Allen Bradley 1771-ASB /D Remote I/O Adapter Module

Allen-Bradley 1771-ASB/D Remote I/O Adapter Module

The Allen-Bradley 1771-ASB/D Remote I/O Adapter Module is a key component in the 1771 Series I/O system, designed to facilitate efficient communication between remote I/O modules and programmable controllers. This module serves as an interface, enabling seamless data transmission and system integration.

Key Features

• Data Transmission: Supports data transmission up to 10,000 cable-feet at 57.6K baud, and up to 2,500 cable-feet at 230.4K baud, ensuring reliable communication over long distances.
• Versatile I/O Support: Accommodates various I/O configurations, including 4, 6, 8, 16, or 32 points, providing flexibility for diverse application requirements.
• Addressing Methods: Offers three I/O addressing methods—1/2-slot, 1-slot, and 2-slot—to optimize system configuration and performance.
• Configuration Verification: Performs I/O configuration checks upon power-up to verify module placement, enhancing system reliability.
• Backplane Scanning: Scans all slots in the chassis or all but the last four slots, allowing improved scan time and I/O image space savings. Slot power supplies can be used in the last quarter of the rack without using I/O space.
• Emulation Capability: Can emulate Series B adapters, providing system response similar to the 1771-ASB Series B, allowing use of 1771-S4A and -S4B scanners which require slower response for proper operation.

Technical Specifications

• Backplane Requirements: 1.0 Amps at 5 VDC
• Dimensions: 2.0″ x 11.0″ x 7.0″ (5.1 cm x 27.9 cm x 17.8 cm)
• Weight: Approximately 1 lb 14.1 oz (0.9 kg)
• Country of Origin: United States

Compatibility

The 1771-ASB/D module is compatible with Allen-Bradley PLC-5 systems and integrates seamlessly with other components in the 1771 Series I/O chassis, ensuring cohesive system performance.
