Switching amplifiers for Namur sensors
NAMUR switching amplifiers evaluate a sensor signal and transmit a switching signal to the controller. They meet the requirements of many international directives for use in hazardous areas. Switching amplifiers are available with relay outputs, active transistor outputs or potential-free optocoupler outputs. The amplifiers are designed for the connection to NAMUR sensors according to DIN EN 60947-5-6 and mechanical switches. They provide the supply voltage for the intrinsically safe circuit.
Features & Benefits
- One- or two-channel design
- Reliable short-circuit and wire-break monitoring
- Easily programmable output functions
- Relay or transistor outputs
- Quick and easy mounting
