Wide operating voltage range 5V-30V delayed relay/timer. It is design to

provide  24 sec. delayed output. If longer time delay is required,

one can replace capacitor on board C2 with higher capacitance

calculated with the following formula.

T=1.1RC  R is in Meg. ohm, C is in uf (micro farad)

e.g. R=1M=1,000,000     C=22uf=0.000022

so T=1.1*RC=24.2 sec.

When power is first apply relay output terminals (NO) and (COM)

is opened, only (NC)  and (COM) are in contact. When (TRIG )

input receives a low input signal, the indicator light is on and the

relay output terminals (NO) and (COM) are in contact , (NC)and

(COM) opened for up to 24 seconds depends on the adjustment

of the variable resistor.

Operating Voltage: 5V-30V

Relay Contacts：10A 250VAC（AC），10A 30VDC（DC）

Price: $4.50
