5pin PCB general purpose relay T91 30A 240VAC, 32.5*27.5*28mm
Description:
A relay is an electrically operated switch. Many relays use an
electromagnet to mechanically operate a switch, but other operating
principles are also used, such as solid-state relays. Relays are
used where it is necessary to control a circuit by a low-power
signal (with complete electrical isolation between control and
controlled circuits), or where several circuits must be controlled
by one signal.
Features:
• Small size, light weight.
• Low coil power consumption, heavy contact load.
• Strong anti-shock and anti-vibration, high reliability, long life.
Applications:
Suitable for automobile, machine, electronic equipment, air
conditioner and household appliances applications. PC board
mounting and direct insert mounting available.

CAUTION:
1.The use of any coil voltage less than the rated coil voltage will
compromise the operation of the relay.
2.Pickup and release voltage are for test purposes only and are not
to be used as design criteria.
3.Unless otherwise stated, the rated coil voltage specified in coil
parameter tableshall be used for all tests and its application to
the relay

Notes:
• We recommend dust protected types for a clean environment (free
from contaminations like H2S, SO2, NO2, dust, etc.).
We suggest to choose plastic sealed types and validate it in real
application for an unclean environmen t(with contaminations like
H2S, SO2, NO2, dust, etc).
lf water cleaning is required after the relay is assembled on PCB,
please contact us for suggestion about suitable parts.
• To avoid using relays under strong magnetic field which will
change the parameters of relays such as pick-up voltage and
drop-out voltage.
• Relays may be damaged because of falling or when shocking
conditions exceed the requirement.
• Regarding the wash tight relay, we should leave it cooling
naturally until below 40°C after welding, then clean it and deal
with coating. remarkably the temperature of solvents should also be
controlled below 40°C. Please avoid cleaning the relay by
ultrasonic, avoid using the solvents like gasoline, Freon, and so
on, which would affect the configuration of relay or influence the
environment.
