RT 78 724/725/726 is Schrack's Industrial Power Relay RT series DIN rail socket for RT relays with 3.5mm / 5mm pins, relay height 15.7mm. The socket has a logical connection setup (input/output), a new retainer clip with ejection function, and can be easily replaced on a densely packed DIN rail. It has high-quality rising clamp terminals, captive combination terminal screws, no reduction of protection class or creepage/clearance with plastic retainer, simple plug-in indicator- and protection modules, and white snap-on marking tags.
The Tyco RT series industrial power relays are general‑purpose relays designed for DIN‑rail mounting. The datasheet provides detailed technical parameters, approvals, and accessory information such as retaining clips, marking tags, and LED modules.
Key features include multiple pinning options (3.5 mm and 5 mm), RoHS compliance, IP20 protection, and a wide ambient temperature range. The document also lists compatible socket types for both DIN‑rail and PCB mounting, along with part numbers for each accessory. This manual is written in Chinese.
