T21 is a Hanyoung NUX counter / timer for counting events and controlling time-based operations. Its model configuration determines the input method, timing or counting range, display and output functions, with model information of AC | T21 - 1 / 3 / 6 / 3H - 4A10. Power supply voltage: AC | 100 - 120 V a.c. 50/60 Hz; Power supply voltage: A10 | 100 - 120 V a.c.; Control output: Output mode | Power on delay, Interval, Flicker OFF Start, Flicker ON Start.
The operating range, signal conditions, display format, computation speed and connection method should be checked against the machine sequence before installation. Weight: Approx. 42 g; Insulation resistance: 100 MΩ min (at 500 V d.c., Between current-carrying terminals and exposed noncurrent - carrying metal parts.); Dielectric strength: 2000 V a.c. 50/60 Hz 1 minute (Between current-carrying terminals and exposed noncurrent-carrying metal parts.); Noise immunity: ±2 kV (Between power terminal, pulse width ±1 ㎲, square wave noise by noise simulator).
Key strengths of the T21 come from the combination of its functional configuration and practical installation specifications. The following characteristics highlight the values that matter most when comparing the product with equipment requirements.
Power supply voltage: AC | 100 - 120 V a.c. 50/60 Hz; Control output: Output mode | Power on delay, Interval, Flicker OFF Start, Flicker ON Start; Power supply voltage: A10 | 100 - 120 V a.c..
The T21 technical characteristics define the supported input conditions, counting or timing range, display resolution, computation speed and output behaviour. These values determine how the unit responds to machine signals. Power supply voltage: AC | 100 - 120 V a.c. 50/60 Hz; Control output: Output mode | Power on delay, Interval, Flicker OFF Start, Flicker ON Start; Power supply voltage: A10 | 100 - 120 V a.c..
Additional technical characteristics include .
The physical design of T21 should be considered together with the installation environment and the available mounting or display arrangement. Vibration resistance: 10 - 55 Hz (For 1 min), Double amplitude 0.75mm, X·Y·Z each direction for 1 hour; Shock resistance: 300 m/s² X·Y·Z each direction for 3 times; Ambient temperature: -10 ~ 50 ℃ (Without condensation); Storage temperature: -25 ~ 65 ℃ (Without condensation).
Further construction and environmental details include Ambient humidity: 35 ~ 85 % RH.
Integration of T21 begins with matching its connection, input or control signal and output requirements to the surrounding equipment. Power supply voltage: AC | 100 - 120 V a.c. 50/60 Hz; Control output: Output mode | Power on delay, Interval, Flicker OFF Start, Flicker ON Start; Power supply voltage: A10 | 100 - 120 V a.c..
Additional operating and interface details include . These values provide a practical reference for wiring, setup and normal operation within the selected configuration.
Choose T21 by confirming the exact model or configuration against the required operating conditions. The available model information is AC | T21 - 1 / 3 / 6 / 3H - 4A10. Model: AC | T21 - 1 / 3 / 6 / 3H - 4A10; Model: Code | Description; Power supply voltage: AC | 100 - 120 V a.c. 50/60 Hz; Control output: Output mode | Power on delay, Interval, Flicker OFF Start, Flicker ON Start.
Before installation, confirm Power supply voltage: A10 | 100 - 120 V a.c.. Matching the model, electrical ratings, signal requirements, physical arrangement and environmental limits helps keep the product within its specified operating conditions.
