Description
FDC L Series High Limit Control FDC-L91 is a 1/16DIN control designed to provide limit protection in process applications.
Up to three discreet setpoints, two outputs, fast scan rates, and user-friendly prompts make it the right choice for safety protection. The FDC-L91 offers a full range of universal inputs. Power supply selections of 90-264 VAC (std) or 11-26 VAC/VDC allow the FDC-L91 to be used virtually anywhere.
Output selections include Relay, SSR Drive, or Triac. Optional features such as a second latching relay, DC power supply, remote reset, or communications offer maximum flexibility for demanding applications. The FDC-L91 display can be configured for PV, HSP, LSP, or Safe, offering the simplicity required by operations personnel.
