Description

Industrial interface for direct industrial use. Module using high-quality relay, normally open interfaces Maximum load: AC 250V / 30A, DC 30V / 30A.
With optocoupler isolation. Fault-tolerant design, even if the control line is broken, the relay will not operate.
2-Groups shows trigger status lights, can accommodate up to five power system. It has four mounting bolts holes for easy installation.
Support microcontroller, sensors, industrial control information independent trigger.
It supports high / low double-level trigger.User selectable relay control level, you can pull is high, it can be low pull; module containing current limiting resistor, positive and negative controls may be used as the power supply, you can also use the microcontroller I / O population control.
Control terminal module: 6-wire interface, all the terminals are the interface, user-friendly connection.
1.DC +: positive external DC power supply (with 5V, 12V and 24V modules to choose from).
2.DC-: external DC power supply negative
3.VREF: optically isolated control terminal reference ground.
If a high-level control: This signal should be connected to the negative power of the user control panel.
If a low-level control: This signal should be connected to the positive power of the user control panel.
CH1: Relay control interface
If VREF negative one: This port is a high level (as opposed to VREF) when the corresponding relay.
If VREF positive power supply: when this port is low (as opposed to VREF) corresponding relay.
Relay outputs: 6-wire interface, all the terminals are the interface, user-friendly connection.
1.NO1-NO2: normally open relay interfaces, relay before hanging, pull back with COM.
2.COM1-COM2: Relay Common Interface.
3.NC1-NC2: normally closed relay interfaces, relay before with COM, pull vacant post.
