Usage
This series of signal relays, including DX-31B,DX-32A and DX-32B, are suitable for dc operation protection lines and serve as action indicators, dX-31BJ,DX-32AJ and DX-32BJ are suitable for AC operation protection lines and serve as action indicators.
Structure and principle
This relay is a clapped-type electromagnetic signal relay, which has an attractive coil (current or voltage) on a "U" type magnetic body and a moving plate on the magnetic body. The insulating plate on the moving plate moves two groups of moving contact points.Dx-31b is an escapement mechanism with mechanical contact latching and equipped with a restriction plate on the moving plate and a signal indicator on multiple nameplates.The DX-32A model has an additional holding coil as a voltage blocking mechanism with a signal lamp on the nameplate.Dx-32b has one more set of moving-closing contacts. The holding coil is in parallel with the signal lamp, and the holding coil can still work normally when the signal lamp burns out.
When the suction coil of dX-31B signal relay is electrified, electromagnetic suction will be generated to pull the moving plate together.At this time, the contact is in a working state (dynamic closing contact is closed). At the same time, the signal plate is placed vertically with the producer to display the action. When the suction coil is cut off, the contact and indicator are still in a working state due to the effect of the restriction plate.When the indicator is pressed, the moving plate returns to the starting position, the limiting plate captures the indicator and the contact returns to the original position.
DX - 32A, DX - 32B type signal relay attracted coil electricity, electromagnetic suction, inhale plate, the contact is in working status, one group of points to keep the coil electricity, indicator, show the actions, when attracting coil power relay by keep the coil electromagnetic suction, remain in working state, when keep the coil power, relay is returned to the starting position.
The relay has two mounting modes: embedded and protruding. Please indicate when ordering
