CM1-VA 4 Digits Voltage/Current Meter

Description

CM1 series Indicator has been designed in simple function and 4 digital 20.0mm LED displays with economic cost.

They can be programmed by tact switches that are hidden in backside of front bezel.

They are also available option of 2 Relay outputs, 1 Analog output or 1 RS485 (Modbus RTU Mode) interface with versatile functions such as control, alarm, re-transmission or communication for a wide range of industrial applications.

 

Features 

■ Measuring AC / DC Voltage 50mV~600VAC / DC Current 1.999mA~10A

■ The operation buttons are built-in to prevent users from arbitrary operation or incorrect setting, which may cause abnormal operation of the equipment

■ The display value can be adjusted slightly with the "field measurement signal"

■ The output can option relays or analog output or RS485 (Modbus RTU mode)

■ Relay function in addition to start delay, active delay, delay off and active hold

■ Analog output voltage signal range can be switched (0~10V/0~5V/1 ~5V) or current signal range can be switched (0~10mA/0~20mA/4~20mA)

■ The analog output signal is free to set the corresponding display range (Span-50%) and can be fine-tuned on-sit

■ On board terminal design, no quality issue; installation depth is only 73mm

 

Applications

■ Testing Equipment for Volt/Current Measuring

■ MCC panel, Machinery, Switch gear... for Voltage or Current Measuring
