Compact monitoring relays for quick wiring
10 February 2014
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.
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.
