The network monitoring relays are used to monitor single-phase to three-phase networks. When used in a three-phase network, the phase position can also be monitored in addition to the voltage. The switching threshold can be freely set from 150 to 230 V or to a defined fixed value of 196 V (DIN VDE). The NKR 5 indicates the state of the phase voltages and the direction of rotation via 4 LEDs. A phase failure is visually indicated by a blinking LED. The relay either automatically switches back on after voltage recovery or only after acknowledgment by the internal or an external button (fault memory function). Dimensions: 18 x 55 mm, 230 V AC, 1 changeover contact 10 A potential-free, Uvar 150-230 V, Ufix 196 V.

6. Schalk SCHAL MGR U2 Motor group relay 230VAC 2 CO contact 5A
Discover the Motor Group Relay MGR U2, a practical solution for electrically connecting up to 2 roller shutter or blind motors to a single control. With this relay, you can combine multiple motors into a single operable group without needing a separate control for each individual drive.
Simple and cost-effective, the MGR U2 provides 2 complete up/down outputs for the direct connection of 2 motors. This allows you to easily and affordably group your roller shutter or blind motors and control them conveniently together.
Reliable functionality: A mutual locking mechanism for the outputs ensures that only one direction of operation can be switched to the motors at any time. This guarantees reliable and safe operation of your roller shutters or blinds.
Flexible mounting options: The MGR U2 is designed for flush mounting and can be easily integrated into your existing electrical installation. Its compact dimensions of 43x43x18.5 mm allow for discreet integration into your spaces.

The ATR U2 allows for the simplest control of mains voltage consumers through low voltage contacts. A power supply for actuating the relay coil is not required, as the ATR U2 internally generates the necessary control voltage (24V DC PELV). In conjunction with the magnetic contact MKW 1, it is thus possible to implement a supply air monitoring system, often required for enclosed spaces, when operating exhaust fans with minimal effort. However, due to the 10A changeover contact, the ATR U2 is also very versatile for other applications. Dimensions: 43x43x18.5 mm, 230V AC - 1W 10A.
