RM17UAS and RM17UBE
In the intricate landscape of modern electrical systems, ensuring the stability and safety of power supplies is paramount. The RM17UAS and RM17UBE 1-phase voltage measurement and control relays represent a pinnacle of engineering excellence designed to safeguard electronic or electromechanical devices against overvoltage and undervoltage conditions. These devices, by monitoring their power supply with true RMS values, offer a layer of protection and control that is essential in today’s high-demand environments. Ideal for a wide array of applications, from HVAC machinery protection to emergency power supply switching, these relays are versatile tools for maintaining electrical integrity.
1-phase voltage measurement and control relays RM17UAS•• and RM17UBE •• monitor:
Depending on the model, control relays:
- Allow selection of operating mode
- Monitor their own power supply measured as a true rms value
- Are designed for clip-on mounting on a ⍽ rail
They feature:
- A sealable cover to help protect the settings
- A control status indicator LED
Applications
- Protection of electronic or electromechanical devices against overvoltage and undervoltage
- Emergency power supply switching at abnormal conditions
- Anti short-cycle for compressor used in HVAC machinery

Operating Principles
Voltage control relays RM17UAS (except RM17UAS15315M) and RM17UBE monitor:
- Voltage of 1-phase and DC supplies
- RM17UASpp relays support two operating modes:
- Overvoltage or undervoltage
- Fault memory selected or not
- An adjustable time delay, on crossing the thresholds, provides immunity to transients, and helps prevent spurious triggering of the output relay
- Fault signaling is by LED
RM17 UAS14/UAS15/UAS16 (except RM17UAS15315M)
The operating mode is determined by a switch:
- Undervoltage with or without memory
- Overvoltage with or without memory
The position of the configuration switch and the operating mode is read by the product on energization:
- If the configuration switch is set to an unacceptable position, the product detects a fault, the output relay stays open and the LEDs flash to indicate the position error.
- If the switch position is changed while the device is operating, all the LEDs flash, but the product continues to operate normally with the function selected at the time of energization preceding the change of position.
- If the configuration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state
The undervoltage or overvoltage threshold value is set by a graduated potentiometer clearly indicating the voltage Un to be monitored. The hysteresis is adjusted by a potentiometer graduated from 5…20% of the threshold setting. The hysteresis value must not exceed the limit values of the measuring range.
Undervoltage/Overvoltage without memory
If the controlled voltage falls below the threshold setting for a time greater than that set on the front panel (0.1…10 s), the output relay opens and the R LED goes off. As soon as the voltage returns to a value above (or below) the threshold setting minus (or respectively plus) the hysteresis, the relay instantly closes.
If the controlled voltage exceeds the threshold setting for a time greater than that set
on the front panel (0.1…10 s), the output relay opens and the R LED goes off. As
soon as the voltage returns to a value below the threshold setting plus the
hysteresis, the relay instantly closes.

Overvoltage + undervoltage control in window mode
These relays operate in window mode where they check that the controlled voltage stays between a minimum threshold and a maximum threshold.
- The undervoltage or overvoltage threshold values are set by two graduated potentiometers clearly indicating the voltage Un to be monitored. The hysteresis is fixed at 3% of the threshold setting.
- If the controlled voltage exceeds the high threshold setting, or falls below the low threshold setting for a time greater than that set on the front panel (0.1…10 s), the output relay opens and the R LED goes out. During the time delay, this LED flashes.
- As soon as the voltage falls below the high threshold setting value minus the hysteresis, or rises above the low threshold setting value plus the hysteresis, the relay instantly closes.
- On energization of the device with a detected measured fault, the relay stays open.
RM17UAS15315M
Undervoltage
If the controlled voltage falls below the threshold (165 V a), the output relay instantly opens and the R LED goes out. As soon as the voltage returns to a value above the threshold plus the hysteresis, the relay closes after the time set on the front panel (3…15 min).

Operating Principles
RM35 UA11MW/UA12MW/UA13MW
Multifunction voltage relays RM35UA1 MW:
- Automatically recognize the form of ⎓ or ∿ (50 or 60 Hz) signal
- Fault signaling is by LED
The operating mode is selected by using a switch:
- Undervoltage with or without memory
- Overvoltage with or without memory
The position of the switch and the operating mode is read by the product on energization:
The position of the switch and the operating mode is read by the product on energization:
- If the switch is set to an unacceptable position, the product detects a fault, the output relay stays open and the LEDs flash to indicate the position error.
- If the switch position is changed while the device is operating, all the LEDs flash, but the product continues to operate normally with the function selected at the time of energization preceding the change of position.
- If the configuration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state
The undervoltage or overvoltage threshold value is set by a potentiometer graduated as a percentage of the scale value of Un to be monitored. The hysteresis is adjusted by a potentiometer graduated from 5…50% of the threshold setting. The hysteresis value must not exceed the limit values of the measuring range.
Overvoltage/undervoltage without memory
If the voltage controlled exceeds the threshold setting for a time greater than that set on the front panel (0.3…30 s), the output relay opens and the R LED goes off. During the time delay, this LED flashes. As soon as the voltage drops below the value of the threshold setting, minus the hysteresis, the relay instantly closes.
If the voltage controlled falls below the threshold setting for a time greater than that set on the front panel (0.3…30 s), the output relay opens and the R LED goes off. During the time delay, this LED flashes. As soon as the voltage rises above the value of the threshold setting plus the hysteresis, the relay instantly closes.
Note: Tt: time delay after crossing of the threshold (adjustable on front panel)
Overvoltage/undervoltage with memory
If “Memory” mode is selected, the relay opens when crossing of the threshold is detected and then stays in that position. The power needs to be switched off to reset the product.
