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.
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.
