DC 24V 1-Channel 30A Relay Control Module Bi-Directional Isolated Control Module High Low Level Trigger (DC 24V, 30A 1-Channel)

Size: DC 24V |
Color: 30A 1-Channel1, The module uses high-quality relay, normally open interface
Maximum load: AC 250V / 30A, DC 30V / 30A; 2, The use of ultra-small optocoupler, anti-interference ability, stable performance; trigger current only 3mA; 3, The module operating voltage 5V, 12V, 24V to choose from; 4, The relay high-level pull, the module contains current limiting resistor, high level can be DC +, can also be single-chip I / O port set high; 5, Fault-tolerant design, even if the control line is broken, the relay will not work; 6, Power indicator (red), 1-Channel relay status indicator (blue); 7, All interfaces can be directly connected through the terminal leads, very convenient 8, Module
size: 6.0 cm * 3.0 m * 2.5 cm (L * W * H); 9, With 4 * 2.0MM diameter fixed bolt holes, easy to install; Module interface
Module control: 4 interfaces, all interfaces have terminals, user-friendly wiring; 1, DC
+: External DC power supply negative (5V, 12V and 24V modules available) 2, DC-: external DC power supply negative; 3, VERF: photoelectric isolation control terminal reference ground, this signal should be connected to the user control panel power supply negative; 4, CH1: relay control interface, high level (relative to VERF) corresponding relay pull.
Note: the isolated relay module in order to adapt to the electromagnetic environment is relatively poor or relatively high signal requirements of the occasion, if you want to achieve a complete isolation effect, the user control panel power supply (that is connected to the VERF reference power) and the relay module power supply (DC + / DC-) should be separated, if the two power supply shared ground, then the effect is not fully isolated, then the user can use the standard relay module.
Package Included: 1*DC 24V 1-Channel 30A Relay Module
