45C43 Information: |
Reliance Automax. In stock ships today. 45C43. 4543. Input/Output. Optically Isolated Inputs. All input logic level circuits are optically isolated from field signals. These high threshold circuits will not energize until a pre-determined voltage is reached, to prevent triggering by false signals from external interference. Input module voltage ratings for the 45C43 are 230 VAC/DC. This module compares two analog voltage signals and sends the logical results to the processor. It can also compare an external voltage to a preset reference voltage determined by the user. Both greater-than and less-than comparisons are made.
