DI-16 Central IO Module
The DI-16 Central IO module is a digital input, 16-channel I/O module. Each channel has a dedicated two-color (red and green) status LED that provides local monitoring of digital and counter input types.
You can configure the channel status LED to display either red or green for each input state. The front panel contains both the I/O channel and module status LEDs.
Inputs
The inputs of the DI-16 Central IO module are designed to read two different types of inputs:
Digital
Counter
Applied voltages beyond the absolute maximum ratings cause over current in the protection component D Z .
The I/O bus in the terminal base provides the Central IO module with power and an address.
The address value in the I/O bus is increased by one for each terminal base. The I/O bus also enables RS-485 communication between the Central IO module and the automation server.
The external connection of a digital input is shown in the following figure:
K is the monitored external switch.
V S = 24 V
R PU = 10 kohm
A counter input uses the same hardware configuration as the digital input that is shown in the figure above.
