MTL7796 MTL 24V 0.6W Instruments Intrinsically Safe Zener Barriers

MTL7796- MTL Instruments Intrinsically Safe Zener Barriers
 

• Product type : Zener Barriers

• Analogue inputs (high level)

• 2-wire transmitters, 4/20mA, conventional and smart

• The recommended barrier for use with 'conventional' and 'smart' 4/20mA transmitters (fed by a 26V regulated supply) is the MTL7787+.

• This provides up to 12.9V (14.6V for MTL7787P+) at Vwkg and 20mA for a transmitter and its lines as well as 5V for the typical 250O load.

• This application and this barrier is suitable for use with the optional power bus facility.

• The MTL7706+ is recommended for applications where an unregulated supply of up to 35V is used. It provides 16.0V for conventional and smart transmitters at 20mA, as well as 5V for a typical 250O load.

• With the MTL7706+ terminal 3 is negative with respect to earth, so the connections to terminals 3 and 4 should be reversed.

• Vibration probes

• The 3-wire transmitters used with vibration monitoring equipment are invariably supplied by a –24V dc power supply – hence the recommended barrier choice is the negatively-polarised MTL7796–.
