Littelfuse COM 4-20MA Series

 Littelfuse COM 4-20MA Series Analog Comm Link for Model 777-AccuPower

from Flow Factor

The Com 4-20mA Output Module is intended for use with ONLY the Model 777-AccuPower output power monitor. The module will send a 4-20mA signal proportional to the output power. It can also be used to send the input power by setting the efficiency setting on the 777-AccuPower monitor to one. This module allows communication to a PLC with an analog input and no Modbus input.

The Littelfuse 777-AccuPower is a fully-programmable 3-phase motor and pump protection relay. It allows motor hp rating, full load amps, efficiency and power factor to be entered and will accurately calculate motor output power. This is most useful with mag-drive pumps or process applications where the process power is desired over the utility power. Voltage, current and power measurements can be displayed as well as fault information and setpoints. The built-in display simplifies troubleshooting and allows the user to easily and precisely configure setpoints. The Littelfuse 777-AccuPower can be used with the optional COM 4-20 output module to give an analog signal proportional to output shaft power, the RS485MS-2W (for limited Modbus capabilities, and for use with the RM1000/RM2000) remote displays listed in the 777 accessories section.

Features & Benefits:

Motor output power measurement 

Allows use of process power over utility power 

 

3 programmable restart delay timers 

Program separate restart delay time for rapid cycle protection, motor cool down, and dry-well recovery

Littelfuse ACBC-120 Alarm Controller for Pumping

Littelfuse ACBC-120 Alarm Controller for Pumping

from Flow Factor

For a Quote, Please click HERE!

The Littelfuse ACBC-120 is a dual purpose alarm controller/battery charging unit. When there is a loss of 120VAC power, the ACBC-120’s primary function as an alarm controller activates. When this power loss occurs, input power is switched to a 12VDC, lead-acid, rechargeable backup battery and a 12VDC alarm consisting of a strobe light and/or a horn is activated. The horn follows a 2 second on/2 second off pattern with a “horn silence” option to turn the sound off. An LED indicator on the unit also signals that the device has entered the alarm mode.

When 120VAC input is present the alarm circuit can be tested and the Littelfuse unit’s secondary function as a 12VDC backup battery charger is activated. In fast charge mode, the unit has the capability to source up to 100mA of charging current. However, the device normally charges at a current of 14mA in maintenance mode. The alarm circuit can be tested by pressing the “test” button located on the front of the unit or by activating an external switch via the “alarm contact” pin.

The device has the ability to signal low battery voltage if the voltage drops below 10.5VDC. The device can also detect if no battery is present or if the battery is connected backwards. In either of these cases, the Littelfuse ACBC-120 will signal a battery error and will not attempt to charge. The Littelfuse ACBC-120 requires a Rectangular 12 pin socket. for surface mounting.  Littelfuse part number is SD12-PC.

 

Features & Benefits

Controls 12VDC alarm circuit >> Activates strobe and/or horn when power loss occurs 

Selectable fast charge mode >> Unit sources higher charging current up to 100mA (normal mode is 14mA) 

Trip delay timer >> Prevents nuisance tripping

Battery fault detection and reverse polarity protection >> Signals if battery voltage drops below 10.5VDC and can detect if no battery is present or if the battery is connected backwards 

LED Indication >> Visual indication of unit status or trip 

Test button >> Preventative maintenance check of the alarm circuit by pressing the test button on the unit or externally through alarm contact connection
