GO/NO Current Status Sensor w/Command Relay


Product Description:

The ACI/R225 is solid state adjustable status current sensors with a command relay. The R225 current sensor is excellent for new installations, the conductors runs through the housing, requiring no cutting. The current sensor is accurate, reliable, easy to install, and requires less service than differential pressure switches, flow switches, and paddle wheels.

The R225 can sense continuous currents from 1 to 250 amps. The sensor does not require any supply voltage, all power required is induced from the monitored conductor. The sensor provides both a normally open status output as well as a command relay. The command relay is a Form C relay rated to 5 Amps at 250 VAC. This sensor does not include an LED Indicator or trip point adjustment.

All R225 current sensors come with a 5 year unconditional warranty.

A current sensor monitors fans, pump, motors, and electrical equipment for proper operation. The ACI/R250 senses any change in current. A change in current may indicate motor failure, belt loss/slippage, or mechanical failure. Any time one of these events occurs, the current can drop significantly, tripping the sensor, and notifying the controller. Some monitoring applications include:
Fans, Pumps, and Heating elements
Ancillary Equipment
Lighting circuits
Control and sense most EMS, HVAC,
low-horsepower motors
