Product Details

The AB 1771-ASB is a PLC 5 Universal Remote I/O Adapter Module. It interfaces with I/O modules in a 1771 I/O chassis with a Remote I/O scanner port for a processor over an I/O link. Using it instead of direct wiring reduces startup, installation, and maintenance costs by the I/O being closer to the actuators and sensors. It is compatible with 32 I/O-adapter devices via the I/O link and it uses 82 Ohm or 150 Ohm terminating resistor.

The 1771-ASB module has a communication rate of 57.6 Kbps, 115 Kbps, and 230 Kbps and it weighs 1.9 pounds. It has a backplane current load of 1 A at 5 Volts DC and a maximum power dissipation of 5.2W. It requires a remote I/O adapter port for connection. For installation, it must be mounted in the left-most slot of the 1771 chassis with the I/O modules controlled by a PLC 5 processor. For wiring, the 1770-CD Belden 9463 or equivalent cable must be used. The 1771-ASB module has Active, Adapter Fault, and I/O Rack fault diagnostic Indicators, 2 switch assemblies, and a field wiring arm. It provides faster data transmission and backplane scanning up to 2500 feet at 230.4K Baud. It supports serial communication and reads/writes data in parallel form. It supports 4, 8, 12, 16, or 32-slot I/O chassis and 1 and 2-slot I/O addressing. The 1771-ASB improves scan time and I/O image space savings by scanning all slots except the last 4. It eases troubleshooting with its enhanced diagnostics features.
