6 Jumper (Option)
Jumper JP1 und JP2:
Depending on the position of the jumper JP1 for the contact of the relay REL-1, this is
made available as a break or make contact at the terminals T-1 and T-2. Depending on
the position of the jumper JP2 for the contact of the relay REL-2, this is provided as a
break or make contact on the terminals T-6 and T-15.
Der Zugang zu den Jumpern erfolgt über entsprechend gekennzeichnete Ausbrüche auf
der rechten Seite des Hutschienengehäuses.
7 Loop resistance mA Output
Analog output (AA) data for constant current: max. 22 mA at a load ≤ 500 Ω
The maximum load for the analog output is the sum of the forward and return lines and the
input resistance (shunt) of the following module:
R
Load, max
