Omron K8AK-AW Series Monitoring Relay, 24V Supply Voltage, 5A Relay Contact Current - K8AK-AW2 24VAC/DC


This monitoring relay provides overcurrent and undercurrent detection for single-phase control systems, used to supervise load current and trigger switching actions within industrial electrical panels. It mounts on DIN rail and connects via screw terminals, intended for installations where adjustable response timing and modest power draw are required.

Features and Benefits:


• Detects currents from 0.1A to 5A for precise load supervision
• Adjustable response time 0.1–30s to prevent nuisance trips
• SPDT contact for versatile control of alarms or breakers
• Rated switching voltage 250VAC for common control circuits
• Power consumption 4.6VA to minimise auxiliary loading
• Conforms to EN60947-5-1, UL and RoHS for standardised interoperability

Applications


• Suitable for motor protection against phase load loss or overloads
• Ideal for control panels monitoring pump current draw
• Used for conveyor systems to detect underload conditions
• Can be used for preventative maintenance alerts in machinery

What supply voltages will operate the unit?


It accepts DC or AC supply with 24VAC/DC and can also be used with a 240V AC supply rating for auxiliary circuits as required.

How is the device mounted and wired in a control cabinet?


It clips onto standard DIN rail and uses screw terminals for secure conductor connections compatible with typical industrial wiring practices.

What environmental limits should I observe during installation?


Operate within a temperature range of -20°C to 60°C and protect from dust and water ingress consistent with an IP20 enclosure rating.

What are the contact current capabilities for switching loads?


The relay contacts are specified for switching currents up to 5A, suitable for control-level loads and signalling circuits.

Standards

EN 60947-5-1 pollution level 2 installation category III, UL 508.
Terminal protection IP20.
