Galvanic isolation rated at 500 V keeps field-side faults from propagating to the backplane. Mounts on standard S7 mounting rail; dimensions 40 x 125 x 120 mm (WxHxD) — fits a 40 mm wide slot in an S7-300 rack. Powered via the backplane bus; no separate supply needed. Dissipates 4 W. IP20 rated, so plan for installation in a clean, enclosed control cabinet. No last-time-buy or phase-out has been announced for this order code.","metaTitle":"Siemens 6GK7343-2AH01-0XA0 AS-Interface Master, 62 slaves, 4","metaDescription":"Siemens 6GK7343-2AH01-0XA0 AS-Interface Master for S7-300/ET 200M.
