Installation-ready highlights

Sixteen isolated field inputs, one compact module.

16 Isolated Channels

Helps reduce interference and improves reliable field signal.

Per-Channel Indicators

Each input channel includes a front LED indicator for easier monitoring.

External Trigger Supply

Supports digital input operation using external 12–24VDC trigger wiring.

CAN-BUS Integration

Works with SmartAPEX DIN-rail modules and MINI-IP through CAN-BUS.

Dry Contact Support

Suitable for contact-based signals such as switches, relays and sensor outputs.

Compact DIN-Rail Form

Designed for cabinet installation with front access and simple wiring.

Per-Input Configurable Timer

Every input channel has its own internally configurable timer — no external timer hardware needed.

Product overview

Signal collection for smart panels and industrial automation.

The APX-DI16-BA collects dry-contact and digital input signals, reports them over CAN-BUS and integrates easily with SmartAPEX controllers and distributed cabinet systems.

Distributed Input Expansion

Add 16 field input points to SmartAPEX DIN-rail systems with one compact module.

Contact Input Focus

Designed for contact-style monitoring, including open/close status collection from sensors and outputs.

Status Visibility

Front LED indication supports channel-level visual checking during commissioning and service.

Industrial Fit

Suitable for building automation, security/status monitoring and utility signal collection.

External Trigger Ready

Designed to work with external 12–24VDC trigger methods, as shown in the application schematic.

SmartAPEX Ecosystem

Integrates with SmartAPEX DIN-rail modules and MINI-IP through CAN-BUS.

Application map

Typical usage scenarios.

Motion & occupancy sensors

Collect contact outputs or compatible digital status signals from motion and occupancy devices.

Door / window contacts

Monitor magnetic contacts and status contacts for security or automation logic.

Panel / equipment status

Read dry-contact status from third-party devices, relays, breakers or alarm outputs.

General automation inputs

Use as a distributed contact-input interface for cabinet and field automation tasks.

Use case summaryDistributed contact monitoring, sensor signal collection and field-status input expansion for SmartAPEX cabinet systems.

Sample schematic

Reference wiring concept.

The supplied file included a sample schematic showing CAN-BUS connection, AC supply and external 12VDC trigger wiring for sensor / contact use.

Sample wiring schematic showing AC power, CAN-BUS network and external 12VDC sensor triggering from the installer manual
Reference concept from the installer manual. For actual wiring, follow the supplied connection concept and project electrical design, not this figure.
  • AC powerThe sample schematic shows the module powered from AC line input.
  • CAN-BUS networkThe module exchanges data with the SmartAPEX network using CAN-BUS.
  • External 12VDCAn external 12VDC source is used in the sample concept for input triggering / sensor power.
  • Sensor examplesThe schematic shows AC motion sensor and DC motion sensor examples, plus any other compatible contact-output sensor type.

Project note. Always validate polarity, common reference and sensor output type before final field wiring.

How to position the module

Best used as a distributed field input collection point.

The APX-DI16-BA is best used as a distributed field input collection module inside the SmartAPEX ecosystem.

System Integration

Connect the module to compatible SmartAPEX DIN-rail modules or MINI-IP using CAN-BUS. Use it as a remote contact-input expansion point for automation logic, monitoring or supervisory workflows.

Binding / Direct Control

Bind individual inputs directly to other SmartAPEX CAN-BUS devices — keypads, relay channels, thermostats and DIN-rail modules — for local, controller-free automation logic.

Typical Input Sources

Dry contacts, magnetic contacts, motion sensor outputs, equipment alarm outputs, relay feedback contacts and other open/close status signals — when their electrical behavior matches the supported wiring method.

Installation notesUse proper terminal tightening, cable labeling, common reference management and electrical protection according to the site electrical standard.
Commissioning notesVerify input LED response channel by channel. Confirm CAN-BUS communication and upstream controller recognition during setup.
