Tantalus Utility Network™
The TC-1120/1120-RD and TC-1220/1220-RD is a family of two-way 900 MHz LAN smart meter communication
modules that are integrated into the Itron CENTRON® C2s family of electrical watthour meters. The CENTRON
C2s metrology unit sends a blurt message that conforms to the ANSI C12.19 PSEM protocol to the communication
module. The Tantalus LAN communication module delivers meter readings on request or on a programmed
schedule for Time-of-Use and interval data applications. The LAN communication module also reports power
outages and monitors power quality including voltage (plus sag/swell alarms) and momentary outages (blinks).
