OC32 Light and Movement


The OC32 is an electronic module for direction of a range of components in the miniature world. This module has 32 outputs that can be used universally for very diverse tasks. For increasing the power per output special modules can be added.

With use of the OC32, light bulbs, LEDs, servo motors and DC motors, among others, can be directed in both ways. Several interfaces allow for the using the OC32 in combination with the MCC car system, within the Dinamo system and with any system making use of the DCC connection. The module can however be used independently for light and movement.

The functions in the OC32 allow for the module to be used for nearly all accessories found surrounding the miniature world:

  • Signalling in both bulb and LED editions for a range of signalling systems;
  • Blinking lights and alternating blinking lights for e.g. railway crossings or roadblocks;
  • Traffic lights;
  • Lighting of e.g. buildings and streets;
  • Special effects such as light from welding, electric arc or fireplace;
  • Day/night simulation;
  • Switches and electronic detachers with automated disengagement;
  • Electric motors, with adjustable turning speed and direction, e.g. driving motor-switch connections;
  • Servo motors, both in simplistic and dynamic fashion.

Complex devices such as railway crossings with several servo motors, blinking lights on the poles and barriers, and bells can easily be directed because the OC32 is able to combine the wide range of functions.

Light control
Using the OC32 both light bulbs as LEDs can be switched.

In addition to the standard on/off functions, blinking effects can be created. The light’s intensity can be directed using software, in which an on- and afterglow effect can be imitated and a dark phase can be set at a signalling image or traffic light.

Servo control
The OC32 knows both simplistic and dynamic servo control.
With the simplistic control, the servo is directly placed in a defined position.
Using the dynamic control, a wide range of situations from the real world can be imitated very lifelike and real. Examples are:

  • The slow changing of a switch or opening/closing of a gate;
  • Slow operating and afterward bobbing of arm signals and crossing barriers;
  • The rebound of a door of a warehouse or garage against a door stop after opening/closing.

The OC32 can posses both an RS485 and a DCC interface that can be used simultaneously. The RS485 interface is for connection to a USB port (through a uniquely developed U485 converter) of a PC or connection to an MCC/Dinamo system. A DCC interface is for directing of every digital system supporting DCC accessories.

The diverse connections to different systems enables placement of the OC32 close to the accessories to be directed, no matter what system is directing it. The functions of the accessories to be directed can be set using a configuration tool. For many used functions device definitions that can be inserted in the OC32 are already available.

OC32 editions
The OC32 is available in 3 different editions:

  • OC32NG/A  : Basic edition with preparation for amplifier modules;
  • OC32NG/D  : Edition with the DCC interface, without preparation for amplifier modules;
  • OC32NG/ADE: Edition with the DCC interface, Event Inputs and preparation for amplifier modules.

The OC32 module offers the possibility to control up to 32 servo motors. A servo can use up a lot of power, making it unwise to connect these to the power supply of the OC32. Instead, it is advised to provide a separate power supply for the servos.

The SP04R is a compact module, meant to provide power to 4 servo motors and easy connection to the OC32.
For connection of more then 4 servos to an OC32, utilization of multiple SP04R modules is preferred.
