The discrete output I/O package IS420YDOAS1B provides an electrical interface between up to two Ethernet input/output networks and one discrete output terminal board. The kit can control up to 12 relays and receive feedback specific to the terminal board. All inputs for the I/O packet will be sent via the dual Ethernet RJ454 connector as well as the three-pin power input. The DC37 pin connector is used for the output, which will be connected directly to the associated patch board connector. If a visual diagnosis is required, it will be provided via an LED indicator on the front of the package.

IS420YDIAS1B

As mentioned above, the IS420YDOAS1B I/O package can provide diagnostic leds; Typically, the 12 leds will be yellow to indicate that each output command is powering the relay. The BBPx processor LED will also be used to indicate the required diagnostics. There is an ATTN LED, which will be red or green and either steady on or blinking. Some modes of the green ATTN LED are 2 Hz 50% and two 4 HZ pulses every 4 seconds; The latter mode means that the application is online and running on demand.

Various common diagnostic alerts pop up during the operation of the IS420YDOAS1B package, such as two, three, and five. All of these alarms have different causes and solutions, the description, cause and potential solution of alarm five is that the I/O packet is in remote I/O mode, some of the reasons for this are hardware failure, the module configuration of the I/O packet may be invalid, to fix these errors, Replace the I/O packages or modules completely or rebuild the system and reconfigure the I/O packages.

Features:
The discrete input acquisition board provides the second level signal conditioning and level conversion, connecting the terminal board input to the control logic. Initial signal conditioning is provided on the terminal board.
Discrete input acquisition The input circuit is a comparator with a variable threshold. Each input is isolated from the control logic by optical coupler and isolated power supply. Inputs are not isolated from each other.
Each of the 24 inputs has a filter, hysteresis, and yellow status LED to indicate when the input is picked up. When the input is disconnected, the LED will go off.
The input threshold is derived from the contact wetting voltage input terminal. In most applications, this voltage is adjusted to provide a 50% input threshold. The threshold is clamped to 13% to prevent uncertainty when the contact wetting voltage drops to zero.
If the contact wetting voltage drops below 40% of the nominal voltage, the undervoltage detector notifies the controller of this. Provides a special test mode to force the input of the control group.
Every four seconds, the threshold is high, followed by a low pulse, and the response of the optical coupler is checked. Unresponsive input is alerted.
