  1. Current Sensors

  2. Introduction • Honeywell is proud to introduce its new line of current sensors and switches. • Current sensors and switches detect whether current is flowing through electrical equipment, such as pumps and motors. • Detects when equipment is turned on or off. • Transmits the status to a building management system, DDC or PLC controller. • The wires are threaded through a hole in the current sensor which measures the current going through the wire. • Current sensors and transmitters can be used to detect a motor failure, belt loss or slippage, or a mechanical failure.

  3. Key Features • Higher operating range (250A) and very low trip points- down to 0.12 Amps • Integral DIN rail mount • Solid core and split core models • Quick signal allows for service actions to be taken immediately to prevent damage and reduce downtime • Current sensors are rated at 250 amps, allowing you to meet high-amp situations without needing transformer • UL rated • 5-year warranty

  4. Key Features TRANSMITTER Jumper Selectable Current Range SWITCH Solid core Split core UL rated DIN Rail integrally mounted

  5. Installation • Easy to install and service • Built-in DIN rail mounting flange simplifies installation • Red and green LEDs – on adjustable switches. Red indicates over the trip point, green indicates below.

  6. Current Switches • CSS solid and CSP split core fixed and adjustable trip points • Monitor fans, pumps, motors, compressors, or other electrical equipment. • Change in current can trip the sensor to indicate equipment status or alarm condition. • Up to 250 Amps. • Do not need to be externally powered, since the power for the • switch is induced from the conductor being monitored. • Red LED – Indicates above the trip point on fixed models. • Red and Green Status LEDs – indicate above or below trip point on adjustable models.

  7. Current Sensors (Transmitters) • CTS solid and CTP split core 4-20mA, 0-5 and 0-10Vdc • Solid core excellent choice for new installations • Split core ideal for retrofit or existing installations • Linear proportional output signal, can be monitored by your Building Management, DDC or PLC controller. • Available in either an Average or True RMS (for VFDs) output version. • Jumper selectable input ranges except for the 0 to 5 Amp input range. • Current sensors can be used in load trending (current monitoring) type applications. • Sensors are fast acting, reliable and extremely easy to install. • No additional DIN rail mounting clips are necessary, due to the unique design of the integral din rail mounting flange. • All of the CTS20 and CTP20 series current sensors are factory calibrated using a NIST Traceable standard • The CTS20 and CTP20 must be externally powered using a 12 to 35 Vdc power supply.
