Overview / Design Principle:

The RIM Signal Switcher enables the use of one drive with two separate encoders, switching between encoder inputs as needed. Its optically isolated inputs accept signals from two different voltage levels, including signals from differential line drivers, open collector, and even proximity probes. It has a wide input voltage range of 4-26 VDC and high power differential adaptive line driver outputs. It can switch seamlessly from one encoder to another in just microseconds and can also convert signals between high and low voltage levels.

The Switcher can also perform signal level conversions from low to high or high to low voltages. It has thermal, under voltage, reverse polarity, and overload protection and a fail-safe mode which directly connects input terminals through dry contacts during power losses and faults. Its front panel has a status indicator showing normal operation and encoder selection. The Signal Switcher is approximately three by five inches in size and mounts with DIN 32 or 35 mounting hooks.

Features and Benefits:

  • Eliminating need for two PLCs or input devices
  • May switch two encoders of different resolutions coarse and fine position control
  • Can select spare encoder that acts as backup of first
