24V 16 Channels Relay Control Module Isolated Expansion Module High/Low Level Trigger Board

Description Isolated 16 way relay control module select high level or low level signal trigger only 5mA current can drive the relay with a control ability of 10A the module adopts high quality power relay small package optocoupler high power High voltage triode blue signal indicator grade double sided PCB board comprehensive board layout stable performance can be widely used in various power control occasions Increase the power supply anti reverse connection function the wrong power supply will not damage the module fault tolerant design the control line is broken the relay will not act The module adopts high quality relays normally open interface load AC 250V 10A DC 30V 10A Using high quality small two way isolation optocoupler strong anti interference ability stable performance trigger current only needs 5mA The working voltage ​of the module is 24V 16 modulesThe user can select the control level of the relay which can be high level pull in or low level pull in the module has a built in current limiting resistor which can be directly controlled by the positive and negative poles of the power supply or the I O port control Power indicator 16 way relay status indicator blue The interface design is user friendly all interfaces can be directly connected through the terminal block which is very convenientThere are 4pcs 3mm fixing bolt holes for easy installation Module interface Module control terminal 19 wire interface all interfaces have wiring t
