8x Relay Output Board US$77.00

Relay-BRD
8x Relay Output Board


The 8x Relay Output Board is an accessory that allows much higher voltages and currents to be used by I/O board modules.

The board consists of 8 relays with both Normally Open (N/O) and Normally Closed (N/C) contacts rated to 250V AC or DC at 5 Amperes. The relays' coils are powered by an external 12V DC supply that is capable of producing approximately 700mA. (A power supply is not provided with the board. See below for compatible power supplies.) The relay coils are controlled using a ULN via the I/O ports of the module. Each of the output port channels has an LED which serves as indicator for the relay output status.

The connections for each output channel are N/O, COM and N/C. These connections are by screw terminals that will accept cables from 0.5mm to 2mm wide. The connection between the I/O module and the relay output board is via a 30cm, 2x5 IDC header connection cable. This cable is provided with the board.

The board has been designed to a 72mm standard width so that it can be mounted in DIN rail mounting modules.

8x Relay Output Board Features

  • 8x 12V DPDT 250V AC / 30DC @ 5A Relays
  • Indicator LEDs for relay output status
  • Screw Terminal Blocks for relay outputs and 12V power input
  • Easy connection to the I/O port through a 0.1 pitch 10-way box header
  • 72mm standard width for DIN Rail Modules
