RM1HLE Double-isolation 1 Single-channel Relay Control Module High/Low Level 5/12/24V Optional

Introduction:

Isolated 1-channel relay control module, the use of genuine high-quality power relays, high-power high-voltage transistors, red, blue signal lights, military grade double-sided PCB board, cloth board to consider a comprehensive, stable performance, can be widely used in a variety of power control the types of 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. Working voltage 5V/12V/24V(for options, please note the voltage you need when you place an order)
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 high or low;
5. Fault-tolerant design, if the control line is broken, the relay will not operate;
6. The power indicator (red LED), 1-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: 5.0cm (L) * 2.7cm (W) * 2.0cm (H);
9. With four fixed bolt holes for easy installation.

Module interface

The module control terminal(4-wire interface with terminal blocks, very convenient)
1. DC+/VCC: The positive electrode of the DC power
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: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(24-wire interface with terminal blocks, very convenient)
1. NO: the relay normally open contacts;
2. COM: the Relay common contact;
3. NC: 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.
