16 Channel Relay Module Two Way Isolated Type Optocoupler 16 Channel Relay Module Interface Board High/Low Level DC 5/12/24V 3 Types Optional(DC12V)

CAN SELECT CONTROL LEVEL -- Users can select the control level of the relay, which can be high level pull-in or low level pull-in. With reasonable layout and can be widely used in a variety pf pulverized coal control.
USER FRIENDLY INTERFACE -- User-friendly interface design, all interfaces can be directly connected by the wiring terminals, very convenient. Designed with 4 3mm fixed bolt holes for easy mounting.

Isolation Type 16 Channel Relay Module can select high-level or low-level signal triggering, and only needs 5mA current to drive the relay with 10A control capability to pull in.
The module adopts genuine high-quality power relay, high-quality small-sized package optocoupler, high-power high dielectric strength triode, red and blue signal indicator, military-grade double-sided PCB board, and with reasonable layout and stable performance, can be widely used in a variety pf powers control.

3.
XM: Common terminal of optoelectronic isolation chip
If use high level control: This interface should be connected to the negative pole of control board power supply.
If use low level control: This interface should be connected to the positive pole of control board power supply.
4.
X1-X16: Relay control interface
Relay output interfaces have 48 wiring terminals.
1.
NO1-NO16: Normally open interfaces of the relays
2,
COM1-COM16: Common interface of the relays
3.
NC1-NC16: Normally closed interfaces of the relays
Features:

1. With power supply reverse connection function to prevent damaging the module.

2. The module uses genuine high-quality relay, rated load of normally open interface: AC 250V/10A, DC 30V/10A.

3. Using small-sized two-way isolated optocoupler, with strong anti-interference ability and stable performance; trigger current is only 5mA.

4. Users can select the control level of the relay, which can be high level pull-in or low level pull-in.

5. The module has built-in finite current resistor. The positive and negative pole control of the power supply can be used directly, or use the I/O port of the single-chip to control.

6. Power indicator (red), relay status indicator (blue)

7. User-friendly interface design, all interfaces can be directly connected by the wiring terminals, very convenient.

8. Designed with 4 3mm fixed bolt holes for easy mounting.
