CTPH

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
