DIS810

Select I/O is an Ethernet networked, single channel granular I/O system for the ABB Ability™ System 800xA automation platform. Select I/O helps decouple project tasks, minimizes the impact of late changes and supports standardization of I/O cabinetry ensuring automation projects are delivered on-time and under budget. A Signal Conditioning Module (SCM) performs the necessary signal conditioning and powering of the connected field device for one I/O channel.

DIS810 a Digital Input 24V Signal Conditioning Module for 2/3/4-wire devices. Sequence of Events (SOE) enabled.

Features and benefits

• Digital input for 2-wire, 3-wire and externally powered 4-wire field devices
• Can be used in hazardous areas
• Field device power output current limited to 30 mA
• Channel to channel galvanic isolation
• Configurable software signal filter 0...100 ms
• Protected against wrong wiring

• Diagnostics:
– Loop supervision (open circuit and short circuit)
– Hardware error supervision
– Communication supervision
– Internal power supervision

• Sequence of Events (SoE)
• DIS810 supports both Normally Open (NO) and Normally Closed (NC) 24 V loops

• 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
• 24V DC powered through Modulebus
• Configurable through parameters
• LED indicators on the SCM indicate the operational state of the module
