It delivers two BFOC ports at 860 nm multimode, supporting redundant ring or daisy-chain topologies over glass fiber. Rated supply is 24 VDC (18.8–28.8 V), drawing 0.2 A max. The module handles PROFIBUS from 9.6 kbps up to 12 Mbps, plus PA subnetwork at 45.45 kbps. Operational ambient range is -25…+60°C horizontally mounted, with IP40 protection. Dimensions are 112 x 39.5 x 74.5 mm (H x W x D). CE marked, complies with EN 61000-6-4 (emissions Class A) and EN 61000-6-6 (immunity). No additional compliance certificates listed in the spec base. Depth of 74.5 mm. PROFIBUS interface uses a 9-pin Sub-D socket. Power and signaling use a 5-pole terminal block; the measuring device uses a separate 2-pole block. Verify polarity on the 24 VDC supply input.","metaTitle":"Siemens 6AG1503-3CB00-2AA0 SIPLUS NET OLM/G12 V4.0, 2x BFOC,","metaDescription":"Active SIPLUS NET OLM/G12 V4.0 with conformal coating, -25...+60°C, 2 BFOC ports, PROFIBUS 9.6 kbps–12 Mbps, 24 VDC, 0.2 A, IP40. 74.5 mm depth.
