Description

Features

●

Auto-shut off output once time-out

Button to ON/OFF/RESET timer

Available timer with high precision same as AC

50/60hz

Universal timer is a mixed signal CMOS IC

designed for a fixed timer to drive external RELAY to

implement safety power control. It is applied to

120V/240V and 50/60Hz AC power supply. It can

automatically shut-off load in order to prevent undesired

conditions from the system. Internal timer can present

several kinds of different time: 15mins, 30mins, 45mins,

1hr, 1.5hrs, 2hrs, 4hrs and 8hrs, which is decided by part

number.

●

Build-in RC oscillator

Drive external RELAY

Support 50/60Hz by part

Quick Test Mode (QTM) for manufacturer

Available timer of 15/30/45/60/90/120/240/480min

Buzzer function(PT8A2524/25/34/35/44/45

Optional)
