MTL7789+| Instruments | Proximity Detector Interface
For switching inputs with input currents <10mA per channel, the MTL Zener Safety Barrier MTL7789+ provides a two-channel passive Zener barrier. All MTL7700 series Zener barriers are designed according to the same design principles. Each channel consists of a secondary pulse detecting Zener or forward connecting diode and a “reliable” terminating resistor. In the event of an electrical fault in the safety zone, the diode limits the voltage that can reach the hazardous area, while the resistor has a current limiting effect. A fuse protects the diode, and a two-stage voltage limiting function ensures continuous protection in the event of a failure in either stage. No active output current limiting circuitry is used. All models are certified “ia” - for all zones and “IIC” - for all explosive atmospheres (except MTL7707P+ and MTL7729P+, “ia” “IIB”).
