Hubbell Industrial Controls 47AB10AG Relay 318423-701 The proportional 2-10 VDC controlThe Hubbell Industrial Controls 47AB10AG Relay is a heavy duty alternating relay designed for industrial grade motor control and HVACR redundancy. Operating on a 208 240V AC coil voltage at 50 60 Hz, this Type 5247 series device provides an essential 1 SPDT contact configuration to effectively cycle two separate loads. By alternating the lead and lag operations of pumps or compressors, it ensures equalized runtime and prevents uneven wear, which is a
