Environmental Specifications
The Pulse Generator device with Programmable Delays, model DG-3O1I-17 is designed to work
indoors, according to the following ranges.
•
Temperature Range: 10 ° C - 40 ° C
•
Maximum Relative Humidity: 80% without condensation and temperature above 31 ° C.
•
External Power Supply: 8VDC -12VDC, 2.5W.
•
Power Supply from USB bus: 5VDC, 2.5W with electrical isolation
Feature of Secure USB by Electrical
The equipment, to which the DG-3O1I-17 device is commonly connected, can work with
potentials and high voltage signals (~ 10kV), for example laser equipment with active optical
switches. Such potentials can, due to installation error or loss of insulation, find a way to low
voltage (~ 5V) control lines damaging sensitive equipment. Therefore, the DG-3O1I-17 has a
SECURE USB for your computer equipment; for being designed according to industrial techniques
and components that provide electrical insulation according to standards.
•
UL: 2500 V rms for 1 minute, conforming to UL 1577
•
CSA # 5A Component Acceptance Notice
o
IEC 60950-1: 600 V rms
•
VDE Certificate of Conformity
o
DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 VIORM = 560 V peak
Therefore, high voltage pulses that may be applied by mistake to the input or outputs of the
DG-3O1I-17, will not be transmitted to the computer equipment or to the external power supply.
The protection is in both directions, that is, some damage to the computer or transitory
equipment in the power line, nor will it be passed to the DG-3O1I-17 output lines..

If the equipment is powered from the USB bus only, note that the output levels will drop to
approximately 4VDC. If the equipment to be synchronized accepts these levels, there is no problem,
otherwise, to obtain TTL output levels of 5VDC nominal, use alone or together with the USB the external
power supply provided with the equipment.
