5.6 Analog output 4 to 20 mA
A safety- related analogue output is available at terminal strip [x5 | ANALOGUE OUT].
The current output is freely scalable by setting parameters “Analog Start” and “Analog
End”.
If the analogue output is not used, [X5:2] and [X5:3] must be bridged. An error is
detected when the analogue output is open (e.g. wire breakage).
In the normal state, the output signal moves in the range between 4 and 20 mA.
In case of an error, the analogue output is controlled by 0 mA.
The connection of the analog output is only safe if the following device can detect the
fault condition of the safety device.
The terminal [X5] provides 9 connections:
[X5 | ANALOG OUT] Analog out [X4:2-3]
[X5 | ENCODER OUT] HTL / RS422-Output [X4:4-9]
Pluggable 9-pole terminal [X5]

If the analogue output is not used, [X5:2] and [X5:3] must be
bridged.
• An error is detected when the analogue output is open (e.g. wire
breakage).
•
In case of an error, the analogue output is controlled by 0 mA.
•
The Safety Integrity Level (SIL) or the Performance Level (PL) is
reduced if only the analog output is connected. A parallel
connection of splitter and relay output or switching output is
necessary to reach SIL3/PLe.
