MTL The MTL7756AC is a Zener-type safety barrier, part of the MTL7700 series. The following is a brief introduction: - **Features**: It utilizes a two-stage pulse-detected Zener or forward-connected diode and terminating resistor design. In the event of an electrical fault in the safe zone, it limits the voltage and current reaching the hazardous zone. A fuse protects the diode, and the two-stage voltage limiting function ensures continued protection even if a fault occurs in any stage. Channel resistance is 19Ω per channel, minimizing range variation. Channel line resistance is within 0.15Ω, minimizing temperature-induced zero drift. - **Signal Type and Application Scenarios**: Suitable for inputs such as RTDs and thermocouples. It is particularly well-suited for use with floating bridge resistors to protect three-wire RTDs. It can be used in industrial environments with flammable and explosive hazards, such as the petroleum and chemical industries, to effectively isolate field circuits in the hazardous zone from control systems in the safe zone. - **Operating Voltage**: The supply voltage is 24VDC, with a maximum safety voltage of 2.7VDC. - **Safety Parameters**: Maximum safe current 300mA, safe current resistance 10Ω, maximum safe area voltage 250V. - **Mounting Method**: DIN rail mounting, wiring via plug-in safe and hazardous area connectors, or a power bus power plug for simplified wiring. - **Dimensions**: Approximately 122mm × 18mm × 96mm. - **Weight**: Approximately 0.4kg.
