2) 16-way active switch signal: high level 18V, low level 0V.

5Function:

According to the field service conditions, control state of the output port by setting the input port state.

6 Display:

LCD, realizing various function setting and status indication.

7 Intrinsically safe power output parameters (see Table 1):

The control box mainly consists of the main explosion-proof chamber, human-machine operation LCD touch screen, incoming and outgoing wiring chamber and intrinsically safe chamber. The upper part includes the main chamber and wiring chamber, and the lower part is the intrinsically safe chamber. The main explosion-proof chamber adopts the bolt fastening structure, so as to facilitate equipment installation, commissioning and maintenance. The front of the master control explosion-proof box is installed with PLC module, and there is the power module box at the lower. The front door panel is installed with the operation button and extra-large LCD touch screen, and the operation interface is simple and friendly. The voice module, horn and wiring terminal are installed in the intrinsically safe chamber.
