Table 1-5: CP383 Digital Output Specifications
TYPE DESCRIPTION
Output Voltage Range Low state: =< +1.5 V
High state: > +8.0 V and < +35 V
Current per channel: max. 0.5 A
Leakage current: 20 µA
Channels 16 channels grouped into two clusters of eight channels each
Common GND and VCC for each output cluster
The output channels are isolated from the system side and share common
GND and VCC within the clusters. The two output clusters are galvanically iso-
lated from each other.
Channel Connections 1 pin per channel, single-ended
External Reset All digital output channels of a cluster can be collectively switched low by
using one of the following methods:
• externally via the EXTRESET signal
• internally on request from the application via the DIO ProComm
Controller
This results in all outputs being kept switched low irrespective of the input
data for these channels.
External Voltage (VCC) +9.5 V to +35 V
