The device can withstand positive and negative supply voltages up to ±60 VDC. In case of overvoltage, undervoltage, overcurrent or reverse-input polarity, the device is switched off and the red diode on the HOST board (at the 24VDC section) is illuminated.
Page 57 Analog input/output dip switches Analog outputs can operate in two modes accordingly to NAMUR NE43 and EN 15267-3:2007. SITRANS TDL generates the failure signal at the level of 3.3 mA. NAMUR NE43 provides guidelines for signaling failure information to the safety-interlock systems over a 4 to 20 mA loop.

Active analog outputs need no external power supply of the output terminal. SITRANS TDL provides power supply for the active analog outputs and thus analog outputs MUST NOT BE powered externally. Please set the dip switch to Active (A) before powering up the system.
Page 59: Passive Analog Outputs
Active analog inputs need no external powering of the input terminal. Set analog input dip switch to A (active) before powering up the system. SITRANS TDL provides power supply for the active analog inputs and thus analog inputs MUST NOT BE powered externally.
