• 2-channel isolated barrier
• 24 V DC supply (Power Rail)
• Input 2-wire SMART transmitters
• Output 0/4 mA … 20 mA
• Terminals with test points
• Up to SIL2 acc. to IEC 61508

This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire SMART transmitters in a
hazardous area.
It transfers the analog input signal to the safe area as an
isolated current value.
Digital signals may be superimposed on the input signal in the
hazardous or safe area and are transferred bi-directionally.
If the HART communication resistance in the loop is too low,
the internal resistance of 250 Ω between terminals 8, 9
and 11, 12 can be used.
Test sockets for the connection of HART communicators are
integrated into the terminals of the device
