Detail

Product Parameter


1. Power supply voltage: 5V (HW-280A), 12V (HW-280B)


2. Adopt high current relay AC250V/10A DC300V/10A


3. Relay normally open interface with high load: AC 250V/10A, DC 30V/10A


4. Adopting patch optocoupler isolation, strong driving capability, stable performance, trigger current of 5mA


5. Each module can trigger high or low levels through jumper settings


6. The contact part is independently wired, safe and reliable


Product Introduction


Input interface:


1. DC+: Connect to the positive pole of the power supply


2. DC -: Connect to the negative pole of the power supply


3. IN1-IN4: Depending on the settings of each channel, the corresponding relay can be controlled to close at high or low levels



Relay output terminal:


12 wire interface, all interfaces can be directly wired out


NO1--NO4: The relay is normally open, suspended before closing, and short circuited to COM after closing


COM1--COM4: Relay common terminal


NC1--NC4: The normally closed end of the relay is short circuited to the COM before being pulled in, and suspended after being pulled in



High and low level trigger selection terminal


1. S1-S4 are the high and low level trigger selection for relays 1-4 in sequence


2. When COM is short circuited to LOW, the corresponding relay is triggered at a low level, and when COM is short circuited to HIGH, it is triggered at a high level


Product Hot tip


1. The positive and negative poles of the power input terminal cannot be reversed


2. Relays act as switches, controlling the on/off of load circuits and outputting non electrified signals
