The Emerson KJ3203X1-BA1 is a digital input (DI) card from the DeltaV series by Emerson Automation Solutions. It is specifically designed for industrial control and automation applications. The KJ3203X1-BA1 DI card provides 32 channels of digital input, and each input supports a 24 VDC dry contact configuration.

The card is used to interface with digital input signals from various field devices, such as sensors, switches, and other equipment that provide discrete on/off status indications. It allows the DeltaV system to receive and monitor the state of these digital signals for control and monitoring purposes.

Each channel on the KJ3203X1-BA1 DI card supports a 24 VDC dry contact input. This means that the card is suitable for applications where the input signals are provided by devices that utilize a voltage source of 24 volts direct current (VDC). Dry contact refers to a type of electrical contact where no additional power is supplied by the card to the connected device; it simply detects the state (open or closed) of the contact provided by the external equipment.

With its 32-channel capacity and compatibility with 24 VDC dry contact inputs, the Emerson KJ3203X1-BA1 DI card enables the DeltaV system to receive and process a large number of digital input signals, making it suitable for a wide range of industrial applications
