Dual-Channel Radio Control Interface

£46.20

The DMR-203 is a general purpose dual-channel radio-control interface providing proportional motor speed control from a standard radio control system. It accepts two standard Pulse Position Modulated inputs from the RC receiver and converts these to a suitable signal to operate two of our controllers, such as the DNO, PRO or 4QD ranges.

Description

The DMR-203 is a general purpose dual-channel radio control interface providing proportional motor speed control from a standard radio control system e.g. Spektrum, Futaba etc. It accepts two standard PPM inputs from the RC receiver and converts these to a suitable signal to operate two of our controllers, such as the DNO, PRO or 4QD ranges.

Applications include

  • Robots
  • Model railways
  • Model tanks
  • Remote controlled vehicles
  • Special effects
  • Other applications where powerful motor control via radio is required.

Features

  • Mixed or tank style steering modes.
  • Dead-band areas on both centre and full stick positions.
  • Configurable failsafe system.
  • Switched or proportional output modes, with reverse drivers.
  • Signal validation and rejection for noise immunity.
  • Inputs optically isolated.
  • Low power consumption.
  • Compact and lightweight design.
  • Supplied with connectors and cable as diagram.

Suitable Controllers

The DMR-203 may be used directly with

  • DNO
  • VTX
  • Pro-120
  • 4QD series
  • Porter 5/10 by using this diagram

For controlling a Pro-150 the DMR-213 should ideally be chosen. However the DMR-203 can be made to work by following the notes on this page.
