Measure all the data of 3-Phase 3 ways outputs of 4-20mA or 0-5V CE MARK (EMC, LVD), RoHS Mark

1. General

BD4EA programmable power transmitter specializes in measuring the data of all kinds of AC networks. It can be connected with the control equipment in measuring and controlling system. They comply EN 61326:2006 and EN 61010-1:2001.

They are a kind of programmable transmitter. The user can program it by front or PC software. They have many option functions. They can be equipped RS-485 communication Modbus-RTU; or they can output up to 4 analog signals.

They are a kind of analyzer with excellent cost performance, since they regroup the functions of traditional electric transmitter and digital meters. Therefore they are widely being used in kinds of control system, SCADA system and power management system.
