Narrow Line Monitoring Units

The RayDat Narrow Line (NL) signal protection solutions feature a narrow and compact design that is just 6.2mm wide. The transmitter (NMU-TX) and receiver units (NMU-RX) are used together with various RayDat Narrow SPDs to provide remote monitoring capabilities for all product variants. RayDat products meet the diverse requirements of industrial applications with various signal types and operating voltages. Single modules can be added or replaced without interrupting the operation of others in the stack.

A Monitoring Transmitter Unit (NMU-TX) & Receiver Unit (NMU-RX) placed on either end of the stack will check the status of up to 50 SPDs in a row.
