Availability: Obsolete
OBSOLETE LC4-family Single-board Controller, 120 VAC

Production Specification

This part is obsolete and no longer available. Please contact Opto 22 Pre-Sales engineers to discuss options for your specific application.

------------------------

The LC4 family of controllers provides powerful, low-cost, single-board computers which function as local controllers on a Pamux or Optomux network. The LC4A controller uses onboard 120 AC power. For 220 VAC power, use the LC4B controller. Also available is the LC4DC controller, which requires a 10-28 VDC power source.
