METZ CONNECT Monitor de velocidad DRIW-E16 24V AC/DC 22,5mm 1101501322

The DRIW-E16 from METZ CONNECT stands out as a dedicated speed and frequency monitoring relay, offering precise supervision of rotational speeds and pulse frequencies in industrial automation. Unlike general-purpose monitoring relays, it accepts a wide range of sensor inputs including NPN/PNP, potential-free contacts, and NAMUR sensors, making it adaptable to diverse machine setups.

Highlights

• Monitors speed and frequency from 0.05 Hz to 10 kHz
• Selectable sensor input: NPN/PNP, potential-free contact, or NAMUR
• Adjustable upper/lower frequency limits, hysteresis (0.5% to 50%), and start-up delay (0.1 s to 10 s)
• 1 changeover contact (SPDT) rated up to 250 V AC / 5 A resistive load
• Compact 22.5 mm DIN rail housing with screw terminals
• LED indicators for operating voltage, input signal, and relay status

In daily use

Configure the DRIW-E16 via its front-panel adjustments to match your application's speed thresholds. The relay continuously compares the input frequency against the set limits and switches its output contact when the speed falls outside the acceptable range. The adjustable hysteresis prevents chatter near the threshold, while the start-up delay allows machinery to reach normal speed before monitoring begins. Clear LED indicators provide immediate status feedback for quick diagnostics.
