Yokogawa 3081 Hybrid Recorder

The Yokogawa 3081 is a second-generation hybrid paper chart recorder engineered for industrial data acquisition in process control, monitoring, and optimization environments. This desktop instrument delivers simultaneous multichannel recording across 30 DC input channels at 6 seconds per channel with 6-color output capability. The unit accepts maximum input voltages of 20 V or 100 V DC and operates on 100 V, 115 V, 200 V, or 230 V AC at 50 or 60 Hz, drawing approximately 40 VA.

Built for long-term operational stability in demanding applications, the 3081 integrates directly into existing Yokogawa systems and supports DCV, TC, RTD, DI, and DCA input types.
