A311XBXP-120VAC

**311 Series - Industrial Sequencing** DPDT, 5 Amp 

File No. ES2197 

The 311 Series relays are sequencing (stepper) relays built on the industrial 219 style frame.  Hold down clip is integral to the relay base.  Double pole contacts transfer on energizing of coil or de-energizing.  Dual cam movement allows contacts to operate together or separately.  Works equally well with application of continous voltage to coil or energy saving impulse.  No continuous voltage required for memory. Numerous custom switching arrangements are possible over 8 steps per revolution of the cams.
