Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
The Transformer Isolated Driver Type KFD2-(S)CD2-Ex*.LK is a single or two channel device designed to provide galvanic isolation between intrinsically safe apparatus located in a hazardous area and associated apparatus located in a non-hazardous area and limit the voltage and current into the hazardous area to intrinsically safe levels.

The apparatus comprises a number of electrical components, including transformers, fuses, resistors and zener diodes, all mounted on a single printed circuit board and housed within a plastic enclosure.

The use of '*' in the type description may be '1' or '2' for single or two channel respectively.

The use of 'S' in the type description specifies SMART versions; no 'S' signifying non-SMART versions.

The apparatus is designed to operate from a d.c. supply of up to 35V on terminals 7 to 9, terminals 10 to 12 (second channel), terminals 14 and 15 and on power rail connector terminals 1, 2 and 4. The segregation of the hazardous area circuits meets the requirements for 250V.

For electrical data see Additional information.
 
SPECIFIC CONDITIONS OF USE: NO

Additional information:
 
Two Channel Transformer Isolated Driver Type KFD2-(S)CD2-Ex2.LK

Terminals 7 to 12, 14 and 15 and power rail terminals 1, 2 and 4

Um = 250V

Terminals 1 and 2 (Channel 1) and Terminals 4 and 5 (Channel 2)

Uo = 25.2V
Io = 93mA
Po = 585mW

Ci = 0
Li = 0

The capacitance and either the inductance or the inductance to resistance ratio (L/R) of the hazardous area load must not exceed the following values:

Group Capacitance, µF Inductance, mH OR L/R Ratio, µH/ohm
IIC 0.107 3.05 (4.2) 60
IIB 0.82 9.15 (17) 243
IIA 2.9 24.4 (33) 486
I 4.3 26 787

When the external circuit contains no lumped inductance i.e. the Li of any attached apparatus is zero, the cable inductance may be increased to the values within parentheses.

Single Channel Transformer Isolated Driver Type KFD2-(S)CD2-Ex1.LK

Terminals 7 to 9, 14 and 15 and power rail terminals 1, 2 and 4

Um = 250V

Terminals 1 and 2 (Channel 1)

Uo = 25.2V
Io = 93mA
Po = 585mW

Ci = 0
Li = 0

Load parameters are unchanged.
