Bachmann ISI222/8 Positioning Module | 8MHz Incremental Encoder Interface

Bachmann ISI222/8 High-Speed Positioning Module for Precision Motion Control

The Bachmann ISI222/8 Positioning Module (Part No. 00014127-00) delivers exceptional performance for demanding motion control applications requiring high-speed incremental encoder feedback. Engineered with dual 8 MHz encoder inputs, 14-bit analog outputs, and advanced synchronization capabilities, this module provides the precision and reliability needed for industrial automation, robotics, and process control systems.

Key Applications & Solutions

This positioning module excels in applications requiring precise position tracking and velocity measurement. Common deployment scenarios include CNC machining centers, automated assembly lines, conveyor positioning systems, and robotic arm control. When integrated with the Bachmann MX213 Processor Module, it forms a complete motion control solution capable of managing complex multi-axis operations.

For applications requiring additional I/O expansion, pair this module with the Bachmann DIO216/4 Digital I/O Module or the Bachmann AIO288/3 Analog I/O Module to create comprehensive control architectures.

Technical Specifications

Advanced Encoder Interface Features

The ISI222/8 supports multiple evaluation modes including 1x, 2x, and 4x edge counting, as well as pulse-direction mode, providing flexibility for various encoder types. The 32-bit counter resolution ensures accurate position tracking even in high-speed applications. Signal inputs include differential A-, A+, B-, B+, N-, N+ channels for robust noise immunity in industrial environments.

Integrated SYNC signal synchronization enables precise coordination with other modules in your Bachmann M1 automation system. Advanced diagnostic features include reference monitoring, cable break detection, and encoder resolution monitoring to ensure system reliability.

High-Performance Analog Output Capability

Two 14-bit analog outputs deliver ±10V signals with exceptional accuracy (0.025% at 25 °C) and fast conversion times under 40 µs. Maximum output current of ±2 mA with settling time under 500 µs makes these outputs ideal for servo drive control and proportional valve applications. Built-in cable break detection and permanent short-circuit protection ensure operational safety.

System Integration & Compatibility

Designed for seamless integration with Bachmann M1 controller systems, the ISI222/8 mounts directly onto BS2xx series backplanes. The module works in conjunction with Bachmann MP213/E Controller Modules and MPC240 PLC/CPU modules for comprehensive motion control solutions.

For power supply requirements, combine with the Bachmann NT255 Power Supply Module to ensure stable 24V DC operation across your entire control system.

Frequently Asked Questions

Q: What is the difference between ISI222/8 and standard ISI222?
A: The ISI222/8 supports higher input frequencies up to 8 MHz compared to 1 MHz on the standard ISI222. However, the ISI222/8 does not support SSI (Synchronous Serial Interface) encoders, while the standard ISI222 does.

Q: Can this module work with absolute encoders?
A: No, the ISI222/8 is designed specifically for incremental encoders with A, B, and N (index) signals. For absolute encoder applications, consider the ABB FEN-11 Absolute Encoder Interface.

Q: What terminal accessories are recommended?
A: We recommend the KZ-ISI222 B terminal set (Part No. 00014277-30) with Phoenix cage clamp connectors and labeling strips for easy installation and maintenance.

Q: Is this module suitable for harsh environments?
A: Yes, with an operating temperature range of -30 °C to +60 °C and marine certifications (ABS, BV, DNV, KR, LR, NK, RINA), it’s designed for demanding industrial and marine applications. For extreme cold environments, consider the ColdClimate version of related modules like the BS206-CC ColdClimate Backplane.

Q: How many encoders can I connect simultaneously?
A: The ISI222/8 supports two independent incremental encoders simultaneously, each with its own 32-bit counter and configurable evaluation mode.
