ETR4 timing relays control machines and systems to an accuracy of a hundredth of a second in a wide range of timing functions.

All the relays in this range are only 22.5 mm wide. When combined with contactors and contactor relays, they can be used as an ideal space saving solution for virtually all timing requirements.

Seven different types ensure the right solution for every application. The ETR 4-69 and ETR 4-70 are the most versatile relays in the range. They can be set for nine different functions and ten timing ranges.
