More About
Sielco operates in two main technology domains: FM broadcasting infrastructure for radio stations and industrial remote control and telemetry systems that support Supervisory Control and Data Acquisition (SCADA) and automation scenarios in utilities, infrastructure, and manufacturing environments.
In the broadcast segment, Sielco provides FM transmitters, exciters, and related components categorized within broadcast transmission equipment, which are used by commercial, public, and community radio stations to deliver over-the-air FM services. Its product range typically covers low- to medium-power FM transmitters (broadcast infrastructure) suitable for local and regional coverage, along with exciters that handle RF signal generation and modulation. These systems are deployed in transmitter sites, often in combination with antenna systems, audio processors, and STL equipment, and are designed to integrate into existing broadcast chains via standard audio and RF interfaces.
The company also supplies studio-to-transmitter link and audio processing solutions (audio transport and processing), which sit between studio playout and the RF chain. These devices handle audio routing, equalization, and modulation pre-processing and can interoperate with conventional broadcast studio equipment over analog and digital audio connections. This positions Sielco within the broader broadcast technology marketplace alongside other FM-focused infrastructure vendors, with a focus on hardware deployed at transmission sites and in technical areas of radio facilities rather than consumer reception devices.
In industrial automation and remote control, Sielco offers remote terminal units, I/O modules, and communication gateways (industrial automation) that support monitoring and control of field equipment. These devices are used in SCADA architectures to connect sensors, actuators, and PLCs to supervisory systems. The hardware commonly supports serial and Ethernet interfaces and protocols used in industrial telemetry and data acquisition scenarios, enabling integration into control centers and engineering workstations. Communication options may include IP-based networking, licensed or unlicensed radio, and GSM or cellular modules (M2M/IoT connectivity), allowing deployment in distributed infrastructures such as water networks, energy distribution, and environmental monitoring sites.
Sielco’s tools and configuration environments (technical services) support setup of communication parameters, I/O mapping, and alarm handling, facilitating integration into existing control rooms and broadcast facilities. From a directory and taxonomy perspective, Sielco aligns with categories such as broadcast RF transmission equipment, radio studio and STL hardware, and industrial remote control and SCADA telemetry devices, serving engineering teams responsible for radio networks, utilities, and industrial process monitoring.
