All-In-One Flow Indication, Totalizing and Alarm
Complying with RoHS

IR4600
UNIVERSAL TOTALIZEROUTLINE
IR4600 is an indicator and a totalizer used in combination withflowmeters having analog or pulse output.
It indicates alternatively instantaneous or totalized flow rate with alarm
output. Scaling, alarm setting and other parameters can be set througha key operation on front panel. Supplying loop power of 24V DC, it receives 2-wire transmitter and 3-wire pulse/analog signals. IR4600
saves panel space by its DIN48 ⫻ 96 compact housing and also eliminates troublesome wiring.

STANDARD SPECIFICATION● INPUT앳 Pulse input (receives pulse output sensor)

Over scale
If exceeding 6 digits, counter starts
from 0 automatically with alarm, byincrementing over scale frequency
endlessly.

앳 LED status lamps (Total 6 red and green LED lamps are on thefront panel)
Each lamp turns on at flow rate or totalized flow indication mode,
external input ON, flow rate or totalized flow over scale and alarm
activation.
