Further product information
The contact protection relays operate according to the closed-circuit current principle, i.e. if there is no overflow or leakage signal, an operating current flows via the transmitter. As long as this is the case, the output relay remains energised. It only drops out when either the response level is reached, the line is interrupted or the supply voltage fails.
The contact protection relays are used in conjunction with our overfill prevention devices (T200F...) and leakage probes (T200L...), among others.
In potentially explosive areas, the contact protection relay serves as an interface between the Ex and non-Ex areas. The intrinsically safe circuit is galvanically separated from
the non-intrinsically safe circuit. The contact protection relays themselves (without additional protective measures) must not be operated in hazardous
areas. When installed in an Ex-approved enclosure, operation in the Ex-area is possible. The safe isolation has been tested and certified by TÜV.
- Design approved as part of an overfill protection system (Z-65.11-404) / leakage protection system (Z-65.40-153)
- Line monitoring (cable break / cable short circuit) in connection with our overfill / leakage probes
- Safe galvanic isolation between input, mains and contacts
- Various supply voltages
- 1 and 2 channel relay
- 19" card version
- TÜV ATEX approved (KR-163/A/Ex...)
System structure
The overfill protection or leakage detection system consists of the level sensor (T200F...) or the leakage probe (T200L...) and a contact protection relay.
