PROCESS INDICATOR
The frequency input is 1Hz~6KHz, the input signal is a sine wave
˙ The operation buttons are built-in to prevent users from arbitrary operation or incorrect setting, which may cause
abnormal operation of the equipment
˙ 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-site
˙ On board terminal design, no quality issue, installation depth is only 73mm
CM1-F is an economical and simple frequency meter with a 20mm 5-digit
LED display, and the display range can be set by pressing the button. Antiinterference design, reliable quality, simple installation and operation.
At the same time, it has 2 sets of relay output or 1 set of analog output or 1
set of RS485 (Modbus RTU mode) communication ports for selection.
The built-in design of the operation buttons can avoid human misoperation
and is suitable for various mechanical use.
