The 4PDR is a 24 Volt 4 Pole Double Throw Relay used for various control functions to control dampers. Most commonly this is used when multiple AOBD series dampers are required to be slaved together to operate from a single zone. It also is used when more than 4 or 5 spring return dampers are slaved together and isolates power transformers from requiring phasing. The 4PDR socket has screw terminals and can be mounted on a DIN rail and uses the PIRR Relay.
