AIS810 ABB Ability™ System 800xA® hardware selector

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.rnA Signal Conditioning Module (SCM) performs the

necessary signal conditioning and powering of the connected field

device for one I/O channel.

The AIS810 is an Analog Input Signal Conditioning Module (16-bit)

supporting 2/4-wire devices and HART communications.

Features and benefits

• Analog input for 2-wire or external powered 4-wire field devices

• Signal range: 4...20 mA and 0...20 mA

• Can be used in hazardous areas

• Transmitter power current limited to 30 mA

• 16 bit A/D converter resolution

• Channel to channel galvanic isolation

• Hardware filter, rise time 1ms

• Software filter configurable through parameters

• Protected against wrong wiring

• Configurable software filter

• Diagnostics:

– Loop supervision (open circuit and short circuit)

– Hardware error supervision

– Communication supervision

– Device malfunction low, under range, over range and device malfunction high detection

– Internal power supervision

• Support of HART field devices (up to HART application layer revision7):

– HART Pass-Through

– Cyclic read of up to two HART Device Variables

– HART Device Validation

• 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.
