Description
Impulse Sealer Timer Circuit Board (PCB Relay Module)
Used In: Hand-operated impulse sealers (heat-sealing machines)
Primary Function:
Controls the sealing time duration for the heating element by powering the transformer that energizes the nichrome wire for a set time interval. Ensures consistent seals on plastic bags.
Product Description (as if for listing or identification):
Manual Impulse Sealer Timer PCB Relay Module
-
Type: Timer Circuit Board Assembly
-
Application: For Hand/Manual Impulse Sealing Machines
-
Compatible With: Single Transformer systems
-
Function: Controls the heat timing of the sealing wire based on the user-set timer
-
Components Typically Included:
-
Timer potentiometer (adjustable knob)
-
Relay switch
-
Indicator LED
-
Buzzer (sometimes)
-
Connectors for transformer, heater element, and AC input
-
-
Voltage: Usually 220V or 110V (check based on region)
-
Relay Rating: Typically 10A 250V AC
⚙️ What it Does:
This PCB controls the heat cycle of the impulse sealer. When the sealing arm is pressed down:
-
The circuit activates the transformer.
-
The heating wire receives power for the set amount of time.
-
The relay switches off after the timer runs out.
This enables consistent sealing for plastic bags or pouches.
-
