EMERSON KJ3201X1-BA1 | DeltaV Dry Contact Input Module

📝 Product Description

The EMERSON KJ3201X1-BA1 is a DeltaV Series 2 discrete input module designed for monitoring dry-contact field signals in industrial process-control systems. It provides 8 digital input channels for 24 VDC dry-contact applications and is used with the Emerson DeltaV I/O architecture. The module is identified as a DI, 8-channel, 24 VDC dry contact card and is associated with the Series 2 DeltaV I/O platform.

The module is suitable for applications where field switches, relay contacts, status contacts, and other discrete devices need to be monitored by the control system. Emerson documentation identifies the card keying as B1, helping maintain compatibility between the I/O card and the appropriate terminal block. The field circuit specification is 24 VDC at 5 mA per channel.
