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.
