Question 1

Does this product meet csa or ul standards?

Accepted Answer

Regarding Canada case. Article 2.024 of Canadian Electrical Code states that electrical equipment shall be approved, but lets local jurisdiction make the determination of which approvals are good.

For Quebec code, the super-seeding Article 2.024 lists a number of acceptable certifications and also allows exclusions for electrical equipment of less than 100VA and less than 30VDC, with certain limits regarding lighting, heating and other types of applications.

For Ontario code, the super-seeding Article 2.024 lists a number of acceptable certifications and also allows exclusions for electrical equipments powered by (on the load side of) 100VA or less Class 2 power supply with a voltage below 42V, with again certain limits regarding lighting, heating and other types of applications.

Therefore, the Ontario code is more restrictive that Quebec's code in that matter. As a general rule, when faced with using some CE European or non-CSA certified instruments in a project, using a 100VA Class 2 24VDC Power Source is a good rule to stay within the bounds of the electrical code Country-wide in Canada.

Still, the manufacturer of the equipment has to ensure proper electrical design so as not cause fire or other hazards. In the end, the equipment manufacturer (or the distributor of the equipment, or ultimately the importer of the equipment) is liable for its proper and safe design.

Question 2

How do i wire a led light with this relay?  no trigger needed.

Accepted Answer

Operation Mode:
P1: After triggering signal, switch is connected for "OP" time, then disconnected; within the "OP" time:
P1.1: if trigger signal again, it is invalid.
P1.2: if trigger signal again, restart timing.
P1.3: if trigger signal again, switch is disconnected, stop timing.
P-2: After triggering signal, switch is disconnected for "CL" time, then switch is connected for "OP" time, and disconnect after timing.
P3.1: After triggering signal, switch is connected for "OP" time, then switch is disconnected for "CL" time, and enter loop. If trigger signal during loop, switch is disconnected and stop timing. The loop times (LOP) can be set.
P3.2: After power on, no need trigger signal, switch will be connected for "OP" time, then disconnected for "CL" time, and enter loop. The loop times (LOP) can be set
P-4: Signal holding function. If there is trigger signal, timing will be reset, switch remains connected; when the signal disappears, it will disconnect after "OP" time. During timing, if there is a signal, timing will be reset.
OP: Connect time. CL: Disconnect time. LOP: Loop times(1~999, "---" indicates infinite times)
All above parameters are independent from each other, but all modes use the same parameters. For example, if set OP time as 5 seconds in P1.1, then change to P1.2, then the OP time in P1.2 will also be 5 seconds.
Press SET button at the main interface (display 000), it will show OP(CL, LOP) and corresponding time.
If there is only OP mode (e.g. P1.1,          P1.2, P1.3), press SET button to display OP and corresponding time only.
If there are OP, CL, LOP modes (e.g.P3.1, P3.2), press SET button to display OP, CL, LOP and corresponding time.
After setting mode, press SET button at the main interface to check the parameter of present mode.
How to Choose Timing Range:
After setting parameter in the interface selection mode, press the STOP button to select the time range:
XXX.  If the last decimal point lights up, the time range is 1sec to 999sec.
XX.X  If the second last decimal point lights up, the time range is 0.1sec to 99.9sec.
X.X.X.  If all decimal points light up, the time range is is 1 min to 999 min.
For example, if you set OP as 3.2 seconds, the make the second last point light up, and it displays 03.2
How to Set Parameter:
1. Make sure operation mode.
2. According to the operation mode, at main interface(after power on, it will flash present mode then enter main interface), press and hold SET button for 2 seconds to enter mode selection interface, then press UP, DOWN button to choose mode (P1.1~P-4)
3. After selecting mode, press short SET button to set the corresponding parameter, then the parameter you want to set will flash. Press UP, DOWN button to set value, then press STOP button to select time range. Press SET button to set next parameter.
4. After setting mode parameter, press and hold the SET button for 2 seconds then the present mode will flash, and go back to the main interface.
Main interface: when relay does not work, it shows "000" (no decimal point); when relay is working, it shows decimal point
Mode Selection Interface: Press and hold SET button to enter. After setting, press and hold SET button to back to main interface.

Question 3

can this timer run while a switch is pressed and stop when the switch is released?

Accepted Answer

Hello, it has one key emergency stop function (STOP key). With reverse connection protection, reverse connection does not burn. Thanks for your question.
