It accepts any absolute encoder that supports standard SSI, including linear, rotary, and optical distance measuring devices, making it suitable for precise position feedback in automation systems. The module supports a configurable SSI data rate from 125 kHz up to 2 MHz (software selectable), configurable SSI word length of 4 bytes (32 bits) with 2 to 31 bits per word, and a programmable word delay from 16 µs to 64 ms; it also offers Gray or binary coding with optional Gray-to-binary conversion and includes features such as SSI count indication, two SSI word comparator values, and SSI word latching with the I1 input. In addition to the data word, the SSIM23 provides a dedicated Control output word, enabling synchronization and control of the SSI transaction within ArmorPoint networks. For cabling, it specifies shielded twisted-pair connections using UL CM\/AWM 2464\/CSA Type CMG FT4 or equivalent cables to carry the D+\/- and C+\/- signals. This makes the 1738-SSIM23 a robust solution for integrating high-accuracy SSI encoders into Rockwell Automation’s ArmorPoint I\/O ecosystem in motion, robotics, and precision measurement applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658994057518,"sku":null,"price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a9565e59-6b6b-4468-9e77-c3496fcf8bb5.jpg?v=1769526375","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1739-ssim23-armorpoint-input-output-ssi-encoder","provider":"PLG Automation ","version":"1.0","type":"link"}
