ABB DOS810 3BSE078768R1 Digital Output Module

The DOS810 is a Digital Output (24V / 0.6A) Signal Conditioning Module supporting 2-wire devices.

Features and Benefits

• Digital output for 2-wire field devices
• 24 V / 0.6 A current sourcing
• Can be used in hazardous areas
• Field power sourced from the power injection
• Short circuit proof, electronically current limited to 0.6 A
• Built-in inductive load suppression, free-wheeling diode
• Galvanic isolation
• Protected against wrong wiring

Diagnostics

• Loop supervision (open circuit and short circuit)
• Hardware error supervision
• Communication supervision
• Internal power supervision
• Power injection supervision
• OSP (Output Set to Predetermined value)
• Single loop granularity - each SCM handles a single channel
• Supports hot swap
• Mechanical locking slider which turns off field device power and/or output before removal
• Field disconnect function which can galvanically separate the field loop wiring from the SCM during commissioning and maintenance
• All SCMs have electronic current limitation
• Mechanical keying to prevent insertion of wrong module type after commissioning
