PROGRAMMABLE DIGITAL METER OF D.C. CURRENT, D.C. VOLTAGE
DESCRIPTION OF PROGRAMMABLE DIGITAL METER OF D.C. CURRENT, D.C. VOLTAGE
The N30H meter is a programmable digital panel meter destined for the measurement of d.c. voltage or d.c. current. Additionally, the meter enables the indication of the current time. The readout field is a LED display, which allows the exposition of results in colours: red, green and orange. The measured input signal can be arbitrary converted by means of a 21-point individual characteristic.
Features of the N30H meter:
- l display colour individually programmed in three intervals,
- l programmable thresholds of displayed overflows,
- l 2 NOC relay alarms operating in 6 modes,
- l 2 switched relay alarms with a switching contact operating
- in 6 modes (option),
- l signaling of the measuring range overflow,
- l automatic setting of the decimal point,
- l programming of alarm and analog outputs with the reaction
- on the chosen input quantity (main or auxiliary input),
- l real-time clock with the function of the clock supply support
- in case of the meter supply decay,
- l programmed averaging time – function of walking window with the
- averaging time up to 1 hour,
- l monitoring of set parameter values,
- l interlocking of introduced parameters by means of a password,
- l recount of the measured quantity on the base of a 21-point
- individual characteristic,
- l service of the interface with MODBUS protocol in the
- RTU mode (option),
- l conversion of the measured value into a standard – programmable
- current or voltage signal (option),
- l highlight of any measuring unit acc. to the order.
