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 AIS830 is an Analog Input Signal Conditioning Module for temperature measurements via RTD/TC/mV.
Features and Benefits
Analog input for 2-wire, 3-wire, or 4-wire RTD input or TC input with cold Junction Compensation
Can be used in hazardous areas
16 bit A/D converter resolution
Channel to channel galvanic isolation
Software filter configurable through parameters
Protected against wrong wiring
Configurable software filter
Diagnostics:
Loop supervision (open circuit and short circuit)
Communication supervision
Internal power supervision
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.
