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
