Plug. Wire.
Replace.
N232x digital output modules feature removable, pluggable terminals. Wire the terminal once. If a module needs replacement, remove the terminals, swap the module, and plug the terminals back in.
No rewiring. No relabeling. Reduced wiring-error risk. Minutes instead of hours.

Wire the terminal once. During replacement, pull off the terminals, swap the module, and reattach the same terminal blocks.
Part of a platform
N232x is an optional module for the N-Series distributed I/O system and must be used with a suitable fieldbus coupler, such as a BL210 Series coupler.
What makes N232x different
Removable terminals. 32 channels. Industrial reliability.
The N232x combines removable spring-cage terminals, 32 digital output channels, individual channel LEDs, electrical isolation, and industrial EMC protection.
Removable terminals
The field wires stay attached to the terminal block during replacement, dramatically simplifying service.
Service efficiency
Replace a module in minutes instead of spending a long time removing, labeling, and reconnecting wires.
32-channel output
Select N2321 for PNP high-level active output or N2322 for NPN low-level active output.
Industrial-grade design
2 kVrms isolation, IP20 protection, EMC protection, and -20°C to 55°C operation.
N232x models
Choose PNP or NPN output.
N2321 provides 32-channel PNP output with high-level active 24 VDC output. N2322 provides 32-channel NPN output with low-level active 0 VDC output.

Maintenance comparison
The removable-terminal difference.
Compare replacement workflow, downtime, wiring-error risk, and maintenance requirements.
Traditional fixed-terminal I/O
Replacement workflowRemove every wire, label it, reconnect it, and then test for errors.
Typical downtime30–60 minutes per replacement.
Risk levelHigh risk of wiring mistakes and polarity errors.
Maintenance burdenUsually needs an electrician or trained technician.
N232x with removable terminals
Replacement workflowRemove the terminal block, swap the module, reconnect the terminal block, and finish.
Typical downtime2–5 minutes per replacement.
Risk levelLower risk because the field wires remain connected to the original terminal block.
Maintenance burdenCleaner maintenance and fewer service headaches.
Minutes instead of hours. No rewiring. No relabeling. Reduced wiring-error risk.
N-Series module family
More N-Series I/O module options.
The N-Series includes digital input, digital output, analog input, analog output, RTD, temperature, pulse, and power modules.
I/O modules can be arranged in different combinations within the distributed I/O station without grouping them by module type.
