Product design
NAMUR isolating amplifier
• The NAMUR isolating amplifier is designed for the operation of proximity switches
(according to EN 60947-5-6 (NAMUR)) and open and mechanical contacts with
resistive coupling elements. One relay (changeover) per channel is available as a signal
output. The power supply is designed as a universal power supply (UP).
• The device is optionally available with Ex approvals for the intrinsically safe operation of
proximity switches installed in the hazardous area. Separate Ex documentation (XA) is
supplied with these devices. Compliance with the installation instructions and
connection data in this documentation is mandatory!
• The device is optionally available for safety-oriented applications up to SIL 2 in
accordance with IEC 61508.
• A resistive coupling element (1 kΩ / 10 kΩ) is available as an optional accessory and can
be used to monitor line faults of sensors with mechanical contacts. The resistive coupling
element is installed onsite directly at the contact to be monitored or in the sensor
connection compartment.
