It reads two channels of RS-422 incremental or SSI absolute encoders, with two digital inputs and two digital outputs per channel. The coating and -40 to +70°C temperature rating suit installations in condensation-prone or wide-ambient environments—refrigeration, outdoor cabinets, high-humidity process areas. Standard product, returnable, stocked as A-class. ## Delta vs standard 6ES7551-1AB01-0AB0 The only functional difference from the standard unit is the conformal coating and the wider ambient range. Electrical specs—encoder interface, digital I/O count, backplane power draw—are identical. If the BOM already specifies the standard 6ES7551-1AB01-0AB0 and the environment demands coating or the -40 to +70°C span, this is a drop-in upgrade. No software or configuration changes required. Active with no last-time-buy or successor noted; stocked as standard product, quoted to order; RoHS compliant since 13-09-24, REACH info available.","metaTitle":"Siemens 6AG1551-1AB01-7AB0 SIPLUS TM PosInput, -40..+70°C","metaDescription":"SIPLUS S7-1500 TM PosInput 2 module, conformal coated, -40 to +70°C, 2-channel for RS-422/SSI encoders.
