DX-31B, 31BL, 32A, 32AL, 32B, 32BJ type signal relays

1. Overview
The DX-31B, 32A, and 32B signal relays are suitable for DC operated relay protection circuits, while the DX-31BJ, 32AJ, and 32BJ signal relays are used as action indicators in AC operating systems.

2. Structural characteristics
This relay adopts a JK embedded housing and has two structural types: embedded rear wiring (JK-01K) and protruding rear wiring (JK-01H). Its appearance and installation dimensions are shown in the appendix of this manual. Rf in the wiring diagram of the back terminal is an external voltage reducing resistor for the voltage holding circuit. Before using the relay, it must be connected to the circuit according to the diagram.
The DX-31 relay is a relay with an action indicator button. When the coil is energized, the armature is attracted, the signal button pops up, and the dynamic contact closes at the same time. Manually reset.
DX-32A, J type and DX-32B, J type relays use crystal lights (light-emitting diodes) as signal indicators. When the working coil is powered on, the contacts remain in the working state due to the action of the holding coil. When the coil is powered off, the relay returns to its starting position and the indicator light goes off (white).
