FAQs
What are the different timing modes available on the H3CR-A8?
The H3CR-A8 supports on-delay, flicker-on/off, interval, and one-shot delay modes.
What is the maximum time setting for this timer?
The timer can be set for a maximum duration of 300 hours.
Can this timer be used with both AC and DC power supplies?
Yes, it is compatible with 24-48 VAC or 12-48 VDC input power.
What is the output contact configuration?
It features DPDT (Double Pole Double Throw) contacts, meaning it has two independent sets of changeover contacts.
What is the maximum current rating for the output contacts?
The output contacts are rated for 5A.
Does this timer require a special socket?
Yes, it is an 8-pin plug-in timer and requires a compatible 8-pin socket for installation.
How do I adjust the time setting?
Time settings are adjusted using the rotary switches located on the front of the timer, in conjunction with the selected time range.
Troubleshooting
Timer does not power on
Verify input power supply voltage and connection. Ensure the timer is fully seated in its socket. Check the socket wiring for continuity.
Timer does not switch output at the set time
Confirm the correct timing mode and time value are selected. Check if the input signal is present and valid for the selected mode (e.g., for one-shot delay). Verify the load is within the 5A rating.
Output is constantly ON or OFF
Ensure the correct timing mode is selected. Check for any short circuits in the load wiring. For modes like interval, verify the trigger signal behavior.
Inconsistent timing
Check for voltage fluctuations in the input power supply. Ensure the ambient temperature is within the operating range. Inspect wiring for loose connections.

Setup, Compatibility & Care
Setup:
- Socket Selection: Ensure you have a compatible 8-pin timer socket installed in your control panel.
- Wiring: Connect the input power (24-48 VAC or 12-48 VDC) to the appropriate terminals on the socket, observing polarity for DC.
- Output Wiring: Connect your load circuits to the DPDT output terminals, ensuring the total load does not exceed the 5A rating.
- Mounting: Insert the H3CR-A8 timer into the socket, ensuring it is seated correctly.
- Setting Time and Mode: Use the rotary switches and selectors on the timer's face to set the desired time range, time value, and operating mode.
Compatibility:
- Input Power: Compatible with 24-48 VAC or 12-48 VDC.
- Socket: Requires a standard 8-pin plug-in socket.
- Output Load: Suitable for loads up to 5A at 250 VAC / 30 VDC.
Care:
- Keep the timer clean and free from dust and moisture.
