Product Overview
The Emerson VE4036P2 is a Redundant M-series Serial Interface Card designed for DeltaV™ distributed control systems. It enables reliable communication between DeltaV systems and third-party devices using serial protocols such as Modbus (RTU/ASCII), RS232, and RS422/485. The model includes two serial interface cards (KJ3241X1-BA1 and KJ3241X1-EA1) and a redundant terminal block for high-availability applications. This redundant setup ensures automatic switchover during hardware failure, maintaining uninterrupted data transmission.
