The KG-ID-V4 Inline Driver simplifies operating coil devices, like solenoids and electromagnets, with its hit-and-hold configuration. This driver activates at full power and then drops down to a lower holding power, significantly reducing operating temperature and energy consumption. Different hit-and-hold profiles, including a solid-state relay profile, are available for various coil devices. The driver is easily activated with a logic signal, triggering the driver by connecting the trigger input to ground or sending a logic "0" input to the pulled-up +5v trigger input.
