Product Description

DC Digital Voltmeter AMC72L-DV

Products Description

AMC series programmable intelligent meters,adopting AC sampling technology,can directly or indirectly measure electric voltage and current of single phase or three phase grid. It can be used for local display,and connecting industrial control device to form measuring control system. This series of meters have RS-485 port,adopt Modbus-RTU protocol. Analog output,alarm output,switching input/output can be selected. Based on different request,by pressing the keys,parameters of ratio,alarm,communication etc. can be modified.

● Measurement: 1-circuit DC Voltage ● Accuracy: 0.5% ● Rated Current: 0~10V DC (via Transducer); 300V or 1000V DC (direct connect) ● Power Supply: 85~265V AC/DC ● Alarm Output: Low&High Current Alarm ● Analog Output: 4~20mA DC ● Standard&Certificate: CE Certificates

● DI/DO Function: 2-channel DI&2-channel DO optional ● Communication: RS485 (MODBUS-RTU) optional
