Axis Port & Aux Port DC Inputs
Configuration The auxiliary inputs are divided into two groups of six inputs. Each
group can be configured for sourcing or sinking. The axis inputs
have one input per axis. Each input can be configured for sourcing
or sinking.
Operates with IEC Type 1 inputs (per IEC 1131=2).
Input voltage Nominal 24 VDC, maximum 30 VDC
Guaranteed on voltage 15 VDC
Guaranteed off voltage 5 VDC
Turn on/off time 1 ms
Fast inputs 50
μ
sec
Axis Port DC Outputs
Number of outputs 2 outputs per axis
Configuration Each set of axis outputs can be configured as sourcing or sinking.
Maximum current 100 mA per output
Voltage range 24 VDC nominal, 5 to 30 VDC range
Scan loss response Outputs turn off
Aux Port +5 Vdc Output
+5 VDC 150 mA maximum current available. Connections to this point
should be over short distances and away from electric noise signals.
