RM16HLE Double-Isolated 16 Channel Relay Board 5V 12V 24V Low/High Level Optional
Introduction:
The double-isolated 16-channel relay control module,using of high-level or low-level voltage signals trigger,only 3mA current to drive the 10A load relay. And using of high-quality power relay,Ultra-small SMD package optocoupler, high-withstand voltage transistor,red & blue signal lights,double-sided PCB board,layout considerations accurate and stable performance,widely used in various types of power control occasions.
Features:
1.Using of high-quality relay,Normally open relay contacts maximum load:AC 0--250V/10A,DC 0--30V/10A;
2.Using of high-withstand voltage transistor, strong driving ability, stable performance, trigger current of 3mA;
3.There have 5v, 12v, 24v three operating voltage modules to choose from; also have 1, 2, 4, 8,12 channel modules to choose from;
4.User can select the relay control level ,it can be high-level pull or low-level pull; the module contain limited flow resistance, Trigger signal can be DC power supply positive or negative, also can be microcontroller I/O port set ;
5.Fault-tolerant design, if the control line is broken, the relay will not operate;
6.The power indicator (red LED), 2-channel relay status indicator(blue LED);
7.The interface humanization design, all interfaces can be drawn through terminals connect directly, very convenient;
8.The module size: 15.2cm (L) * 10.0cm (W) * 2.0cm (H);
9.Which has four fixed bolt holes for easy installation.
Relay Module Interface
The module control terminal:
15-wire interface, all interfaces have terminal blocks, very convenient.
1.DC+/VCC: The positive electrode of the DC power (there is 5V, 12V and 24V modules to choose from)
2.DC-/GND: The negative electrode of the DC power
3.VREF: optically isolated control terminal the reference power supply
If the high level control: This signal should be connected to the negative terminal of the power supply in the user control panel
If the low-level control: This signal should be connected to the positive power supply in the user control panel
4.CH1-CH2:Relay control interface
If VREF tied to the negative power supply: This port is high level (relative to VREF) corresponding relay pull;
If VREF tied to the positive power supply: This port is low level(relative to VREF) corresponding relay pull;
The relay module outputs:
36-wire interface, all interfaces have terminal blocks, very convenient.
1.NO1-NO12: the relay normally open contacts;
2.COM1-COM12: the Relay common contact;
3.NC1-NC12: the relay normally closed contacts.
Note: Isolated relay module is designed to adapt to the electromagnetic environment is relatively poor , if you want to achieve full isolation, the user control panel power (the connection VERF reference power) and the power supply of relay module (DC + / DC-) should be distinguished. If these two power supply of land, that can’t reach the completely isolated effects, then the user can choose a more economical standard relay module from us.
