Presentation
Functions
These devices are designed to detect when a preset voltage threshold is exceeded, on a.c. or d.c. supply.
They have a transparent, hinged flap on their front face to prevent any accidental alteration of the settings.
This flap can be directly sealed.

relay
RM4-UA0i
RM4-UA3i
Applications:
- d.c. motor overspeed control,
- battery monitoring,
- monitoring of a.c. or d.c. supplies,
- speed monitoring (with tacho-generator).

Adjustment of voltage threshold as % of setting range max. value.
Hysteresis adjustment from 5 to 30 % (2).
Adjustment of time delay as % of setting range max. value.
Switch combining:
- selection of the timing range: 1s, 3s, 10s, 30s, no time delay,
- selection of overvoltage (>) or undervoltage (<) detection.
