Description
A preheating relay belongs to the field of excavator technology.
The preheating relay technically comprises a single-chip
microcomputer, a current sensor, a relay body and two amplifiers,
wherein one end of a normally-open contact of the relay body is
connected with the anode of a power supply, the other end of the
normally-open contact of the relay body is connected with a
preheating plug of a diesel car via the current sensor, output
signals of the current sensor are amplified by the second amplifier
and then connected to a pin 13 of the single-chip microcomputer, a
pin 12 of the single-chip microcomputer is connected with a control
coil of the relay body via the first amplifier, fault signals
output by a pin 8 of the single-chip microcomputer are connected
with an input port of an engine ECU, and a pin 10 of the
single-chip microcomputer is connected with the control signal
output end of the engine ECU. According to the utility model, a
fault monitoring and protecting circuit composed of the single-chip
microcomputer and the current sensor is added to a traditional
preheating relay.
Characteristic
1.Safe and environmental protection, strong and durable
2.long term availability (no obsolescence)
3.easy maintenance
4.fail safe control system which is cyber secure and insensitive to
electro magnetic
5.Relays are ideal to use in excavator for signal transfer/repeat,
safety interlocking functions (brake - doors), load on-off
switching and sub-system isolation.
