The Monland brand is only authorized to sell Monland branded goods. Buying goods from Monland gives you a great shopping experience. OPE: relay closing time point, CLE: relay off time point
Time period: PE-1 ~ PE-5 5 time periods (OPE to CLE is a time period)
P-1: The relay closes or outputs pulses every day to the OPE time point, and the relay turns off or outputs pulses to the CLE time point.
P-2: set the day, to the OPE time point when the relay closed or output pulse, to the CLE time point when the relay disconnect / or output pulse
P-3: set the date of the month, to the OPE time point when the relay closed or output pulse, to the CLE time point when the relay is off or output pulse
P-4: Set the date 1 to date 2, start every day at the OPE time point, end to the CLE time point, relay action or output pulse
P-5: As with P-4, only the month can not be set

Introduction:
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a
vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.
This frequency is commonly used to keep track of time, to provide a stable clock signal for
digital integrated circuits.

GT-24 Digital wireless Module 2.4G NRF24L01 PA LNA Industrial 1100M Distance
Model : GT-24
The GT-24 module is a 2.4GHz, 100mW, high speed (up to 2Mbps airspeed), high stability, industrial
grade wireless transceiver integrated data transmission module.
The module comes with a high-performance PCB antenna, precise impedance matching, and the
nRF24L01P RF chip, which has higher reliability, more power levels, and longer transmission
distance and lower power than the nRF24L01.
Also built-in RFX2401 power amplifier chip, built-in LNA, receiving sensitivity increased by 10dBm,
working in the ISM band of 2.4GHz~2.5GHz.
The module has sufficient transmit power, good spectral characteristics, small harmonics,
small channel crosstalk, and ultra-small size. It is a model of all Murata raw materials and
industrial grade standards.
It has a standard spacing of 2.54mm in-line interface and 1.27mm patch interface, which is
convenient for users to use with various circuits.
The GT--24 module also comes with a built-in PCB antenna and an ipx carrier external antenna,
which greatly enhances the module's free characteristics and gives the user the greatest freedom.

Rare earth neodymium magnets, also known as NdFeB magnets or neo magnets, are made of a
neodymium alloy, iron and boron.
They have an excellent magnetic property and are extremely strong for their small size.
Neodymium magnets are permanent and have maximum magnetic energy.
Due to the high performance ratio over price, neodymium magnets have become very popular in almost all applications
that require high-performance magnets, such as motors, sensors, computers, communications, medical equipment,
meters, appliances, craft models , jewelry, etc.
our neodymium magnets Sintered neodymium magnets are available in a variety of shapes and sizes, including disc,
cylinder, block, hub, ring, sphere, countersunk.
