WMK-4 type and WMK-20 type non-contact pulse controllers are divided into gate positions from 1 to 30. The voltages are 24V, 30V, 36V, 90V, 110V and 220V respectively. They adopt advanced CMOS digital integrated circuits. , SCR output, reliable performance, easy debugging and easy maintenance.

1. Overview of contactless pulse controller

WMK-4 type and WMK-20 type non-contact pulse controllers are divided into gate positions from 1 to 30. The voltages are 24V, 30V, 36V, 90V, 110V and 220V respectively. They adopt advanced CMOS digital integrated circuits. , SCR output, reliable performance, easy debugging and easy maintenance.

JMK-10 and WMK-20 non-contact pulse controllers (devices) are designed with digital setting circuits (i.e. the 10-door output of the 10-type machine can be set arbitrarily. The 20-door output of the 20-type machine can be set arbitrarily) . When in use, the required number of gates can be selected within the range of the entire output gate number range. The display of the two machines uses LED common cathode digital tubes, which is beautiful and clear.

2. Main technical indicators of non-contact pulse controller

5. Output voltage: 24V 36V 110V 220V

6.Complete machine power consumption: ≤40W

7. Overall dimensions: 100×200×300mm

8. Weight: about 3kg

3. Use of non-contact pulse controller

1. Insert the rectangular plug with the output line into the jack at the rear of the chassis. One end of the output line is connected to one end of the solenoid valve. The other end of the solenoid valve is connected to the common line. The common line is generally arranged at the back, and the wires are The color is red.

2. Insert the power plug into the 220V AC power supply.

3. Turn on the power switch and the indicator light should be on.

4. Adjust the pulse interval and pulse width knobs until appropriate.

4. Maintenance and precautions for non-contact pulse controller

1. Welding and poor contact are strictly prohibited in the joints. The output line of a single machine can only be used by a single machine and must not be connected to each other.

2. The replacement fuse cannot exceed 2A, and it is strictly forbidden to use wires or other conductive objects to replace the fuse.

3. The solenoid valve and connecting wires should not be short-circuited or leaked. Always check that the resistance to ground is greater than 2 megohms.

4. When connecting the solenoid valve or troubleshooting the instrument, please turn off the power to avoid accidents.
