Tips: What are relay output and analog quantity output?
Relay output is a kind of on/off output, and outputs 0 and 1 through ON and OFF status. Although relay output can directly connect to PLC, it should be noted that the relay is mechanical with low speed. So it is not suitable to use at high speed signal. And relay output is ON/OFF output and is not suitable for continuously changing analog signal. In addition, the relay is only a switch. The voltage input can't be used directly when it needs to pull up or pull down, and the pull up and drop-down resistance is required.Analog output refers to output of continuously changing state. For example, 4-20mA current signal and a 0-5V voltage signal are continuous signals. In the instrument, the 4-20mA output represents the corresponding value of setting range. For example, in a thermometer (0~600℃), when the temperature is 0℃, the analog output of the instrument is 4mA. When the temperature is 300℃, the analog output of the instrument is 12mA.
Freezer temperature controller has dual digital 4 LED display, on-off control/PID control, single RTD input Pt100 (-200.0~600.0℃), relay output, miniature needle printer for temperature record in medicine freezer and cold chain.
