D5072-096
- SIL 2 Thermocouple/mV Repeater
G.M. International ISM0388-4

When used with separately powered intrinsically safe devices, check that maximum allowable voltage, current (Ui/Vmax, Ii/Imax) of the D5072-096 Associated Apparatus are not
exceeded by the safety parameters (Uo/Voc, Io/Isc) of the Intrinsically Safe device, indicated in the table below:
For installations in which both the Ci and Li of the Intrinsically Safe apparatus exceed 1 % of the Co and Lo parameters of the Associated Apparatus (excluding the cable),
then 50 % of Co and Lo parameters are applicable and shall not be exceeded
(50 % of the Co and Lo become the limits which must include the cable such that Ci C cable
≤
50 % of Co and Li L cable
≤
50 % of Lo). The reduced capacitance of the external circuit (including cable) shall not be greater than 1
μ
F for Groups I, IIA, IIB and 600 nF for
Group IIC.
If the cable parameters are unknown, the following value may be used: Capacitance 200 pF per meter (60 pF per foot), Inductance 1 µH per meter (0.20 µH per foot).
