Four-channel wall-mounted temperature meter I4

Four-channel meter I4-N (wall-mounted) is designed to measure and control from 1 to 4 physical quantities and display the measured values on four built-in digital indicators.
I4 has four independent measuring channels and the ability to simultaneously display four values.
Produced only in the IP24 version: power supply from a constant voltage source with a nominal value of 12..24V.
I4-N is designed to control temperature, pressure, humidity, flow rate or other physical quantity in several zones simultaneously (up to 4) and an alarm output signaling the exit of any of the monitored parameters beyond the specified limits. I4 is used as an alarm device in ovens, drying chambers in the food, metallurgical and other industries.

General functions and operating modes

• measurement of temperature (or other physical quantities) of objects using standard sensors: resistance thermocouples (temperature sensors) ТСМ (50М, 100М) and ТСП (50П, 100П, Pt100, Pt500, Pt1000), thermocouples (ТХК, ТХА, ТЖК, etc.) ), sensors with a 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;
• 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;
• 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;
• RS-485 ModBus RTU interface for recording measured values on a PC or for working with a PLC.
