MTL7796- MTL Instruments Intrinsically Safe Zener Barriers Safety Isolator​

MTL7700 range barriers protect devices located in all normally occurring explosive atmospheres, including air/flammable gas mixtures, dusts
and fibres. Applications covered include the protection of installations incorporating uncertified devices (‘simple apparatus’) such as thermocouples, switches and resistive sensors, or separately certified ‘energy storing’(or ‘voltage producing’) apparatus including ac sensors, transmitters and current-to-pneumatic (I/P) converters. Recommended choices for specific applications are discussed briefly in the following pages.

• 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–.
