Product Information
The Lenze 13515985 EPM-S110.1D.32 is a 4-channel digital input module belonging to the Lenze I/O System 1000 series. Designed as a compact slice-format component for 35 mm DIN rail mounting, this module acquires digital discrete signals from 24 V DC PNP sensors in automated machinery. It incorporates direct 3-wire sensor connection capability, integrating signal acquisition and sensor power distribution directly within the terminal block. Featuring an IP20 protection rating and modular backplane connectivity, it serves as a decentralized input expansion solution across packaging, material handling, and general machine building systems.
Physical field wiring connects via tool-free push-in spring cage terminals, allowing direct 3-wire sensor attachment without external potential distribution blocks. Interfacing with control networks occurs through the internal System 1000 backplane bus, drawing 65 mA at 5 V DC, linked to fieldbus couplers supporting EtherCAT, PROFINET, PROFIBUS, CANopen, or Modbus TCP. When commissioning a replacement unit, the two-piece module construction allows the electronic component to be swapped without altering field wiring on the terminal base. Automatic parameter management stored in the primary bus coupler configures replacement modules upon power-up, allowing support teams at ABC Industrial Parts to guide smooth hardware replacement.
Diagnostic information is presented directly on the front panel through channel and module status LEDs. Dedicated channel LEDs indicate logic high (24 V DC) and low states, while the module status indicator confirms backplane bus health and internal operational readiness. Supplementary software diagnostics are accessible through Lenze EASY Starter and I/O mapping flags within Lenze PLC Designer. If a module indicator signals a persistent bus or hardware failure, field-level servicing of internal electronics is not feasible, making an exchange unit the most direct pathway back to full operation.

Programming and Configuration
Configuration and monitoring of the Lenze 13515985 EPM-S110.1D.32 digital input module are performed using Lenze engineering suites such as EASY Starter and PLC Designer. Input mapping flags within PLC Designer allow software tasks to read channel states and evaluate signal validity across the automation program.
The module operates under non-volatile parameter management maintained by the primary I/O System 1000 bus coupler. Operating parameters and network node configurations are pushed from the head module across the internal backplane bus, enabling straightforward setup during initial commissioning or system maintenance.
Communication and System Integration
The EPM-S110.1D.32 integrates into modular station assemblies via the Lenze I/O System 1000 internal backplane bus, drawing a low current of 65 mA at 5 V DC. The backplane provides high-speed data transfer between discrete I/O modules and the connected fieldbus head coupler.
Network integration across broader plant architectures is handled by combining the module with System 1000 fieldbus couplers. Supported protocol interfaces include EtherCAT, PROFINET, PROFIBUS, CANopen, and Modbus TCP, allowing discrete 24 V DC sensor signals to be transmitted across diverse industrial fieldbus structures.
Diagnostics and Status Indication
Operational monitoring for the Lenze 13515985 EPM-S110.1D.32 is provided through multi-color faceplate status LEDs alongside fieldbus-level software diagnostic utilities. Channel LEDs labeled 1 through 4 display green when standard 24 V DC PNP signal inputs register logical active status and turn off when inactive.
The dedicated module status LED labeled DI provides overall hardware and system bus health verification. Green indicates normal operation, red indicates a module or backplane communications error, and off indicates a complete loss of power supply. Detailed error logs are also transmitted via the bus coupler to EASY Starter or PLC Designer.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| 1 ... 4 | Green / Off - Solid / Off | Green = Channel active (Logical 1 / 24 V DC present); Off = Channel inactive (Logical 0) |
| DI | Green / Red / Off - Solid / Flashing / Off | Green = Module operating normally; Red = Module fault or system backplane bus error; Off = No power supply |
Replacement and Spare Part Considerations
When replacing a damaged or failed Lenze 13515985 EPM-S110.1D.32 module, maintenance personnel can replace the electronic component without disconnecting field wiring. The two-piece mechanical structure detaches directly from the DIN rail terminal base, preserving existing push-in spring cage sensor wiring.
A replacement module does not require manual parameter programming prior to installation. Upon seating the module into the I/O System 1000 backplane bus, the head fieldbus coupler automatically identifies the hardware and restores saved parameters. ABC Industrial Parts provides tested replacement units to restore operations with minimal machine downtime.
Frequently Asked Questions
What sensor connection method does the Lenze 13515985 EPM-S110.1D.32 support?
The module features direct 3-wire sensor connection using push-in spring cage terminals, allowing signal lines and 24 V DC sensor power distribution to connect directly without auxiliary terminal blocks.
Is manual programming required when installing a replacement EPM-S110.1D.32 module?
No, manual parameter programming is not required. The primary I/O System 1000 bus coupler maintains non-volatile parameter management and automatically configures the replacement module upon power-up.
Which fieldbus networks are compatible with the Lenze 13515985 input module?
The module integrates with Lenze I/O System 1000 fieldbus couplers supporting EtherCAT, PROFINET, PROFIBUS, CANopen, and Modbus TCP.
What do the faceplate LEDs on the Lenze EPM-S110.1D.32 indicate?
The numbered LEDs (1...4) indicate channel active status (green for logical 1, off for logical 0). The module status LED (DI) indicates normal operation (green), module or backplane fault (red), or no power supply (off).
What software tools are used to monitor and diagnose this module?
System monitoring and diagnostic checks can be performed using Lenze EASY Starter engineering software and Lenze PLC Designer software suite.
