The 5V 16-Channel Relay Module is a convenient board which can be used to control high voltage, high current load such as motor, solenoid valves, lamps and AC load. It is designed to interface with microcontroller such as Arduino, PIC and etc. The relays terminal (COM, NO and NC) is being brought out with screw terminal. It also comes with LED to indicate the status of relay.
The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A, With optocoupler isolation, strong drive capability, stable performance; trigger current of 15 - 25mA;
Module working voltage: DC 5V
Each channel of the module can be triggered by a jumper to set a high level or a low level;
Fault-tolerant design, even if the control line is disconnected, the relay will not move;
With status indicator: power (green), 16-channel relay status indicator (red)
All module size interfaces can be directly connected through the terminal block, which is convenient and practical.
Module interface:
1. DC+: Connect to the positive of the power supply.
2. DC-: Connect the negative of the power supply.
3. IN1-IN8: According to the setting of each channel, the corresponding relay can be controlled by high or low level.
Relay output:
1, NO1--NO16: Relay normally open interface.
2, COM1--COM16 relay common interface
3. NC1--NC16: Relay normally closed interface.
Specification:
- Digital output controllable
- Compatible with any 5V microcontroller such as Arduino.
- Rated through-current: 10A (NO) 5A (NC)
- Control signal: TTL level
- Max. switching voltage 250VAC/30VDC
- Max. switching current 10A
