WOODWARD SPEED SWITCH SA-3678-LL-2
Woodward’s ESSE Series are single channel (ESSE-1) or two channel (ESSE-2) electronic speed switches with exceptional power transient protection. The units are potted for protection against harsh environments and have proven to be reliable and rugged as well as flexible and cost effective. In generator set applications, the ESSE Series can be used for crank (starter motor) disconnect or overspeed protection, or for underspend and overspeed warnings. In fact, most speed-related switching functions on diesel and gas engines and other rotating machinery can be accommodated by ESSE speed switches. The speed switches can receive signal input from a magnetic pickup, alternator, ignition coil, or Woodward’s Mini-Gen signal generator.
