HI, CAN I USE ONE KC868 COLB TO manage multiple Relay boards. for example :
Am working on a project that needs multiple KC686-H32B Relay assembly.
and i want to use one KC868 COLB to drive up to 2 units of KC686-H16 and i unit of KC686-H32 located at different remote location from each other.

one KC868-COLB only automatic control for one relay controller by RS232 cable connected.

Hi,

COLB don't have 5 v supply as COL. Do I have to provide a 5V supply to sensors.
(Like Humidity sensor)

thanks

yes, use extend power supply for sensor is good for COLB controller, that will stable.
