The MOD-IO8 is a modular unit, featuring 8 configurable I/O (input/output) ports with spring terminals for quick and easy, yet secure connections. Plug it into a modular controller to add I/O ports to your system.

Each port can be customised into any of the following input or output modes:

• Dry Contact Input
• Resistance Reading Input (0 - 10,000 Ohms, in 100 Ohm increments)
• Voltage Reading Input (0 - 10 Volts DC, in 0.1V increments)
• Digital Voltage Input - detect presence of voltage (30V DC MAX)
• Video Sensing Input - configurable detection range (0 - 10V DC)
• External Relay Output (0 - 24V DC, external power supply required)
• LED Output (5V DC, 1mA)

Front of the module has four detachable screw terminal blocks.
