The K8DT-AS2CD from Omron stands as an efficient solution for current monitoring in electrical installations. Designed to function with a power supply voltage of 24 VAC or DC, this relay weighs approximately 2.99 lbs and is compact enough for a variety of mounting locations. It can receive input either directly or via current transformers (CT) within the range of 0.1 to 1 Amp, as well as 0.5 to 5 Amps AC or DC.
This device operates effectively with input frequencies designated for DC or AC sources, operating between 45 and 65 Hz. Users can determine the operating value within a range of 10% to 100% of the total capacity, and it incorporates a reset value that can be adjusted from 5% to 50% of the selected operating value. For resets, the unit offers a manual or automatic reset option depending on user preferences.
The device also provides settings for operating time ranging from 0.1 seconds to 30 seconds, alongside a startup lock time that can be set anywhere from 0 to 30 seconds. Regarding outputs, the relay features an SPDT relay output and an NPN transistor output. The relay output can manage ratings of up to 250 VAC at 5 Amps or 30 VDC at 5 Amps under resistive loads. The transistor output allows for up to 24 Volts DC (with a peak at 26.4 Volts DC) and a maximum current rating of 50 mA.
Furthermore, the relay is rated for an insulation voltage of 600 VAC, ensuring reliable isolation and safety in varied electrical environments. The K8DT-AS2CD monitoring relay is a versatile tool suitable for a range of applications, facilitating effective current management with its adaptable settings.
