Time relay module 6-30V Micro-USB

Power Supply

Wide‑range DC power supply: 6–30 V DC.

Supports power input via micro USB 5.0 V connector.

The user interface is clear and simple, while the module provides powerful and flexible functions.

Equipped with a one‑touch emergency stop button (STOP key) and reverse‑polarity protection – incorrect power connection will not damage the module.

It is possible to set different OP, CL, and LOP parameters. These parameters are independent of each other and are stored separately.

All configured parameters are automatically saved in non‑volatile memory and are retained after power‑off.

Micro USB Interface

Product Parameters

1. Operating voltage: 6–30 V DC; supports power input from micro USB 5.0 V.
2. Trigger source: high‑level signal 3.0–24 V. The input is equipped with optocoupler isolation, which improves the system’s anti‑interference capability (the common grounds can also be shorted together if required by the user).
3. Output function: the relay can control loads up to 30 V DC / 5 A or 220 V AC / 5 A.
4. Quiescent (static) current: approx. 20 mA; operating current: approx. 50 mA.
5. Service life: more than 100 000 switching operations; operating temperature: –40…+85 °C; dimensions: see manufacturer’s drawings.
6. Optocoupler isolation, enhanced EMC/anti‑interference performance, industrial‑grade PCB.

Special note: The relay output provides passive dry contacts only (a simple switch). The relay does not output its own supply voltage.

TYPE‑C Interface

• Operating voltage: 6–30 V DC.
• Supported supply: TYPE‑C 5.0 V power input.
• Trigger signal source: high‑level trigger 3.0–24 V. The trigger signal ground and system ground are not common by default to improve noise immunity (they can be shorted together by the user if required).
• Output capacity: the relay can control up to 30 V / 5 A DC or 220 V / 5 A AC loads.
• Static current: approx. 20 mA; operating current: approx. 50 mA.
• Service life: more than 100 000 cycles.
• Operating temperature: –40…+85 °C.
• Equipped with optocoupler isolation, enhanced anti‑interference capability, industrial‑grade circuit board, and non‑volatile memory for parameter storage.

Operating Modes

P1: After a trigger signal is received, the relay turns ON for the duration of OP, then turns OFF. During the OP interval, the behavior depends on the sub‑mode:

• P1.1: a new trigger signal during OP is ignored.
• P1.2: a new trigger signal during OP restarts the timing (OP countdown restarts from the beginning).
• P1.3: a new trigger signal during OP resets the timer and turns the relay OFF (timing stops).

P2: When a trigger signal is applied, the relay first remains OFF for the CL delay time. After CL expires, the relay turns ON for the OP time. When the OP time elapses, the relay turns OFF.

P3.1: When a trigger signal is applied, the relay turns ON for OP, then OFF for CL, and this ON/OFF sequence is repeated. If another trigger signal is received during the cycle, the relay turns OFF and the timer stops. The number of cycles (LOP) can be configured.

P3.2: After power‑up, no trigger signal is required. The relay automatically turns ON for OP, then OFF for CL, and repeats this cycle. The number of cycles (LOP) can be configured.

P4: Mode with signal‑holding function:

• While the trigger signal is present, the timer is cleared and the relay remains ON continuously.
• When the trigger signal disappears, the module starts timing OP; when OP elapses, the relay turns OFF.
• If another trigger signal appears during the OP timing, the timer is cleared again, and the relay remains ON.

Notes

1. Follow the wiring diagram provided by the manufacturer, and do not connect the terminals incorrectly.
2. This document describes the product parameters at the time of editing. Specifications are subject to change without prior notice.
3. The relay output is a passive contact (dry contact). It does not provide power; it only switches an external circuit.

Timing Range

The timing range is continuously adjustable from 0.1 s (minimum) to 999 min (maximum).

How to Select the Timing Range

After setting parameter values in the mode‑selection interface, briefly press the STOP key to select the timing range (position of the decimal point):

• X0.0 – single decimal point; timing range 1 s to 999 s.
• X.X0 – decimal point in the tenths position; timing range 0.1 s to 99.9 s.
• X.X.X – all decimal points lit; timing range 1 min to 999 min.

Example: To set OP = 3.2 s, move the decimal point to the tenths position so that the display shows 03.2.

Parameter Description

• OP – relay ON time.
• CL – relay OFF time.
• LOP – number of cycles (1–999). The value "---" means infinite cycles.

These parameters are independent of each other, but all modes share the same OP/CL/LOP values.

For example, if the ON time OP is set to 5 s in P1.1, and the user switches to P1.2 mode, then upon entering the P1.2 parameter menu, OP will still be 5 s (until changed).

On the main interface (display shows "000"), briefly pressing the SET key will cycle through OP (CL, LOP) and the corresponding value XXX.

• If the selected mode has only OP time (e.g. P1.1, P1.2, P1.3), briefly pressing SET will display only OP and its value.
• If the mode uses OP, CL, and LOP (e.g. P3.1, P3.2), briefly pressing SET will sequentially display: OP and its time, CL and its time, LOP and the cycle count.

This allows quick review of all parameters set for the current operating mode.

Parameter Setting Procedure

1. Determine the desired operating mode of the relay.

2. In the main interface (after power‑up, the module briefly shows the current mode, e.g. P1.1 as the default, and then switches to the main display "000"), press and hold the SET key for about 2 seconds to enter the mode‑selection interface. Use the UP and DOWN keys to select the desired mode (P1.1…P4).

3. After selecting the mode (e.g. P3.2), briefly press SET to enter the parameter‑setting interface. The parameter currently being edited (OP ON time, CL OFF time, LOP cycle count – "---" = infinite cycles) will flash. Adjust the value using UP and DOWN:

• short press – change by 1 step;

• long press – fast increase/decrease.

  Once the value is set, briefly press STOP to select the decimal‑point position and corresponding timing range (0.1 s to 999 min). Then briefly press SET to move to the next parameter for the current mode, and repeat the same procedure.

4. After finishing parameter settings for the selected mode, press and hold SET for about 2 seconds. The current mode will flash, and the module will return to the main interface. The parameters are now stored.

Main Interface

• When the relay is idle (not timing / not active), the display shows "000" without a decimal point.
• When the relay is active (timing in progress or relay ON), the display shows a value with a decimal point.

Mode‑Selection Interface

• To enter: press and hold SET.
• To exit and save: press and hold SET again to return to the main interface.

Relay Output Mode (STOP Function)

There are two output states:

1. ON: the relay is allowed to switch according to the configured OP (ON time).
2. OFF: the relay operation is disabled; it remains permanently OFF.

On the main interface, briefly pressing the STOP button toggles between ON and OFF. The current state will blink briefly and then the display returns to the main screen.

This acts as an emergency stop function – with one button press you can immediately enable or disable the relay output.
