INT4 range of Digital Panel Meter Counters and Rate Meters
The Intuitive Range of digital panel ratemeters, totalizers and controllers is ideal for industrial counting, conveyor speed measurement, RPM measurement, Frequency measurement, angle, position or length measurement.
INT4-C digital panel meter totaliser / counter / RPM / ratemeter - easy to use!
The INT4-C is our most popular 1/8 DIN panel meter which accepts standard pulse signals from NPN, PNP, contact closure, 24VDC and 5VDC devices and encoders.
Standard Features...
4 inputs for totalising
Up and Down count inputs
Gate input for controlled counting
Quadrature input for angle / position / length measurements
RPM measurement with 1 - 10000 pulses per rev
Production ratemeter mode includes rolling averaging
Wide range of input sensor types accepted
Precise ...
This digital panel meter is easy to use and has high precision and stability. You can set the display to have 2, 3, 4, 5 or 6 digits, depending on the type of measurement you want to make. You can also set the decimal point position.
Flexible ...
This panel meter can be fitted with isolated output signal modules to add control and data sharing functions.
Tamper Proof ...
This digital panel meter is also available with a plain front panel. All settings can be locked to prevent changes after commissioning.
The small window in the bottom right can have text such as RPM, m/min, Hz, bottles etc.
The display colour is available in red or green.
