D5014
- SIL 3 Repeater Power Supply
G.M. International ISM0103-3
When used with separate powered intrinsically safe devices, check that maximum allowable voltage, current (Ui/Vmax, Ii/Imax) of the D5014 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).
If the cable parameters are unknown, the following value may be used: Capacitance 180pF per meter (60pF per foot), Inductance 0.60µH per meter (0.20µH per foot).
