P-1 relay mode

Time for timing relay or relays , timing range: 0-999 seconds or 0-999 minutes, can be switched ;

Loop execution :

By the time the relay mode, the user can set the relay pull- time T1 and release time T2, T1 is set to 3 seconds for example , T2 for seven seconds , then relay run will first perform three seconds pull further seven seconds of time release , and so on .

When you set the time value of T1 and T2 , the system will power off to save the set value, the next time you run P-2 mode will automatically be loaded T1 time to wait to start running .

After pressing the SET to set the time value of T1 and T2 state , press SET key to set the execution cycle times , maximum 999 times. The number is set to 0 infinite loop execution . When the timer is running , press the SET button for three seconds byTiming values are displayedSwitch to theCount the number of times the loopDisplay .

Single execution timing :

If only set T1 ( pull-in time ), T2 ( release time ) is 0, the relay timed run after T1 time to stop , no cycle operation , this time can be used as a timer , T1 time timing is complete, the relay is released , At this point press the ENTER key , the system re- T1 time to start timing .

If T1 ( pull- time ) is set to 0 , the relay has been in a released state ( does not start running normally closed switched on , normally open points off ) .

Power input terminals using 5.08mm , follow product instructions and wiring operation , For more detailed electronic version of the specification , issued after the shoot -mail or online request .

Voltage relay module P-2Type

Under voltage relay mode and temperature control relay mode, the user can set the upper control limit value when the detected voltage or temperature exceeds the upper limit of the relay pull changes from release until the voltage drops below the lower limit is set only pull again relay , this feature can be used for voltage monitoring , temperature control , etc. , can also be used as a DC voltage meter and thermometer , voltmeter display range : default shipping is 0-99.9V, error 0.1V. Temperature display range -55.0-99.9 Error 0.5 .

Voltage detection range required 0-9.99VHardware error of 0.01V version , please Remarks .

Long press the SET button for three seconds after the release, relay status negated that detects the voltage or temperature exceeds the upper limit of the relay, the detected voltage is lower than the lower limit of the relay releases .

P-3 voltage relay mode:Is "P-1" mode and "P-2" combined mode , the user can control the timer starts by detecting the voltage value.

P-4Thermostat relay mode

Mode Select "P-4", this time into the thermostat relay mode, temperature sensor DS18B20 temperature acquisition environment in real time and through the digital display , temperature range: -55.0~99.9, display accuracy 0.1 , error 1 , the minimum temperature ofExactly the same set of voltage relay modeWhen the temperature is below zero value , the digital point on the last digit indicates the temperature is below zero .

You can set the temperature control of the upper and lower temperature hysteresis as to avoid excessive temperature fluctuation causes the relay to frequent movement .

You can setHeating or cooling modeIf you needTemperature exceeds the upper limitStart relay, orTemperature is below the lower limitStart relay can be switched by pressing the SET button for three seconds and then release action.

P-5 thermostat relay mode

"P-5" mode is "P-1" relay mode with the "P-4" combination thermostat relay mode , when you set the timer operating parameters in the "P-1" mode , enter "P -5 "mode can detect temperature control to start or stop the timer .

P-6 Thermostat voltage relay mode

"P-6" model is "P-2" voltage relay mode and "P-4" combination of temperature control relays , control relays this mode of operation must meet"P-2" voltage relay modeThe setting and the "P-4" Setting the thermostat relay mode .

P-7 thermostat voltage relay mode

"P-7" model is a combination of "P-3" voltage relay and the "P-5" thermostat time relays , control relays this mode of action required to meet timing"P-3" voltage relay modeThe setting and the "P-5" Setting the thermostat relay mode .Can press the ENTER key to toggle the display temperature or voltage value .

P-8Temperature alarm mode

"P-8"Mode and "P-4" temperature relay mode is different, this mode can be set to a temperature in the upper and lower range of the relay is released ( or pull, start the timer ) , when the temperature is higher than the upper limit or below the lower limit , the relay pull, starts a timer ( or release ) , that the temperature exceeds the set range relay, and the next P-4 mode is just above the upper limit of the release ( or pull ) , below the lower limit pull ( or release ) .

If you set the timer time T1 in the P-1 model , the action of the relay will be timed according to the set time to perform in the P-8 mode , if the P-1 under the T1 mode is set to 0 , that is, the timer does not work , the relay will directly pull releases .
