Amplifier relay
ES 2001


- Protection of Reed contact
- Outputs: 2 change over contacts, voltage free; 5A / 250 V AC / 500 VA
- Status relay display
- Regulation between two trigger points
- Adjustable time delay
PRINCIPLE
All Reed contacts suffer of inductive or capacitive charge due to starting pumps or motors, leading to early aging and malfunction.
A solution is to protect Reed contacts with a relay amplifier, to insure greater switching power and lifetime.
ES 2001 amplifies commutation signals on low current and low voltage detection loops, e.g. by use of Reed contacts. Mounting: on DIN rail for easy integration in industrial cabinets. On the front a LED displays the output relay status. This relay ES 2001 is also perfect for liquid detection or liquid level regulation (documentation 530-01).
APPLICATIONS
ES 2001 relays are designed for:
- Reed contact, models included in BRK60, MNR6, MNR7 etc.
- Flow switch, such as Z42 (IDP – PDP), CDP etc.
 
Each relay allows a regulation between two trigger points. For instance to fill in or emptying a tank by automation of a pump (or a valve). Each relay has 2 outputs change over contacts, potential free to allow driving for example, a power loop or an automate.
