What is AS-i?

• Actuator Sensor interface (AS-i) is a simple wire
  reduction system
• Easily replaces point to point wiring and
  complements existing higher level bus systems
• Reduces wiring and eliminates multiple
  termination points
• Connects inputs and outputs via a single two wire
  flat cable
• Easy to install and commission

AS-i vs. Point-to-Point Wiring
4
Point-To-Point Wiring

• Each bit of data needs its own wire.
• Power is run separately (more wires).
• Additional I/O points require additional PLC I/O
  cards.
• Additional PLC I/O cards may require the use of a
  larger PLC rack or multiple racks.

5
Less Material Labor

• Smaller PLC rack.
• Smaller enclosures.
• Less wire.
• Standardized patch cables.
• Potential to eliminate J-boxes.
• Simpler documentation.
• Less commissioning time.

6
Simple Installation Expansion

• One cable for many bits of data.
• One master replaces many PLC I/O cards less
  wiring.
• Quick disconnect at modules vs. point-to-point
  terminations.
• I/O modules connect easily to the bus via
  insulation displacement connectors (IDC).

7
Simple Installation Expansion

• Modules connect easily to the bus via insulation
  displacement connections (IDC).
• Mechanically coded flat cable - AS-i and
  additional power supply
• Insulation displacement connectors - simple
  safe - protection class up to IP67, - cables
  reseals up to IP65

Easier Troubleshooting

• Less wire means less opportunity for error, less
  places to look for errors.
• Communication errors are captured by the master.
• Indicating lights on modules and masters
  communicate system and module status.

15
Control Integration

• Two methods to connect AS-i to your existing
  platform
• Method 1 Direct PLC connection
• Fits into standard card slot in a PLC rack
• Replaces traditional I/O cards
• I/O are mapped directly to I/O tables
• Programmed and configured through standard PLC
  software

• Available for most PLC platforms

16
Control Integration

• Two methods to connect AS-i to your existing
  platform
• Method 2 Complements current fieldbus
  networks
• Gateway becomes a single node on the fieldbus
  network, up to 992 I/O points per gateway
• Reduces the price per point for connecting
  sensors and actuators
• Available for DeviceNet, Profibus, Ethernet /IP,
  Modbus TCP, and CanOpen

AS-i power supply

• After selecting the platform, pick an AS-i power
  supply
• An integral and required part of an AS-i system
• Specialty 30 VDC power supply use to couple the
  master data for transmission over the AS-i cable
• 2.8, 4 and 8 Amp versions available
• Provides power to all input devices and modules
  on the system
