The module receives and sends data from and to the I\/O scanner in serial form, and reads and writes data from and to input and output modules in parallel form. It transmits data up to 10,000 cable-feet at 57.6K baud and provides backplane scanning and data transmission up to 2,500 cable-feet at 230.4K baud. The adapter supports any mix of 4, 6, 8, 16, or 32-point I\/O modules and accommodates 1\/2-slot, 1-slot, and 2-slot I\/O addressing methods. It performs I\/O configuration checks on power-up to verify module placement and scans all slots in the chassis or all but the last four slots. Additionally, it can emulate Series B adapters to provide system response compatible with 1771-S4A and 1771-S4B scanners.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransmits data up to 10,000 cable-feet at 57.6K baud and up to 2,500 cable-feet at 230.4K baud.\u003c\/li\u003e\n\u003cli\u003eSupports 1\/2-slot, 1-slot, and 2-slot I\/O addressing modes.\u003c\/li\u003e\n\u003cli\u003eSupports 4, 6, 8, 16, or 32-point discrete and block-transfer I\/O modules.\u003c\/li\u003e\n\u003cli\u003eEmulates Series B adapter link response for compatibility with PLC-2 and PLC-3 scanners.\u003c\/li\u003e\n\u003cli\u003eVerifies I\/O module placement on power-up.\u003c\/li\u003e\n\u003cli\u003eFeatures front-panel ACTIVE, ADAPTER FAULT, and I\/O RACK FAULT LED diagnostic indicators.\u003c\/li\u003e\n\u003cli\u003eIncludes backplane noise immunity retry options selectable via switch assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRemote I\/O chassis interfacing in Allen-Bradley PLC-2, PLC-3, and PLC-5 programmable controller systems.\u003c\/li\u003e\n\u003cli\u003eDistributed industrial control architectures utilizing Universal I\/O chassis.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCatalog Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1771-ASB Series E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModule Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRemote I\/O Adapter Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBackplane Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.0A at 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransmission Distance \/ Baud Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10,000 cable-feet at 57.6K baud;
