Hetai Tech

Hetai Tech JK11S-100S-5V 10A 0-100s Adjustable Delay Timer Relay Module

SKU CH-Y51N-V78WJ

A 5 V DC timer relay module with independently adjustable on and off periods from 0.2 to 100 seconds, 10 A switching capacity and 0.03 s trigger response

  • Adjustable 0-100 second timing range for flexible automation
  • Independent T1 and T2 control via dual potentiometers
  • 10A relay handles high-current loads with NO and NC contacts
  • 03s trigger response ensures precise activation timing
  • Compact 70*20*19mm board fits tight enclosures

Purpose and User

This Hetai Tech timer relay module provides adjustable on-off cycling for 5 V DC circuits. It suits makers, students and engineers building automation experiments, lighting sequences or equipment interlocks where independent timing control is required.

Sustained Behaviour

The module draws 8 mA at rest and 95 mA when the relay is energised, with a 10 A resistive load rating on both normally open and normally closed contacts. Industrial-grade microcontroller timing keeps the cycle stable over long runs, and the 0.03 s trigger response prevents missed edges during continuous operation.

Integration Checklist

Verify your supply delivers 5 V DC and can source at least 95 mA for the coil plus the intended load current. Confirm the 70 mm by 20 mm footprint fits the enclosure and that wiring can reach the trigger terminals, which accept only passive switch contacts — no active voltage signals. Ensure the 0.2 s minimum on-off step meets the resolution your application needs.

Questions about this item

How much heat and power does the module draw when running continuously?

Quiescent current is 8mA and operating current is 95mA at 5V DC, so the module itself adds very little heat or power load during all-day operation.

What must the buyer already have to make the module work?

A 5V DC power source capable of at least 95mA and a passive switch or button to short the trigger terminals are required; the trigger cannot accept an active signal.

Can the 10A relay contacts switch loads on the same older circuits the buyer already uses?

The normally open and normally closed contacts are rated for 10A, so they can control existing loads that stay within that current limit regardless of the load voltage.
