PR3 Series of Octal Relays and Bases
The 38 mm wide relay base family PR3 is a modular system, consisting of PR3 relay bases, rugged electro-mechanical DPDT or 3 PDT octal relays( REL-OR ... )as well as a range of practical accessories. Including: pluggable input protection and indication modules, wiring jumpers, relay retaining bracket and marking fields.
PR3 Bases
The PR3-B relay bases are available in two different designs with screw terminations: The PR3-BSC1/2X21 type for DPDT octal relays as well as the PR3-BSC1/3X21 type for 3PDT octal relays. The PR3 pluggable modules with keying can be used to provide different indication and protection.
Rugged octal relays
Available with a 10 A (per pole) DPDT or 3PDT in AC and DC coil voltages
Standard features for our octal relays include the following:
Manual test button (AC coil = red button, DC coil = blue button), mechanical switch position indicator, as well as keying
