PHOENIX CONTACT UM-2KS50/DI16/RS/K-MT/SO241 

16-Channel Digital Input Module

 with M12 Connectivity

Robust, Field-Wired Sensor Interface for Harsh Industrial Environments

The PHOENIX CONTACT UM-2KS50/DI16/RS/K-MT/SO241 is a specialized 16-channel digital input module designed for efficient and reliable connection of sensors in demanding automation applications. Part of the versatile INLINE and PHOENIX INPUT family, this module stands out with its integrated M12 connection technology, drastically reducing installation time and providing a superior, vibration-proof interface for sensor cabling.

It is the ideal solution for applications in automotive manufacturing, material handling, packaging, and process automation where a high number of sensors need to be connected quickly and reliably to a control system via a serial bus.

Key Features & Technical Specifications

• Product Type: Digital Input Module (Sinking/Sourcing, configurable)

• Number of Channels: 16

• Input Voltage: 24 V DC (Nominal)

• Input Configuration: Configurable per channel (Sinking or Sourcing)

  • This flexibility allows the module to interface with both PNP (sourcing) and NPN (sinking) sensors without hardware changes.

• Signal Level "1": 15...30 V DC

• Signal Level "0": -30...5 V DC

• Input Current: Typically 3 mA per channel (at 24 V)

• Electrical Isolation: 500 V (Channel-to-Bus)

• Connection Technology (Sensor Side): 4 x M12 5-pin A-coded circular connectors (K-MT)

  • Each M12 connector interfaces with 4 sensors, allowing for fast, pre-wired, and rugged field connections.

  • Provides high protection against vibration, moisture, and dirt (IP67 rating at the connector when mated).

• Connection Technology (Control Side): Screw Clamp (SO241)

  • The system power (24V) and the RS-485 communication bus are connected via a removable pluggable terminal block with screw clamps, ensuring a secure and reliable main connection.

• Module Interface: RS-485

  • Enables serial communication and allows the module to be daisy-chained with other devices on a single bus, minimizing wiring effort.

• Mounting: INLINE Terminal Block

  • Snaps onto a standardized 35 mm DIN rail for compact and organized panel building.

• Diagnostics: LED Status Indicator per Channel

  • Provides clear visual feedback on the status of each input (signal ON/OFF), enabling rapid troubleshooting.

• Approvals: CE, cULus, ATEX, IECEx

  • Certified for use in a wide range of industrial environments, including potentially explosive atmospheres (Zone 2).

Ordering Information
