MODEL: 18HZ 18HZ SPECIFICATIONS ES-1870 Rev.6 Page 1/3 http://www.m-system.co.jp/ Rack-mounted DCS Signal Conditioners 18-RACK FREQUENCY TRANSDUCER Functions & Features
- Providing two DC output signals in proportion to deviation (±5 Hz) from center frequency (50 Hz or 60 Hz)
- DC output containing little ripple is ideal for computer input Typical Applications
- Centralized monitoring and control of power management system in manufacturing facility or building
- Measuring frequency for UPS MODEL: 18HZ–[1][2]66–R
