RT-2 DPDT Relay The RT-2 is a Sensitive Double Pole Double Throw relay with heavy-duty 5A contacts. The Coil requires only 40 mA to energize two sets of 5A contacts. The RT-2’s Coil has a MOV across it to protect your sensitive electronics from the spike that is generated from most other relays. The RT-2 has a BI colored LED across the coil that lights when energized, regardless of polarity. This makes installation easier. No spade lugs are required with our self-clamping screw terminals. TERMINALS and OPERATION Coil Terminals (Coil) Input Power to energize relay. May be 12 VDC or 24 VDC, Polarity does not matter. Select voltage before applying power. Move jumper to the left 2 pins for 12 VDC. Move to the right 2 pins for 24VDC. LED ON indicates the relay is energized. When the LED is OFF the relay is de-energized. The LED has 2 green LED’s back to back so the color will be green with either polarity. COM 1 & COM 2 Terminals are the common or swing arm connection to the contact sets 1 and 2. N/C 1 & N/C 2 Terminals are the relay’s normally closed contacts. COM and N/C are Normally Closed; they open when relay is energized. N/O 1 & N/O 2 Terminals are the relay’s Normally Open contacts. COM and N/O are Normally Open; they close when relay is energized.
