RM1HLERelay Control Module Description
Bidirectional Isolated1Relay control module canaccording toUser needs canselectHighorLOWTo control the relay. Genuine high-power relay module the industry's top ultra-small package optocouplers power high-voltage transistor red blue signal lights military-grade double-sided PCB board cloth board consider a comprehensive stable performance it can be widely used in various power control types of occasions.
A Module Description
1 the module uses genuine quality relay normally open interfaces Maximum load: AC 250V / 10A DC 30V / 10A;
2 the use ofThe industry's top quality ultra-compact optocoupler Anti-interference ability stable performance; the trigger current is only 3mA;
3 the module voltage 5V 12V 24V to choose from; another one-way 2-way 4-way 8-way modules to choose from;
4 the relay pull high the module containing the current limiting resistor the high level can be DC + can also single-chip I / O port is set high;
5 fault-tolerant design even if the control line is broken the relay will not operate;
6 power indicator (red)1Relay status indicator (blue)
7 interface design user-friendly all interfaces are available through the wiring terminal direct connection leads very convenient
8 module size:2.7cm *5.0m * 1.8cm (L * W * H)
9 with 4 fixing bolt holes for easy installation
Two module interface
Module control terminal:
Have4Line interface all interfacesThere TerminalsUser-friendlywiring
1 DC +: external DC power supply negative (with 5V 12V and 24V modules to choose from)
2 DC-: external DC power supply negative
3 VERF: optically isolated control terminal reference to ground this signal should be connected to the negative power of the user control panel
4 CH1: relay control interface high (relative to VERF) corresponding relay
Note: Isolated relay module is designed to adapt to the environment is bad or electromagnetic signals require relatively high occasions if you want to achieve complete isolation the user control panel power supply (ie connected VERF reference power supply) power supply and relay modules (DC + / DC-) should be distinguished if these two power altogether the effect is not completely isolated then the user can choose the standard of our more economicalNon-IsolatedRelay module.

1 NO: normally open relay interfaces relay before hanging pull back and COM short-circuited
2 COM: Relay Common Interface
3 NC: normally closed relay interfaces relay and COM short-circuited before after the pull-vacant
Four: Frequently Asked Questions
1.How to select relay module power
Each module hasVCCandGNDTwo interfaces the two interfaces are connected to the power supply power supply number of volts depending on how much you choose volt relay if you choose5VRelays use5VPower supply the same token if you choose12VRelays use12VPower supply because the power is supplied to the relay control coil. The control circuit can withstand the highest60VVoltage but the relay coil not so in strict accordance with the requirements of the selection power relay.
2.Relays long closed and normally open interfaces how to understand
Each relay has three output interface NO COM NC It is used to control large electrical current off COMIs common when the relay off (that is when the relay is not energized).COMEnds withNCConnected together andNOIs not connected the relay is closed the situation is just turnCOMversusNOConnected together andNCThe connection is disconnected.
3.onledLights what role
The red led is the power indicator as long as the correct power-up redledOn the light blueledCorresponding to the specific relay there are several relays on the module there are several blueledAnd so on the corresponding relay is closed blueLEDTurn on the light.
