ماژول ورودی آنالوگ ABB مدل AIS850، کد فنی 3BSE078770R1

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 AIS850 is an Analog Input Signal Conditioning Module (16bit) for use in intrinsically safe applications (Zone 0) supporting 2-wire devices and HART communications.
Features and benefits

Analog input for 2-wire field devices
Signal range: 4…20 mA and 0…20 mA
Can be used in hazardous areas providing intrinsically safe signals up to Zone 0
Transmitter power current limited to 25 mA
16 bit A/D converter resolution
Channel to channel galvanic isolation
Hardware filter, rise time 1 ms
Software filter configurable through parameters
Diagnostics:

Loop supervision (open circuit and short circuit)
Internal hardware supervision
Communication supervision
Device malfunction low, underrange, overrange and device malfunction high
detection
Internal power supervision

LED indicators:

Status (S)
Primary (P)

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. (3BSE078770R1)
