EB3C type relay safety barrier is an intrinsically safe explosion-proof device. Its input contacts can be used in various explosive gases and 0 zone hazardous areas.
This manual describes the IDEC EB3C intrinsic‑safety relay barrier, including its compact design, weight reduction compared with the IBRC series, and compatibility with PLCs. It lists the applicable safety standards (IEC 60079, FM, CSA, CE, ATEX, TIS, CQST) and the various certification classes for different regions.
Installation instructions cover DIN‑rail mounting (35 mm) or direct screw fixation, wiring diagrams for single‑ and multi‑contact configurations, and detailed precautions for use in hazardous zones. Technical data such as voltage, current, power ratings, temperature limits, and terminal assignments are provided in tabular form. This manual is written in Japanese.
