ES930.1 - User Guide 97
Sensor Supply
Number of channels 4
Arrangement of channels 2 channels at "AI 1-4" connection and
2 channels at "AI 5-8" connection
Assignment of channels Assignment to sensors or input chan-
nels of the ES930.1 can be randomly
configured
Output voltage Configurable per channel:
predefined values ("Off", +5 V, +8 V,
+10
V, +12 V, +15 V) or
user-defined (+5 V to +15 V, resolution
10
mV)
Output current Max. 50
mA per channel (at 5
V output
voltage)
Max. 30 mA per channel (at 15 V out-
put voltage, all channels loaded simul-
taneously)
Output resistance <0.5 (measured at connector)
Accuracy of output voltage ±(5 mV + V
sensor
* 0.2%) (with 500
load)
Ripple of output voltage V
pp
<30 mV (20 MHz bandwidth)
Max. voltage drift (temperature) ±2 mV/K
Run up time of output voltage 32 ms (all channels simultaneously)
Electrical connection Sensor supply voltage ground con-
nected with supply voltage ground of
module
Maximum voltage 0 V (short circuit) to +26 V DC
Protection Outputs CH(n) and ground
CH(n)_GND protected each with a
fuse against fault-current
Diagnostics Short-circuit detection per channel; if
permissible total output is exceeded,
all channels are switched off
