Features:
- Remote chassis adapter: links SLC 500 I/O to a Universal Remote I/O scanner
- Configurable rack image: supports 2–32 logical groups in two-group steps
- Extended-node capability: participates in the documented 82 Ω network design
1747-ASB gives a remote SLC chassis a defined logical presence on an established RIO link.
Its identity is inseparable from the DIP-switch settings that determine addressing, image size, and recovery behavior.
Selection therefore depends on the scanner plan and installed rack map rather than communication rate alone.
Apter Power can review 1747-ASB Series, switch record, RIO image, official documentation, condition, and quotation requirements.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Starting address: retain the logical rack and group assigned by the scanner
- Image size: reserve only the groups required by the installed chassis
- Specialty I/O: distinguish discrete and block-transfer mapping before changing the addressing mode
- Common rate: configure every scanner and adapter for the same Kbaud value
- Cable limit: match total Belden 9463 length to the selected rate
- Termination plan: use the resistor value required by the complete node population
- Output response: document hold-last-state selection for loss of RIO communication
- Restart lockout: decide whether restored links resume automatically or await operator action
- Status proof: interpret the display and COMM/FAULT LEDs before enabling remote outputs
- Remote SLC I/O chassis: extend discrete and specialty I/O over an installed RIO link
- Legacy plant distribution: retain rack-based communication between a central scanner and remote panels
- Chassis modernization boundary: preserve the logical image while individual remote modules are serviced
