Honeywell CTP Data Sheet
CTP Current Transmitters
FEATURES
• Split core loop-powered current transmitters for
simple installation.
• High accuracy and linearity.
• Selectable scaling on most models for greater
measurement accuracy.
• Fast response time.
• Integral DIN rail mounting flange.
APPLICATION
The CTP current transmitters monitor the current flow for
various electrical equipment. Measured current level is
converted into a linear and proportional 0 - 5/10 Vdc or
4-20 mA output signal, which can be monitored by a
Building Management, DDC, or PLC controller. Current
sensors with switch selectable current ranges provide
optimal resolution for greater measuring accuracy. These
current sensors should be used in load trending (current
monitoring) type applications.
The split core design makes installations easy since no
wires need to be disconnected during the installation
process. May be mounted directly on the conductor (codes
permitting) or fixed mount on DIN rail.
Typical load status applications include:
• Load trending
• Monitoring process motors and pumps
• Electric heater current monitoring
• Easy wiring, polarity sensitive output.
• Optional slide on command relay for unitary startstop status.
• Limited 5-year warranty.
