SMC PTE 30 CH PORTABLE RELAY TRIP TIMER CHRONOMETER *UK STOCK.

This chronometer has been designed as an accessory to our injection instruments to test protective

relays. Its function is to determine one of the most important parameters, the reaction of the delay

time of a protection relay in relation to a trip condition.

Measurement range (Seconds Mode): 00.000 to 99999 seconds

Measurement range (Cycle Mode): 0000.0 to 9999.9 cycles

Measurement range (Seconds Mode): 20.000 to 4000.0 Hz

Function (Start Stop): Time between two events

Function (Pulse): Time of a signal pulse

Function (Frequency): Read the frequency of the input taps

Accuracy: ±0.01% ±1 ms.

Timer start (Direct Events): activation / deactivation of the start monitor.

• Timer start (BUS-PTE Events): By a positive or negative event in the BUS-PTE.
• Timer stop: Selectionable between activation or deactivation of the signal monitor.
• Contact Closure Input: Voltage-open circuit 10.2 V, Current-short circuit 25 mA.
• Voltage input: 5 - 250 Vdc or Vac (Frequency 20 - 4000 Hz, Input Impedance: 19 KΩ)
