1734-SSI Description

1734-SSI Key Features

• Single SSI Channel Interface: Equipped with 1 dedicated SSI channel, compatible with any absolute encoder that supports the standard SSI protocol, including linear, rotary, and optical distance-measuring devices, with an RS-422 physical interface for clock and data signals.
• Flexible Data Rate Selection: Supports software-selectable SSI data rates of 125 kHz, 250 kHz, 500 kHz, 1 MHz, and 2 MHz, with a default rate of 125 kHz, allowing adaptation to different cable lengths and application requirements.
• Versatile Data Processing: Capable of handling both gray and binary codes, with built-in gray-to-binary conversion functionality; supports software-selectable SSI bits per word (2–31 bits) and word delay time (16 µs–65535 µs) for flexible data customization.
• Enhanced Control Functions: Features SSI word latching with I1 input, increasing/decreasing SSI count indication, and 2 SSI word comparator values, enabling precise position monitoring and control.
• Modular & Easy Integration: Part of the Allen-Bradley Point I/O system, compatible with 1734-TB and 1734-TBS terminal base units; supports DIN rail mounting via the terminal base, with a compact design for space-efficient installation in control panels.
• Reliable Performance: Built with industrial-grade components, supporting a wide operating temperature range (-20°C to 55°C) and IP20 enclosure rating; features SSI position forming time ≥0.5 ms for stable data acquisition, even in electrically noisy environments.
• Cable Flexibility: Compatible with UL CM/AWM 2464/CSA Type CMG FT4 or similar shielded twisted-pair cables, with cable length dependent on data rate (up to 320 m at 125 kHz, 8 m at 2 MHz) for flexible installation across different industrial setups.

1734-SSI Materials & Applications

Materials

• Housing: Industrial-grade flame-retardant thermoplastic (compliant with flame spread rating 5VA) with a compact, robust structure, ensuring shock and vibration resistance for long-term use in pollution degree 2 industrial environments.
• Internal Components: High-reliability industrial-grade integrated circuits and isolated RS-422 transceivers for stable signal transmission; optional conformal coating (for models with suffix “K”) to resist moisture, dust, and chemical contamination, enhancing durability in harsh conditions.
• Connectors: High-quality terminals compatible with 1734-TB/TBS terminal bases, with a maximum screw torque of 0.6 Nm (7 lb-in); RS-422 interfaces for clock and data signals ensure corrosion resistance and reliable connectivity.

1734-SSI Typical Applications

• Motion Control Systems: Providing absolute position feedback for servo motors in factory automation, including conveyor systems, assembly lines, and packaging machinery, enabling precise speed and position control.
• High-Precision Positioning: Used with linear and rotary SSI encoders in applications requiring accurate measurement, such as machine tools, robotics, and optical distance-measuring systems.
• Distributed I/O Integration: Building distributed I/O systems for machine control, connecting encoders to Logix controllers in petrochemical, water treatment, and metallurgical industries, ensuring seamless data exchange between field devices and control systems.
• Industrial Automation: Suitable for harsh industrial environments, including Class I, Division 2, Groups A-D hazardous locations (when properly marked), supporting reliable operation in temperature ranges from -20°C to 55°C.
