited;
• the function of calculating and indicating the square root of the measured value (for example, for measuring the instantaneous flow rate from the sensors АН and АТ);
• scaling of the scale of measurements;
• light indication of operating modes;
• recording measured values into the non-volatile memory of the device at specified time intervals;
• software change of parameters of transformation characteristics (slope, offset);
• digital filtering of measurements (filter depth - up to 10 measurement periods);
• change of indication period of measured values;
• digital calibration of input channels;
• password protection of parameters;
• The device has 2Mb of memory, which allows you to store 5459 records along the skin canal for I8l (10918 records for I4l);
• RS-485 ModBus RTU interface for recording measured values on a PC or for working with a PLC.
