AC Voltage Signal (100V AC L-L) Input via -/100V AC PTs (3-phase 3-wire)
1. Cut out a hole on the object on where we will intall the meter according to dimension of meter referred above.
2. Remove the buckle on the meter off.
3. Install the meter into the cut-out hole.
4. Buckle up and fixed the meter.
1. Function Overview
Three-phase AC Voltage
LCD display
RS485,Modbus-RTU protocol;(1 start bit,8 data bit,1 stop bit,no parity)
Baud Rate 2400/4800/9600/19200 bps etc.
1 channel passive relay,contact capacity 3A/30VDC,3A/250VAC,
Used for high,low,unbalance alarm etc.
DC4~20mA,( load <500Ω)
(note:Shielded wire is specially selected for the above signal input and output)
DI (Digital input): 2-channel dry contact digital input with built in power supply
DO (Digital output): 2-channel digital output with NO relay contact. Capacity: 3A/30VDC,3A/250VAC
