16 Channel Relay Control Module with Two Way Isolation for Interference, Reverse Function, and Excellent Quality Relay (DC12V)

Description

• Isolation : Our 16-channel relay board features two-way isolation for maximum -interference, ensuring stable and operation in electromagnetic environments.
• -Reverse Protection: This relay module includes a -reverse function, damage to module even if supply is connected incorrectly.
• Excellent Quality- Components: We use only genuine, Excellent Quality- relays with a normally open interface load capacity of AC 250V/10A, DC 30V/10A, ensuring durability and performance.
• Flexible Control Options: Users can select control Tier of relay, choosing between -Tier or low-Tier pull-in, depending on their specific needs.
• to Use and Install: module comes with a 19-wire control terminal and a 48-wire relay output terminal, all equipped with wiring terminals for convenient user wiring.

Item Type: Relay Board
Module Control Terminal: 19-Wire interface, all interfaces have wiring terminals, which is convenient for users to wire
1. DC+: External DC Power Supply Positive (5V, 12V and 24V Modules Available)
2. DC-: External DC Power Supply Negative
3. XM: Common Terminal of Photoelectric Isolation Chip
If high level control is adopted: this signal should be connected to the negative pole of the power supply of the user control board
If low level control is used: this signal should be connected to the positive pole of the user control board power supply
4. X1-X16: Relay Control Interface,
If XM is connected to the negative pole of the power supply: when this port is high (relative to XM), the corresponding relay is closed
If XM is connected to the positive pole of the power supply: when this port is low (relative to XM), the corresponding relay is closed
Relay Output Terminal: 48-Wire interface, all interfaces have wiring terminals, which is convenient for users to connect
1. NO1--NO16: The relay normally open interface, the relay is suspended before being closed, and it is short-connected to COM after being closed.
2. COM1--COM16: Relay Common Interface
3. NC1--NC16: Normally closed interface of the relay, the relay is short-connected with COM before the pull-in, and it is suspended after the pull-in.

Package List
1 x Module
Note:
The isolated relay module is to adapt to the severe electromagnetic environment or high signal requirements. If you want to achieve a complete isolation effect, the power supply of the user control panel (that is, the reference power supply connected to XM) and the power supply of the relay module (DC+ /DC) should be distinguished.
