Product Features

JSDXC2-1700 dynamic relay was used in computer interlocking interface circuit.

At present, the JSDXC2-1700 dynamic relay has ceased to be used on large railways, and is only used in the hump circuit when the user needs it.

 

Features

1. Two-way dynamic control signal relay.

2. The voltage at the coil end of the relay is in a dynamic state with the change of the drive signal of the electronic components.

3. Dynamic pulse signal 24V1Hz, a square wave with a control ratio of 1:1.

4. Improve the reliability of the computer interlocking circuit.

 

Dimensions

The relay socket is installed on the combination frame (cabinet) with bolts, and the relay is inserted into the socket horizontally and fastened with a storage battery.

JXC-1000/7 type relay identification pin numbers 11, 52; JWXC-1700 type relay identification pin numbers 11, 51.

 

Installation Precautions

1. When installing the relay, make sure that the insulation interval between the sockets is intact, the socket hanging spring is intact, and that the socket identification pin is in the correct position and should not be missing.

2. Pay attention to the relative position between the relay and the socket when pl ing in the relay to avoid damage to the relay or socket during pl ing.

3. When repairing or replacing the relay, first remove the national relay spring, and then pull out the relay. Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket.

 

Faults and troubleshooting methods

1. The relay contact has no output

The analysis and elimination methods of the relay contact without output are as follows:

(1) Make sure that the relay and socket should be reliably pl ed in;

(2) Check that the relay should not be mechanically blocked. If foreign matter in the relay blocks the armature, the armature cannot work reliably (forward rotation) or release (reverse rotation), and the contacts cannot be reliably contacted;

(3) Check that there should be no foreign matter between the contacts, there is foreign matter between the contacts, and the contacts cannot be reliably contacted;

(4) Check that the contact resistance of the relay contact should not be too large.

2. The relay does not work or the relay with a pole cannot be reversed in the forward direction

The relay does not work or the relay with a pole cannot be reversed in the forward direction. The analysis and troubleshooting methods are as follows:

(1) Make sure that the relay and socket should be reliably pl ed in;

(2) Check that the input voltage or current of the relay coil should be the rated value or the system circuit adjustment value.

Method: Use a multimeter to check the voltage relay coil input terminal voltage on the socket should meet the output voltage of the power supply screen; use a multimeter to check the voltage drop of the current relay coil input terminal on the socket should meet the voltage drop requirements of the system circuit for reliable operation of the relay; otherwise, system error;

(3) If the above two items are normal, it can be determined that the relay is faulty and the relay should be replaced;

(4) The relay coil is short-circuited or disconnected, the relay cannot work reliably or has a pole relay;

(5) The diode of the rectifier relay is impacted or short-circuited, and the rectifier relay cannot work reliably;

(6) Check that the relay should not be mechanically blocked. If a foreign object in the relay blocks the armature, the relay cannot work reliably or reverse polarity.

3. The relay does not release

The relay non-release analysis and troubleshooting methods are as follows:

(1) Make sure that the relay and socket should be reliably pl ed in;

(2) Check that the input voltage or current of the relay coil should meet the requirements of the system circuit for reliable release of the relay.

Method: Use a multimeter to check that the voltage relay coil input terminal voltage on the socket should be less than the release voltage of the relay; use a multimeter to check that the voltage drop of the current relay coil input terminal on the socket should meet the requirements for reliable release of the relay in the system circuit; otherwise, it is a system failure;

(3) If the above two items are normal, it can be determined that the relay is faulty and the relay should be replaced;

(4) Check that the relay should not be mechanically blocked. If a foreign object in the relay blocks the armature, the relay cannot be reliably released.
