The TT7H 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 voltage: 220 V a.c. 60 Hz; Voltage fluctuation: ±10 % of the power voltage; Power consumption: About 9.6 VA (220 V a.c. 60 Hz); Control output: Contact composition | Output : Instantaneous SPDT (1c).
Additional technical characteristics include Contact capacity: NO contact : 250V a.c. 5 A resistive load, NC contact : 250 V a.c. 2 A resistive load; Output: Instantaneous SPDT (1c).
The physical design of TT7H should be considered together with the installation environment and the available mounting or display arrangement. Noise immunity: Square wave noise due to the noise simulator(pulse width : 1 us), ±2 kV (within operation power terminal); Vibration: Resistance | 10 - 55 Hz (cycle for 1min) Peak amplitude 0.75 mm for 1 hour each in X, Y and Z direction; Shock: Resistance | 300 m/s² 3 times each in X, Y and Z direction; Ambient temperature: -10 ~ 55 ℃ (without icing).
Further construction and environmental details include Storage temperature: -20 ~ 65 ℃ (without icing); Ambient humidity: 35 ~ 85 % RH.
Integration of TT7H begins with matching its connection, input or control signal and output requirements to the surrounding equipment. Input type: Non-voltage input | Impedance when disconnected : Max 1 KΩ, Remaining voltage when disconnected : Max 2 V Impedance when opened: Min 100 KΩ; Power voltage: 220 V a.c. 60 Hz; Display type: ON time display : Red FND 4 digits (character height 18.7mm) OFF time display : Red FND 4 digits (character height 14.5mm); Control output: Contact composition | Output : Instantaneous SPDT (1c).
Additional operating and interface details include External Connection type: Terminal type; ON time display: Red FND 4 digits (character height 18.7mm); OFF time display: Red FND 4 digits (character height 14.5mm). These values provide a practical reference for wiring, setup and normal operation within the selected configuration.
