Apparatus
Parameters
The Intrinsically Safe Apparatus Parameters are defined as follows.
Parameter Description
Vmax Maximum safe voltage which can be applied to the apparatus
terminals.
Imax Maximum safe current which can be applied to the apparatus
terminals.
Ci Unprotected capacitance in the apparatus which can be considered
present at the terminals.
Li Unprotected inductance in the apparatus which can be considered
present at the terminals.
The Associated Apparatus Parameters are defined as follows
.
Parameter Description
Voc Maximum output voltage which can be delivered to the hazardous
(classified) location. This voltage is the maximum from a single
channel.
Isc Maximum output current which can be delivered to the hazardous
(classified) location. This current is the maximum from a single
channel.
*Vt Maximum output voltage which can be delivered to the hazardous
(classified) location. This voltage is the maximum across any
combination of terminals of a multiple channel configuration.
*It Maximum output current which can be delivered to the hazardous
(classified) location. This current is the maximum through any
combination of terminals of a multiple channel configuration.
Ca Maximum capacitance which can be connected to the apparatus.
La Maximum inductance which can be connected to the apparatus.
*CSA does not recognize these parameters at this time.
