Plug-in Signal Conditioners M-UNIT

CT TRANSMITTER

(true RMS sensing; high speed response; peak hold)

Functions & Features

• Converts an alternating current from a current

transformer into a standard process signal

• Dual output: The second output can be switched to ‘peak

hold’ mode with the front DIP switch

• Resetting the peak hold output with the front reset control

button

• CT Protector provided for open-circuit protection

• True RMS sensing with fast 50-millisecond

response time (0 – 90 %) is possible

• Isolation up to 2000 V AC

Typical Applications

• Monitoring impulsive power line voltage change
