• Relay Contact Input/Transstor Input Specfcatons
Input signal:
• Voltage-free contact: Contact closed at 200 Ω or less and
contact open at 100 kΩ or greater
• Open collector: 0.5 V or less (30 mADC) when turned ON,
leakage current of 0.25 mA or less when turned OFF
Dielectric strength:
500 VDC for one minute between input terminals and the
ground terminal
Note
To reduce noise, use a shielded cable for the wiring of the remote control input terminals.
Connect the shield to the ground terminal of the recorder.
