2.1 CHECKING BEFORE INSTALLATION

Check the list of devices before installation:

2.2 Interface Description

Wide voltage power input can be 12-24V. When wiring the 485 signal line, pay attention that the two A / B lines cannot be reversed, and the addresses between multiple devices on the bus cannot conflict.

The power interface is wide voltage power input 12-24V. For analog products, pay attention to the positive and negative signal lines. Do not reverse the positive / negative current / voltage signal lines.

We provide default cable length of 0.6 meters, you can extend the cable yourself according to your needs.

2.3 Installation Description

The explosion-proof sensor is wall-mounted and can be fixed by three 8mm fixing holes. Customers can use expansion screws or bolts. The size and position of the fixing hole are as follows:
