MINI MCR-2-NAM-2RO-PT - Isolation amplifier

2902005

Configurable NAMUR signal conditioner with plug-in connection technology for proximity sensors, floating switch contacts, and switch contacts with resistance circuit. 2 transistor outputs. Configurable via DIP switch. Push-in connection technology.

Configurable NAMUR 4-way signal conditioner with plug-in connection technology for operating proximity sensors in accordance with EN 60947-5-6 as well as floating and resistance-circuit switch contacts. Two transistor outputs are available on the output side. The second output can be used either for duplicating signals or for signaling faults on the sensor line. You can configure the signal conditioner via DIP switches. The device supports fault monitoring and NFC communication.
