  • MM2XP 2-pole 24VDC Digital Power Intermediate Relay

    MM2XP 2-pole 24VDC Digital Power Intermediate Relay

    MM2XP Intermediate relays are usually used to transmit signals and control multiple circuits at the same time. They can also be used to directly control small capacity motors or other electrical actuators. The structure and working principle of intermediate relay are basically the same as that of AC contactor. The main difference between intermediate relay and AC contactor is that there are more contacts and small contact capacity. When selecting the intermediate relay, the voltage level and the number of contacts are mainly considered.
    In fact, the intermediate relay is also a voltage relay. The difference from the ordinary voltage relay is that the intermediate relay has many contacts, and the current allowed to flow through the contacts is large, which can disconnect and connect the circuit with large current.

  • ZB2-BE101C handle selector push button Option switch

    ZB2-BE101C handle selector push button Option switch

    ZB2-BE101C push button switch, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally reset automatically. Buttons are usually used to issue start or stop commands in circuits to control the on and off of electrical coil currents such as electromagnetic starters, contactors, and relays.

  • Selector 2-position Option switch ZB2BD2C

    Selector 2-position Option switch ZB2BD2C

    The Selector 2-position Option switch ZB2BD2C, also known as a knob switch, combines the functions of the selector and switch contacts, and is a switching device that can turn on or off small currents (generally not exceeding 10A), similar to the working principle of a button switch. Selection switches, like button switches, travel switches, and other switches, are all master electrical appliances that can connect and disconnect control circuits, or send control signals to automatic control systems such as PLCs.

  • GJCF-15 APH Gap Control system Signal Transmitter

    GJCF-15 APH Gap Control system Signal Transmitter

    GJCF-15 APH Gap Control system Signal Transmitter and the Gap Sensor Probe GJCT-15-E are used together to process the signal measured by the probe, and after a comprehensive judgment, an execution command is issued to start the power circuit, so that the sealed sector plate rises, falls or Emergency lift to the upper limit position. It is suitable for detecting the displacement of the air preheater rotor in motion under high temperature and harsh environment.

    GJCF-15 APH Gap Control system Signal Transmitter is used in the seal clearance control system of air preheater. The key problem of the system is the measurement of preheater deformation. The difficulty is that the deformed preheater rotor is moving, and the temperature in the air preheater is close to 400 ℃, and there are a lot of coal ash and corrosive gas in it. In such a harsh environment, it is very difficult to detect the displacement of moving objects.
