ماژول خروجی آنالوگ ABB مدل AOS810، کد فنی 3BSE078764R1

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 AOS810 is an Analog Output Signal Conditioning Module (16 bit) supporting 2-wire devices and HART communication.
Features and benefits

Analog output for 2-wire field devices
Signal range: 0…20 mA or 4…20 mA
Can be used in hazardous areas
16 bit D/A converter
Channel to channel galvanic isolation
Configurable output rise/fall times (down to 1 ms; with HART down to 20 ms)Protected against wrong wiring
Diagnostics:

Loop supervision (open circuit and short circuit)
Hardware error supervision
Communication supervision
Internal power supervision

Support of HART field devices (up to HART application layer rev. 7):

HART Pass-Through
Cyclic read of up to two HART Device Variables
HART Device Validation

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
24V DC powered through Modulebus
Configurable through parameters
LED indicators on the SCM indicate the operational state of the module (3BSE078764R1)
