Optionally the following modules are allowed to be used:
Plug-In module for digital
feedback
(Terminals +51 / -52 resp.
+41 / -42)
Plug-In module for analogue
feedback
(Terminals +31 / -32)

IMPORTANT (NOTE)
• The intrinsically safe circuits are galvanically separated up to a voltage of 60 V. The local
communication interface (LKS) is connected with the signal circuit.
