DIO

Digital Input / Output

Device Description

DIO (Digital Input/Output) Module can display on/off or 1/0 data for up to 16 channels. Input channels with high impedance reduce the input current and noise immunity is increased through hysteresis. The device has a anti-jumping filter to prevent contact from jumping. The device also has 32 bit change registers and these registers display the level changes in the input channels. DIO (Digital Input/Output) has 8 channels of isolated solid state relay output. Output channels are isolated from each other. The output type can be changed to latch or unlatch output with the specified time. The user can configure input polarities, anti-jumper filter time, serial communication port settings and output latch time easily through DIO user interface. User can also turn the “Test Mode” on the module. All the inputs and outputs are adjustable for site tests in the “Test Mode”.
