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.
