It accepts 4-20 mA current-loop signals and converts them to 16-bit binary data — that's a resolution of 1 part in 65,536 across the full span, so a 4-20 mA transmitter outputting 12 mA at mid-scale resolves to roughly 32,768 counts. Each channel is isolated from the backplane, but the module does not provide per-channel field-to-logic isolation — adjacent channels share a common return. If your transmitters sit on different ground potentials, budget an external isolator per loop. The screw-terminal strip accepts up to 14 AWG stranded wire; no special crimp tool or ferrule is required, though ferrules keep the strands tidy in high-vibration panels. At 140 g and roughly the width of a single CJ-series CPU slot, it leaves room alongside for output modules and a communications unit in the same rack. The backplane connector is keyed to the CJ-series passive bus — it auto-negotiates the I/O refresh cycle on insertion. ## Approvals and compliance documentation Carries CE (EU low-voltage and EMC directives), cULus (US and Canada safety listing), Lloyd's Register, and Nippon Kaiji Kyokai (NK) marine type approval. For a panel destined for a shipboard or offshore installation, the Lloyd and NK marks satisfy the classification society surveyor without a separate component-level certificate chase.","metaTitle":"Omron CJ1W-AD041-V1 Analog Input Module, 4 Ch, 16 Bit","metaDescription":"Omron CJ1W-AD041-V1 analog input module, 4 channels, 16-bit resolution, 4-20 mA, DIN rail mount, screw terminal.
