Information About MK21-122EX0-R
The MK21-122EX0-R belongs to Turck’s MK21 series of monitoring relays, engineered for rotational speed supervision in safety-critical environments. It is designed to interface with NAMUR sensors via an intrinsically safe Ex ia input, making it suitable for hazardous area installations. The device evaluates speed conditions and switches relay outputs based on configurable overspeed or underspeed thresholds. Its compact IP20 enclosure and wide supply voltage range allow integration into control panels across various industrial sectors.
Key Features:
- Single-Channel Speed Monitoring: Provides dedicated monitoring for one rotational speed input.
- Overspeed and Underspeed Detection: Detects speed deviations beyond defined thresholds.
- Intrinsically Safe Input: Ex ia NAMUR input supports use in hazardous environments.
- NAMUR Sensor Compatibility: Designed for standardized proximity and speed sensors.
- Dual Relay Outputs: Two SPDT relay outputs for flexible control and signaling.
- Wide Supply Voltage Range: Operates on 20–250 VAC or 20–125 VDC.
- LED Status Indicators: Visual indication of operating state and relay status.
The MK21-122EX0-R delivers the reliability and precision required for rotational speed monitoring and safety-related shutdown applications.
