These are high quality sealed Single Pole - Double Through (SPDT) relays. This relay's coil is rated for 24V.
This is a High current driver that will take TTL signals from your Arduino, etc to drive the relays. It includes status LEDs for each input. 5V, 12V, and 24V relay options are available. This item replaces TE-010-405 and TE-010-412
Powered by the ULN2003 high current driver, this module gives you easy control of up to 7 relays using TTL logic from an Arduino, Beagle Bone, or Raspberry Pi. 5V, 12V, and 24V relay options.
