Compact monitoring relays for quick wiring
The new EMD-BL compact monitoring relays from Phoenix Contact monitor current, voltage, and phase sequence efficiently and reliably. They are in a space-saving installation housing and equipped with Push-in quick connection technology, facilitating, quick, tool-free wiring. They are particularly suitable for simple monitoring tasks from series production through to building installations.
The product family includes four types of devices: For single-phase networks, there is a voltage monitoring relay with measurement ranges up to 24 V AC/DC and 230 V AC, in addition to the current monitoring relays for alternative currents up to 10 A. In three-phase networks, an additional voltage monitoring relay detects AC voltages up to 400 V/230 V AC with adjustable measurement ranges. A phase monitoring relay indicates errors in the phase sequence, phase failure, and asymmetries in networks up to 480 V AC/277 V AC.
All parameters, such as the tripping delay, can be easily adjusted using the rotary switch located on the front. Also, the highly readable LEDs provide for quick on-site analysis. Besides the quick connection technology, there are versions which need no external supply, as it is taken from the measuring circuit are particularly quick and easy to install.
In summary: A compact product with easy installation make new EMD-BL monitoring relays an ideal choice.
