The JUMO STB/STW (701150/9-02-0253-1003-23/005) is a safety temperature limiter for shipboard control systems. It acts as the protective stage that guards heated plant against excess temperature. The unit is set up for one Pt100 sensor on a 2-wire connection, works with a 4-20 mA signal and covers a 200-500 °C range. The STB “O” setting is marked on the unit. Power comes from an AC 110-240 V supply at 48-63 Hz, which suits standard shipboard control voltages. The limiter is supplied in used condition.
