Notes for Safe Use of the Certified Product
Intrinsically Safe
DVC6000f digital valve controllers (designated as
controller hereafter) have been proved to be in
conformity with the requirements specified in the
national standards GB3836.1-2000 and
GB3836.4-2000 through inspections conducted by
National Supervision and Inspection Centre for
Explosion Protection and Safety of Instrumentation
(NEPSI). The Ex marking for the products is Ex ia II
CT6/T5/T4, and their Ex certificate number is
GYJ06280. When using the product, the user should
pay attention to the items stated below:
1. The correlation of approved DVC6000f digital valve
controllers in specific product type, Ex marking and
operating ambient temperature this time is as follows:

2. The enclosure of the controller provides a
grounding terminal, and the user should install a
reliable grounding wire connected to it when mounting
and using the controller.
3. The values for intrinsically safe parameters and
maximum internal equivalent parameters of the
controller are as follow:
Max Input
Voltage
Ui (V)
Max Input
Current
Ii (mA)
Max Input
Power
Pi (W)
Max Internal
Equivalent Parameter
Ci (nF) Li (mH)
24 226 1.4 5 0
17.5 380 5.32 5 0
4. As a main unit of a separate design product, the
values for intrinsically safe output parameters of
DVC6005f are as follows:
Max Output
Voltage
Uo (V)
Max Output
Current
Io (mA)
Max Output

Po (mW)
Max Equivalent
Parameter allowed

8.6 2.3 5 8.2 100
5. While the controller forms an intrinsically safe
explosion protection system together with an
associated equipment, the following requirements
must be met: Uo

Li + Lc.
Note
Where Cc and Lc represent distributing
capacitance and inductance of the
connecting cable respectively.
6. The connection cable between the product and
associated equipment should be a cable with
insulation screen and sheath. The screen should be
connected to the ground.
