Open type 200A AC current sensor

The open type BA series products apply the principle of electromagnetic induction to measure the AC current in the power grid in real time. They use constant current and linear compensation technology to isolate and transform it into a standard DC signal output. DC12V or 24V safe voltage can be widely used in the field of industrial automation.

1、 Model Description

2、 Technical parameters

3、 External dimensions

V+- Positive pole of power supply (note that the positive pole of power supply cannot be connected in reverse to ground)

V - Power Ground

OUT - Analog output negative

OUT+- Analog output positive

DO -, DO+- switch interface

A. B-485 interface

The cable is a perforated input

Definition of indicator light:

RUN: Running normally. When there is no 485 communication connection, the RUN light displays green and flashes once every 1 second; When the current sensor is successfully connected to 485 communication, the RUN light flashes rapidly;

Alarm: After turning on the alarm switch, when the input current reaches 120% of the current sensor range, the red light of the Alarm light remains on, and the relay output is closed; When the input current drops below 110% of the sensor range, the alarm light goes out. If the alarm switch is not turned on, the alarm will not light up and the relay will not close.

Note:

(1) The instrument wiring adopts detachable terminal blocks, and it is recommended to use shielded wires with a cross-sectional area of 0.75mm ² for connecting wires on the power, output, RS485 communication, and switch interface sides.

(2) The specific wiring shall be based on the wiring diagram on the physical casing.
