ماژول ورودی دیجیتال ABB مدل DIS810، کد فنی 3BSE078766R1

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.
The DIS810 is a Digital Input 24V Signal Conditioning Module supporting 2/3/4-wire devices with Sequence of Events (SOE).
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 (3BSE078766R1)
