SMART Transmitter Power Supply
Opis
This isolated barrier is used for intrinsic safety applications. 2-channel isolated barrier, 24 V DC supply (Power Rail), Input 2-wire SMART transmitters, Output 0/2 V .. 10 V, Terminals with test points, Up to SIL 2 acc. to IEC 61508pa. The device supplies 2-wire SMART transmitters in a hazardous area. It transfers the analog input signal to the safe area as an isolated voltage 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.
