It supports Modbus serial, DNP3, IEC 60870-5-103, and SPAbus protocols. Schneider discontinued the REL52816 on 2024-12-01. The REL52816 uses fibre optic media (glass 62.5/125 µm) and speaks Modbus serial, DNP3, IEC 60870-5-103, and SPAbus. The REL52820 is an RS485 communication module with direct mounting and an RS232 relay connection — pick the REL52820 when the panel uses copper RS485 wiring rather than fibre.","metaTitle":"Schneider REL52816 PowerLogic P3 fibre optic module, discontinued","metaDescription":"Schneider REL52816 PowerLogic P3 fibre optic communication module, glass receiver/transmitter, 12 V DC via RS232, Modbus/DNP3/IEC 60870-5-103/SPAbus, discontinued 2024-12-01.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Depth":"0.8 in (20 mm)","Width":"2.4 in (62 mm)","Height":"3.4 in (86 mm)","Supply":"12 V DC via external supply via RS232 port","Category":"US1PL1S11405","Connector type":"2 ST 1 SUB-D 19 pins 1 RS232","lifecycle_stage":"current","Range of Product":"Easergy P3 VAMP","Device composition":"Glass transmitter Glass receiver","Operating Distance":"1000 m","Optic Fibre Diameter":"Glass fibre 62.5/125 µm","Nbr. of units in pkg.":"1","Product or Component Type":"Fibre optic module","Communication Port Protocol":"Modbus serial DNP3 IEC 60870-5-103 SPAbus","Accessory / separate part category":"Communication accessory","Maximum number of supported devices":"32"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$639.06","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/206e75cbf7b0ebbb2cd25d2c630f434f.pdf","sourceUrl":"https://www.se.com/ae/en/product/REL52816/communication-module-powerlogic-p3-fibre-optic-with-glass-receiver-and-glass-transmitter/","alternativesUrl":"https://aoctrl.com/api/mcp/products/REL52816/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/REL52816","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/REL52816 when reusing this data.
