Industrial System Architecture & Functionality
The DO828 (Part No: 3BSE069055R1) is a heavy-duty relay output card built for the S800 I/O framework. It features 16 individually isolated channels capable of handling up to 125V d.c. or 250V a.c. at 2A continuous current. Each channel integrates an optical isolation barrier, relay driver, and EMC suppression to safely drive high-voltage industrial actuators.
Global PLC Spare HUB's Insight & Field Experience
Managing high-inductive loads across distributed control nodes frequently introduces severe back-EMF transients that degrade standard switching hardware. Based on our field installation audits, deploying the DO828 with its complete channel-to-channel isolation eliminates cross-talk and ground fault propagation. Instrument engineers praise the integrated Output Safe State (OSP) function, which drives outputs to a secure pre-configured state upon communication loss.

Expert FAQ & Procurement Guide
Q: What specific ModuleTermination Unit (MTU) is required for physical wiring of the DO828?
A: The module requires the TU851 MTU matching the ED keying code configuration.
Q: How does the Output Safe State (OSP) function protect connected actuators?
A: When a controller communication fault or module error is detected, OSP forces all designated outputs into a safe, pre-programmed default position.
Q: Can each channel switch different external voltage potentials safely?
A: Yes, because all 16 channels are individually isolated from one another, they can switch completely separate AC or DC voltage sources simultaneously.
Q: Procurement Guide: When should I choose a relay output module over standard solid-state outputs?
A: Select this relay module when you need to switch heavy inductive loads, higher voltages up to 250V a.c., or require complete galvanic isolation between separate field loops.
Q: What hazardous location certifications does this unit carry?
A: It holds C1 Div 2 cULus, C1 Zone 2 cULus, and ATEX Zone 2 approvals, making it suitable for explosive gas atmospheres.
