Product Description
Overview
The KJ3203X1-BA1 (12P3162X132) is a Series 2 discrete input module designed for the DeltaV™ Distributed Control System. It interfaces directly with 120/230 VAC field signals, converting them into high-integrity digital inputs for the controller. This module eliminates the need for interposing relays and reduces overall cabinet complexity while maintaining redundancy and reliability in critical control applications.

FAQ
Q: Can the module be replaced while the system is running?
A: Yes, it is hot-swappable without interrupting adjacent cards or process operation.
Q: What is the isolation rating for field signals?
A: The module provides 1500 V peak isolation between field inputs and logic circuits.
Q: Does it support both 120 VAC and 230 VAC inputs?
A: Yes, it is designed for global voltage standards with direct field interfacing.
Q: How does redundancy work?
A: Two cards installed in a redundant terminal block operate in parallel; if the active card fails, the standby card takes over immediately.
