Main Functions

Multi‑transmitter supervision: It can directly supervise up to four H201Ti intelligent transmitters via isolated supervisory links, typically covering A‑phase, B‑phase, C‑phase and auxiliary transformer transmitters within one transformer bank.More products: www.plcva.com

GE HYDRAN 201Ci‑C Communications Controller

Central network gateway function: Acts as a dedicated communication interface. It aggregates data from a maximum of 128 H201Ti transmitters on the RS‑485 network, and converts all field device data to one single RS‑232 / USB host‑computer link; optional modem access supports remote data access.
Network management: Supports daisy‑chain networking with multiple H201Ci‑C or H201Ci‑1 units over RS‑485 LAN. It handles data polling, protocol conversion, signal isolation and communication error diagnosis for the whole DGA monitoring network.
Note: This unit has no local LED display, no alarm indicator lights and no analog output terminals. It focuses purely on communication routing, without on‑site human‑machine interaction or hard‑wired alarm output capability.plcva.com

GE HYDRAN 201Ci‑C Communications Controller

Oil‑filled transformer DGA online monitoring system: Deployed in power plants, high‑voltage substations, industrial power distribution stations. It collects dissolved fault‑gas data (H₂, CO, C₂H₂, C₂H₄) measured by H201Ti sensors installed on transformer oil valves.plcva.com
Multi‑transformer centralized data collection: For groups of power transformers, shunt reactors and other oil‑immersed high‑voltage equipment. It forwards gas‑concentration trend data, sensor status and fault events to SCADA, DCS or host monitoring software for transformer incipient‑fault diagnosis (overheating, partial discharge, arcing).plcva.com

GE HYDRAN 201Ci‑C Communications Controller

System networking expansion: Used to build large‑scale distributed Hydran 201i monitoring networks. It reduces host‑computer interface ports and wiring workload for multi‑device monitoring projects.
Applicable scenarios: Utility substations, power‑generation facilities, petrochemical and steel‑plant power rooms, renewable‑energy station transformer health‑management systems.
