Omron K8DT-AS Series Monitoring Relay, 20.4-26.4V Supply Voltage, 250ms Time Delay - K8DT-AS1TD
This monitoring relay provides compact, DIN-rail-mounted detection and signalling of current deviations in single-phase systems. It operates from low-voltage AC or DC supplies and responds to both excessive and insufficient current to protect equipment and trigger control logic in automation and electrical installations.
Features and Benefits:
• Detects overcurrent and undercurrent to prevent system faults
• Switches SPST contacts for simple on/off control integration
• Accepts 20.4 to 26.4V AC/DC supply for flexible power options
• Senses currents from 2 mA up to 500 mA for fine resolution
• 250 MS time delay to avoid nuisance trips from transients
• Push-in terminals speed installation and wiring changes
• Switches SPST contacts for simple on/off control integration
• Accepts 20.4 to 26.4V AC/DC supply for flexible power options
• Senses currents from 2 mA up to 500 mA for fine resolution
• 250 MS time delay to avoid nuisance trips from transients
• Push-in terminals speed installation and wiring changes
Applications
• Suitable for motor load monitoring to identify stalled conditions
• Ideal for conveyor systems requiring phase-limited current supervision
• Used with control panels for process automation alarm signalling
• Can be used for monitoring current draw on single-phase pumps
• Suitable for retrofit protection on small machinery in workshops

What Terminal arrangement is provided for quick wiring?
It uses push-in type connections that allow tool-free conductor insertion and secure contact retention for efficient assembly.
What environmental limits should be observed during installation?
The unit is designed to operate between -20°C and 60°C and has IP20 ingress protection, so it requires an enclosed control cabinet in dusty or humid locations.
How does the relay indicate or act when current thresholds are crossed?
A single-pole single-throw contact changes state when measured current falls below or exceeds set limits, enabling external alarms or PLC inputs to respond.
What mounting method is required for panel integration?
The device clips onto a standard DIN rail for straightforward mounting within electrical enclosures.
What electrical phase and power consumption characteristics apply?
It monitors single-phase systems and consumes 1.8 VA during operation.
Note
K8DT-AS allow use in either overcurrent or undercurrent mode.
K8DT-AW allow overcurrent and undercurrent monitoring simultaneously
