Description
Product Description
Overview
The KJ3243X1-BB1 (12P3430X022) is a high-density, 32-channel discrete output module for the DeltaV™ Series 2 Distributed Control System. Designed to drive 24 VDC field devices such as solenoid valves, relays, and indicators, this module enables efficient space utilization and high system reliability. The redundant design ensures seamless switchover to a standby card in the event of a hardware failure, preventing process interruptions.
Key Features
High-Density Output Control
-
Provides 32 discrete output channels in a single module, reducing I/O cabinet footprint
-
Manages 24 VDC high-side switching with low internal heat generation
-
Supports large-scale valve manifolds and multiple field devices from one slot
Redundancy and High Availability
-
Operates in hot-standby mode when paired with a second card
-
Automatic failover transfers output control to the redundant card within one scan cycle
-
Maintains output state during hardware failures to prevent unintended shutdowns
Smart Diagnostics and Safety
-
Monitors for open or short circuits on each channel
-
Readback verification confirms the commanded On/Off state matches the actual output voltage
-
Protects DCS backplane via galvanic isolation between field outputs and controller logic
Rugged Industrial Design
-
Hot-swappable for zero downtime maintenance
-
Operates in harsh industrial conditions with an ambient range of -40°C to +70°C
-
Engineered for reliability in continuous process environments

FAQ
Q: Can this module be replaced while the system is powered?
A: Yes, it is hot-swappable, but redundancy requires correct seating on a compatible redundant terminal block.
Q: How is output state verified?
A: The module reads back the actual voltage at each terminal to confirm the On/Off state.
Q: What is the maximum current per channel?
A: Typically 100–500 mA, depending on total load and simultaneous device activation.
Q: Does the card support redundancy?
A: Yes, dual-card configuration enables seamless automatic switchover during a failure.
