Hi! We are looking for a relay switch that can be controlled via dry contact inputs (ie, output from another device). Preferably something DIN rail mountable. We have a 24VDC power supply in our system. Any direction would be appreciated. Thank you!

Hello,

This link has some good options using a typical 1 or 2 form C switch.
