Technical Data
Signal outputs
Monitor output:
4 … 20 mA signal, apparent ohmic resistance > 600
S
Correction inputs:
2, adjustable to 0 … 20 or 4 …20 mA
channel and effect adjustable via parameters
Digital outputs via
relay module R 16
(Contact material AgCdO, designed for 230 V AC switching voltage)
___________________________________________________________________
NOTE:
Only passive or non-reactive units may be connected to the outputs of
the R 0016 relay module. Any infeed of 230 V into the unit via terminals
82 - 92 in the event of a fault must be prevented.

230 V supply
All consumers connected to the R 16 relay module are supplied via this
terminal 81
terminal.
It is to have fuse protection provided by the customer in the form of a
max. 16A delayed action fuse.
