Eight-channel meter I8

The eight-channel meter I8-N (wall-mounted) is designed to measure and control from 1 to 8 physical quantities and display the measured values on the built-in eight digital indicators.
I8 has eight independent measuring channels and the ability to display eight values simultaneously.
Produced only in version IP24: power supply from a constant voltage source = 12..24V.
I8 is designed to control temperature, pressure, humidity, flow rate or other physical quantity in several zones simultaneously (up to 8) and an alarm output signaling the exit of any of the monitored parameters beyond the specified limits.
I8 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 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);
• polling devices in the network via the RS-485 interface using the ModBus protocol (the device acts as a master);
• 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;
• 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.
