Description

Measurement and control function

1.Measurement function: provide three-phase voltage, three-phase current, active power, reactive power, power factor, frequency.

2.Input: provide standard 24-way input.

3.Outputs: Standard 5 relay outputs are provided, with 7 open contacts. 4.Remote control: Provide remote control trip and close operation of circuit breaker switch.

5.Metering function. Provide hardware forward active, forward reactive, reverse active, reverse reactive energy metering functions, and provide forward active and forward reactive energy pulse output functions. At the same time, the active power and reactive power calculated by the device can be used to accumulate active and reactive power.

6.Operation circuit: including jumping, closing, jumping monitoring, closing monitoring, jumping signal output, closing signal output, control circuit disconnection output, protection tripping output, remote tripping output, remote closing output, manual Trip input, manual closing input, DCS trip input, protection trip input, 2-way position combined trip or protection combined trip output, etc.

7.4-20mA output: The device provides 1 channel of 4-20mA output, and 2 channels of 4-20mA output are optional, and the corresponding measurement and multiple can be set arbitrarily.

8. Motor management functions

• Motor starting time, max starting current, recording of starting process
• Motor accumulative running time, last running time
• Motor cumulative opening times, cumulative closing times
