(ter11, -12 resp. +, -) in type of protection “Intrinsic Safety” Ex ia IIC resp. Ex ib IIC
only for the connection to a certified intrinsically safe circuit (e.g.
FISCO power supply) with the maximum values according to the
following table:
FISCO power supply
ia/ib for group IIB/IIC FISCO power supply
ia/ib for group IIB/IIC Barrier or power supply
ia/ib for group IIB/IIC

Characteristic line rectangular Trapezoidal linear
Local interface for
communication (LKS)
and programming interface (X5) 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.
