مولتی متر خروجی RS485 ریشاب Rishabh سری Energy Meters مدل RISH EM 3490DS (LED)

Rish EM 3490 DS features two energy integrator Utility & Generator. In normal operation meter accumulates energy counts in utility register & when utility shutdowns and control input signal of (10 to 60V DC/ 20 to 300V AC) is present on generator sensor energy starts accumulating in Generator register.

It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485)

The secondary of external potential Transformer (PT) can be programmed on locally via front panel keys by entering into Programming mode or remotely via MODBUS (Rs485)

User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485). For single phase applications, single phase version is available.

The instrument has very low back depth (behind the panel) of less than 80 mm in spite of optional features like pulse output Onsite

User can set the display in auto scrolling mode or fixed screen mode locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485).

The instrument measures distorted waveform up to 15th Harmonic.

Simultaneous displays Utility and Generator parameters.

In case of power failure, the instrument memorizes the last displayed screen. The displayed screen will get memorized only if user keeps this screen for minimum 40 sec duration before power failure for fixed screen mode.

Customer can assign MODBUS register address as per his need for faster response time.

In case of power failure, the instrument memorizes the last energy count. Every 40 sec, the instrument updates the energy counter in the non-volatile memory.

Hour run records the number of hours load is connected. ON Hour is the period for which the auxiliary supply is ON. Number of Interruptions indicates the number of times the Auxiliary Supply was interrupted. All these parameters are displayed in both utility & generator mode.

This register holds the value before the last reset. The old value will be available when scrolled through screen.

The optional ModBus output enables the instrument to transmit all the measured parameters over standard MODBUS (RS485).

The instrument has optional pulse output one for Utility and another for Generator. The optional pulse output is a potential free, very fast acting relay contact which can be used to drive an external mechanical counter for energy measurement.

The instrument settings can be configured locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485).

Note: The MODBUS communication parameters can only be set locally via front panel keys in the Programming mode.
