Current output (AO-I) mode
Output response to On/Off switching operations of power supply
Without supply voltage
High-impedance output 200 k
Ω at 0 V
During booting routine of the
DC1000
High-impedance analog output. Brief current peaks up to 2 % may
occur when switching on and switching off.
If there are brief interruptions
If the interruption > 100 µs, the AO are briefly switched to high impe-
dance.
Behaviour in STOP mode
±20 mA
Current output: 0 mA
4 mA to 20 mA
Current output: 4 mA
Effect of defective connection
to the output terminals
Withstands any overload down to no-load status, output voltage limited
to ±14…18 V.
Usage of the AI during AO
operation
The current that really flows can be indicated if the analog input is con-
figured as
AI-I
.
The voltage between A+ and A- can be displayed if the analog input is
confi-gured as
AI-U
. A- must be connected to AGND for the sensor to
be monitored.
Readjustment is not required because it is readjusted internally.
