Four-channel wall-mounted temperature meter И4

The four-channel meter И4-Н (wall-mounted version) is designed for measuring and controlling from 1 to 4 physical quantities and displaying the measured values on four built-in digital indicators.
И4 has four independent measurement channels and the ability to simultaneously indicate four values.
Produced only in the IP24 version: powered from a DC voltage source rated at 12..24 V.
И4-Н is designed for monitoring temperature, pressure, humidity, flow rate, or another physical quantity in several zones simultaneously (up to four) and to provide an alarm output signaling when any of the parameters go outside the set range. И4 is used as an alarm indicator in furnaces, drying chambers in the food, metallurgical, and other industries.

General functions and operating modes

• Measuring the temperature (or other physical quantities) of objects using standard sensors: resistance thermometers (temperature sensors) TSM (50M, 100M) and TSP (50P, 100P, Pt100, Pt500, Pt1000), thermocouples (TXK, TXA, TZHK, etc.), sensors with standardized current output AT (0..5 mA, 0..20 mA, 4..20 mA) and voltage output AN (0..1 V, 0..5 V, 0..10 V);
• Formation of an "Alarm" signal;
• Function for calculating and displaying the square root of the measured value (e.g., for instantaneous flow measurement from AN and AT sensors);
• Measurement scale scaling;
• Light indication of operating modes;
• Software modification of conversion characteristic parameters (slope, offset);
• Digital filtering of measurements (filter depth - up to 10 measurement periods);
• Changing the display update period of measured values;
• Digital calibration of input channels;
• Password protection of parameters;
• RS-485 ModBus RTU interface for recording measured values on a PC or working with PLC.
