Features
1. Upgraded composite function
Specified-period measurement and total-time measurement can
be monitored on a single hour meter.
2. High-performance compact syncronous motor
The accurately turning motor is employed to provide for longer
period of measurement.
3. Common for 50/60 Hz power frequency
A lever is used to select 50 Hz or 60 Hz. There is no need to
rearrange the control panel and other signal destinations.
4. Dimensions as per DIN 43700 standard
The units are in the 48 × 48 DIN standard size. They can be fit-
ted in panels and give refined metallic appearance.
5. Easier wiring
The flat terminals (#187) are quick and easy to connect.
6. Rotary indicator
The rotary indicator makes one turn every 2 minutes for moni-
toring.
7. Compliant with CE.
