For the connection to a programmer resp. a PC outside of the
explosive hazardous area.
Optionally the following modules are allowed to be used:
Shutdown-switch-input
(ter51, -52
resp. +85, -86)
in type of protection “Intrinsic Safety”
Ex ia IIC resp. Ex ib IIC
only for the connection to a certified intrinsically safe circuit with the
following maximum values:
U
i
= 30 V
effective internal capacitance:
C
i
= 3.7 nF
The effective internal inductance is negligibly small.
Mechanical digital feedback
(terminals 51, -52
resp. 41, -42)
in type of protection “Intrinsic Safety”
Ex ib IIC
Maximum values see IEC Certificate No.
(proximity switches of the company P Fuchs GmbH)
The intrinsically safe circuits themselves are safe galvanically separated up to a voltage of 60 V. The
“Local interface for communication (LKS) and programming interface (X5)” is connected with the signal
circuit.
