Table 7. RTD Terminals Entity Parameters

Uo = 30Vdc

Io = 19 mAdc

Po = 140 mW

The capacitance and either the Inductance or the Inductance to Resistance Ratio (L/R) of the load connected to the 4-pin connector must not exceed the following values:

Group	Capacitance (￿F)	Inductance (mH)	or L/R Ratio
			￿H/Ohm
IIC	0.066	96	247
IIB	0.56	365	633
IIA	1.82	696	633

NOTE

1.The external circuit contains no combined lumped inductance and capacitance greater than 1% of the above values.

Or 2. The inductance and capacitance are distributed as in a cable.

Or 3. The external circuit contains only lumped inductance or only lumped capacitance in combination with a cable.

In all other situations e.g. combined lumped inductance and capacitance, up to 50% of each of L and C values is allowed.

Conditions of Certification (X):

When fitted with the transient option, the apparatus is not capable of withstanding the 500V electrical strength test as defined in Clause 6.3.12 of IEC 60079-11. This must be taken into account during installation.
