PPC-L156T Introduction

The PPC-L156T is a 15" fanless panel computer which is the ideal solution for low noise operating environments and clean room applications. PPC-L156T has two power sources; an optional battery pack and AC power supply. The battery charges when the PPC-L156T is connected to the AC power adapter. The optional rechargeable battery pack has more than 60 minutes battery life and can be used as an UPS during expected loss of power. The PPC-L156T meets the VESA standard for mounting holes so it can be used in many different kinds of installations. The front bezel can be removed to make maintenance of the LCD and touchscreen easier and quicker.

PPC-L156T Features

  • 15 inch TFT XGA LCD
  • Embedded IntelŽ ULV CeleronŽ M 1.0 GHz/PentiumŽ M 1.1 GHz
  • Support for up to 2 GB Double Data Rate (DDR) memory
  • Two built-in 1 W speakers
  • Fanless and ultra-low power consumption
  • Automatic data flow control over RS-485
  • Removable front bezel
  • Optional Smart Battery Module with UPS functionality
  • Optional wireless antenna and one optional PCI expansion kit


Tomeet the requirements of a public environment, the front panel of PPC-L156T complies with the IP65/NEMA4 protection standard. The watchdog timer and power management features make the system secure and stable. The onboard hardware monitoring feature provides automatic protection that prevents the CPU from overheating.


Three serial ports and a 10/100 Mbps Ethernet port (Gigabit optional) give the PPC-L156T advanced networking capabilities, and provide a great solution for versatile applications.


To extend functionality, the PPC-L156T is designed with one expansion slot for 32-bit PCI cards, one mini-PCI socket, four USB 2.0 (Univeral Serial Bus) ports, two RS-232 ports, one RS-232/422/485 port, one VGA port, and two PCMCIA CardBus ports. With these expansion capabilities, the PPC-L156T not only functions as an HMI, but also as a computing center to build your applications on.
