 ABB DSDI 115 57160001-NV Digital Input Unit The ABB DSDI 115 57160001-NV is a digital input unit designed for use with ABB S800 I/O system or AC 800M controllers. It is part of ABB modular I/O solution for industrial automation systems and is specifically designed to handle digital inputs from field devices. It receives and processes digital signals from field devices and sends these signals to the controller for further processing. It is used in systems where devices such as limit switches, push buttons, proximity sensors, and on/off control devices need to be monitored or controlled.It is capable of receiving signals from a variety of digital field devices that require binary data inputs, including contact closures and electrical signals. DSDI 115 units are typically equipped with 16 channels, each of which can be independently configured to process digital signals. The DSDI 115 typically supports a wide range of digital input voltages, 24V DC for industrial applications, but other voltage levels are also supported, depending on the field device. The digital signal is processed by the I/O unit, which converts it into a signal that the controller can understand for control logic or decision-making processes. The system can then trigger actions or monitor system status based on the state of the digital input. The unit typically has galvanic isolation between the input channels and the controller, which helps prevent ground loops and electrical interference from affecting the system. This isolation improves the reliability and safety of the I/O system, especially in harsh industrial environments.Frequently asked questions about the product are as follows: -How many digital input channels are there on the DSDI 115? The DSDI 115 offers 16 digital input channels. -What types of devices can be connected to the DSDI 115? The DSDI 115 can be connected to binary field devices that produce discrete on/off signals, such as limit switches, proximity sensors, push buttons, emergency stop switches, or relay outputs from other devices. -Is the DSDI 115 isolated from the controller? The DSDI 115 typically has galvanic isolation between the input channels and the controller, which helps prevent electrical interference and ground loops from affecting the performance of the system.
