DI-16 I/O Module
The DI-16 I/O 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 I/O 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 I/O 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 I/O module and the SmartStruxure server device.
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 utilizes the same hardware configuration as the digital input as shown in the figure above.
