STRUTHERS-DUNN A311XBXPR24A Industrial Plug-in Sequence Relay
The Struthers-Dunn A311XBXPR-24A is a robust industrial plug-in sequence relay, part of the 311 series. This relay is a sequencing version of the 219 series general purpose relay, transferring contacts on each coil impulse. It's designed for applications requiring precise timing and control, with models available that transfer contacts when the coil is energized or de-energized. The double cam movement allows for reliable sequencing of the two snap switches. It is suitable for a wide range of industrial automation and control systems.
