elobau extends the application possibilities of the compact systems 171 K1 B1 with the new compact unit 171 K4 B1. It can be operated with 230 V instead of 24 V and may be integrated into machines where there is no low voltage supply due to cost or space constraints.
elobau maintained all the benefits of the 24 V model, among them the integrated evaluation electronic. It offers a direct, potential-free control output and a safety output which can handle up to 250 V AC/30 V DC/2.5 A/625 VA/75 W. Both compact units 171 K4 B1 and 171 K1 B1 are especially small and easy to install with a length of 81 mm and a M30 diameter of the TO-style can. Due to the high damping distance of 7 mm they are especially suited for the monitoring of protection doors and hatches.
Both compact units from elobau are fitted with a two-colored LED which signals the relevant status. The user can spot at a glance if the unit is ready for operation or if there is a fault. The devices can be operated in a temperature range of -25 °C to +70 °C. They belong to the safety class SIL 2, PL d and protection class IP 67.
