DI-16 Central IO Module
This Central IO module is a digital input, 16-channel I/O module. You can use the digital inputs for sensing of multiple dry contact digital inputs in applications such as equipment status monitoring or alarm point monitoring. As counter inputs, digital inputs are commonly used in energy metering applications.
The following input types are supported:
Digital (dry contact, open collector, or open drain)
Counter (dry contact, open collector, or open drain)
Each channel has a dedicated two-color (red and green) status LED that provides local monitoring of the input. You can configure the channel status LED for a digital or counter input to display either red or green for each input state. The front panel contains both the I/O channel and module status LEDs.
Digital inputs
The digital inputs (DI) 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.
