The Zelio RM22 control relay range brings to market 2 new key improvements.
- The backlight LED dials for adjustment makes it easy to use in any condition, even in dusty or poorly lit enviroments.
- The built-in testbutton simplifies commissioning and troubleshooting by a push of a button.
RM22TA33 is a 3-phase control relay for phase sequence, phase failure detection and asymmetry.
The measurement is made directly through the supply terminals L1, L2 and L3 on the top of the relay.
The relay has 3 illuminated dials for setting up the function of the relay.
On the top dial you select the measurement range between 380 and 480V.
The value is set to the voltage between 2 phases
The middle dial adjust the off-delay on the output and can be between 0,1 and 30 seconds.
On the bottom dial, the maximum allowed asymmetry in voltage between the 3 phases is set.
This value can be between 5-15% of the voltage limit set on the top dial.
The relay has 2 LED's on the front which indicates if a fault is detected (Def) and the state of the relay output (R).
The testbutton force the output when the timer is powered on.
