5.8.
Analog-Output 4 to 20 mA
One safety-related analog output
is available at the screw terminal [X4]. The current output is freely
). It delivers an output signal, which is proportional to one of the input
/ Parameter 003) and independent from the connected sensor types. In
case of an unused analog output [X4:2] and [X4:3] must be linked. An open analog output (e.g. wire
fracture) will release an error status.
During normal operation, the output moves in a proportional range from 4 to 20 mA.
In case of errors, the analog output is 0 mA.
The connection to the Analog-Output is only safe if the following device is capable to detect the
error state of the safety unit. In case of errors the operator is responsible to ensure safety conditions
to all system-parts and -components which are influenced by the analog output.
In DS230 / DS240 versions, the screw terminal [X4] is provided with 7 connections:
[X4 | ANALOG OUT] analog output
[X4:1-3]
[X4 | RS422 OUT]
RS422 output
[X4:4-7]
pluggable 7-pin screw terminal [X4] at DS230/DS240
In DS236 / DS246 versions, the screw terminal [X4] has only 3 connections:
[X4 | ANALOG OUT] analog output
[X4:1-3]
[X4 | RS422 OUT]
not available!
pluggable 3-pin screw terminal [X4] at DS236/DS246
In case of an unused analog output [X4:2] and [X4:3] must be linked.
An open analog output (e.g. wire fracture) will release an error status.
