Conventional Multichannel Gas Monitoring Panel RK-220

The RK-220 Conventional Multichannel Gas Monitoring Panel is a robust and reliable solution designed for continuous gas monitoring and alarm systems in various industrial applications. Its fail-safe operational design ensures safety in environments such as refineries, sewage plants, fertilizers plants, stack monitoring, and more. The panel features a modular design with individual displays for each transmitter, making it easily expandable and simple to maintain. The user-friendly interface allows for easy customization of gas range, resolution, control actions, and latch facilities, all password-protected for security. The panel supports individual alarm relays for each gas transmitter, with options for isolated 4-20mA outputs and RS-485 communication using Modbus RTU protocol for integration with DCS/PLC systems. Compliance with the IEC-60945 standard for marine applications attests to its reliability in demanding environments. The panel offers precise gas concentration measurement with a high level of accuracy (± 0.1% of full-scale value). Its electrical specifications include flexible or armored shielded cables for gas transmitters and various output options such as relay contacts and isolated retransmission outputs.
