OMRON R88A-FI1S216 Three-Phase 16A Noise Filter for 1S Servo Drives

The OMRON R88A-FI1S216 (R88A-FI1S216) is a three-phase noise filter engineered for use with OMRON 1S Series servo drive systems. Designed to suppress electromagnetic interference and high-frequency electrical noise, this input EMC filter prevents disruptive electrical disturbances from feeding back into the AC power line or affecting sensitive peripheral automation equipment. By attenuating conducted emissions on the incoming mains supply, the filter contributes to operational reliability, signal integrity, and standard compliance across automated industrial installations. Operating with a rated current of 16 A, the unit is matched to three-phase power supplies in drive-controlled machinery, packaging equipment, assembly stations, and precision motion control systems. It installs on the power input side of compatible 1S servo amplifiers to deliver robust noise suppression in harsh electrical environments. Integrating this dedicated filter reduces unwanted drive line noise, prevents sporadic communication or sensor faults, and safeguards neighboring control hardware throughout continuous motion control duties.
