Description:

• Ex universal measuring isolating transformer and trip amplifier for RTD/TC temperature and DC current/voltage signals. This is a 1-channel measurement isolating transformer and trip amplifier with an external power supply that measures 22.5 mm in width. It is designed to capture and isolate signals from RTD/TC sensors, resistors, potentiometers, and DC current sources. Ex zones 0, 1, 2, and voltages 0...12 V and 0(4) ... 20 mA.
• It is possible to supply sensors using the 0...20 mA current loop.
• The output can be used as a passive 4...20 mA current loop or as an active 0(4) ...20 mA signal.
• On the output side, there is a relay contact (NO) for monitoring limit values.
• Relay contacts are used to send out error and status messages (NO).
• The component can be set up with the help of common FDT and DTM software.
• Extension housing for the TS35 rail installation
