DO820 Digital Output Module, Relay
Manufacturer: ABB — S800 I/O
Part number: DO820
Category: Electrical
8-channel relay digital output module, individually galvanically isolated, normally open contacts.
Description
The DO820 Digital Output Module has 8 relay output channels with individually galvanically isolated normally open contacts. Each channel provides a dry contact relay output suitable for switching a variety of loads including AC and DC circuits. Output state can be set to a predetermined value (OSP) if a communication error is detected. The individual galvanic isolation makes this module suitable for applications where each output must switch different voltage levels or where isolation between channels is required.
