Q & A

The Relay Board allows the implementation of much higher voltages and currents to be controlled from a single port on the existing I/O 24 Range.

Tempero I/O 24 Range consists of Ether I/O 24 R, Ether I/O 24 DIP R, USB I/O 24 R and the USB I/O 24 DIP R

The Relay board consists of eight Panasonic JW series 12v Coil relays with both normally open and normally closed contacts. The relay coils are powered from an external 12V DC power supply capable of producing at least 700mA (each relay consumes about 80mA when active). The relay coils are controlled using the ULN2803 via the I/O port of the module.

The board has been designed to a 72mm standard width so that it can easily be mounted in DIN rail  mounting modules swell Board has been updated  with  3 Extra  Din Rail  Mounts  DIN Rail Mounting Clips, Narrow Plastic
