The Opto Input Board is a handy accessory that allows the user to connect signals from 3 to 24V AC or DC to the I/O ports of either the USB I/O24 or the Ether I/O  via 8 optically isolated input channels.

Each of the input channels is electrically isolated from all other channels, and the IO24 Module preventing signals from other channels from interfering with each other and damage the IO24 Module.   The input channels also have LED’s to indicate when a signal is present on the channel.

The connections to the Opto input board’s input channels are by screw terminals that will accept cables 0.5 – 2 mm. The connection between the I/O24 module and the opto input board is via a 30 cm IDC connection cable. This cable is provided with the board.

BOARD FEATURES:

• 8 x Opto Insulated Inputs for each of the IO24 Module port pins
• LED indication for Opto status
• Screw Terminal Blocks for Opto inputs
• Easy connection by 0.1″ pitch 10-way box header to suit standard IDC connectors for connection to the I/O port on the I/O 24 Modules.
• Dimensions 4.3 X 2.8 inches (110 X 72 mm)

Power Input Requirements to Opto Board:

• Power is drawn from +5V @ 80 mA max

Opto Isolated Input Electrical Characteristics:

• Logical Input High Voltage 3 to 24V AC or DC
• Logical Input High Current 1mA to 12mA
• Optically isolated to 7500 VAC (peak)
