WZ_SIGNAL signal generator is mainly used for debugging of industrial field PLC, process instrumentation, electric valve and so forth. Its easy to use with a friendly Chinese character operation interface. The signal generator is small and light but has a long standby time.Features Internal reverse and overcurrent protection, 30V protection voltage.Built in one single 7V lithium battery power supply; the using time varies, based on the usage (It can be more than 6 hours with 20mA continuous output).With internal battery voltage hint, (UV light)when the undervoltage light is on, please turn off the charging.Do not use for a long time, please charge once every two months.Charge with micro USB.Operating temperature range 0 50 degrees Celsius.Custom Function In order to facilitate on site debugging, the upper and lower limits of the output signal can be set according to the requirements of the equipment. The active 4 20mA output upper and lower limits, passive 4 20mA output upper and lower limits, and 0 12V output upper and lower limits can be set separately, and this function can be freely put on and off for field application.Automatic Output Function This function can automatically change the output mode according to the program. It can be automatically output only by setting the parameters, which is used for aging and automatic testing of valves and other equipment.This function consists of the following parts automatic mode, cycle number, initial value, incremental value, decrement value, incremental time, decrement time, starting point delay, endpoint delay, and end value. For active current, passive current, and voltage output, there are separate setting parameters to facilitate the setting of various output signals.VC Conversion Function This function is mainly used for some temporary voltage and current conversion, such as converting 0 10V input to 4 20mA output.VC active conversion converts the voltage signal input into an active current signal output VC passive conversion converts the voltage signal input into a passive current signal outputC V conversion converts the current input signal into a voltage signal outputThe function rules consist of several parts VC conversion switch, conversion mode, voltage upper limit, voltage lower limit, current upper limit, current lower limit, and overrange.Specifications Name Signal GeneratorActive current output range 0 24mA; resolution 0.01mA; maximum load 750Passive current output range 0 24mA; resolution 0.01mA; external power supply up to 30V.Voltage output range 0 12V; resolution 0.01V; maximum current 30mA24V voltage output drive current 24mA.Current input measurement range 0 24mA; resolution 0.01mA; input impedance 100Voltage input measurement range 0 30V; resolution 0.01V; input impedance 5MOperating environment 0C 50CProtection voltage 30VItem size 90 * 70 * 28mm / 54 * 76 * 10inPackage size 150 * 100 * 80mm / 91 * 94 * 15inPackage weight 160g / 64ouncePackage list 1 * Signal Generator3 * Test Cable1) We accept Alipay, West Union, TT.All major credit cards are accepted through secure payment processor ESCROW.2) Payment must be made within 3 days of order.3) If you can't checkout immediately after auction close, please wait for a few minutes and retry Payments must be completed within 3 days.
