1sna631151r2700 – (int) buni 20
TE Connectivity / Entrelec 1SNA631151R2700 BUNI-20 is a 16-channel universal interface with a 20-pole Omniconnect connection, pluggable screw-clamp terminals and a maximum operating voltage of 250 V AC/DC for industrial automation wiring.
Why Choose the TE Connectivity / Entrelec 1SNA631151R2700 BUNI-20 Universal Interface?
The TE Connectivity / Entrelec 1SNA631151R2700 is a professional BUNI-20 universal interface module designed to simplify multi-channel wiring in industrial control panels and automation systems. Part of the established Entrelec Interfast MS range, the BUNI-20 provides a structured interface between field wiring and automation equipment using a 20-pole Omniconnect connection and screw-clamp terminals.
Designed as a 16-channel universal interface without LED indication, the BUNI-20 helps reduce conventional point-to-point wiring while improving organisation inside electrical cabinets. Its terminal block assembly incorporates removable comb-type jumper bars, allowing common connections to be configured or individual channels to be separated according to the requirements of the control system.
The 1SNA631151R2700 supports a maximum operating voltage of 250 V AC/DC, a maximum current of 2 A per point and up to 5 A in common conductors. DIN rail mounting and pluggable screw-clamp connectivity make it a practical solution for machine builders, panel builders and automation engineers requiring reliable, serviceable multi-channel connections.
