The model RC-200, is a microprocessor based fixed gas detection system designed to accept the inputs from remotely located oxygen, combustible or toxic detector transmitters. The system is designed to provide continuous round-the-clock monitoring for a variety of common atmospheric hazards. It utilizes a point to point writing architectures, whereby each detector alarm/shutdown device and remote system is individually wired to the control unit. This is best choice for small systems, typically less than 20 points, where the sensors are located in relative close proximity to the central control unit.
The system is designed for easy expansion by means of plug-in sensor module. Remote TX – 250 transmitters are available in non explosion proof or explosion proof versions. Both versions can be with or without digital readouts.
The system includes built-in digital readouts at the controller. Other standard features includes – two independently adjustable alarm set points per channel, bright LED alarm light indicators and relay contacts for fault, low and high alarm conditions, common and channel specific 4 – 20 mA analog outputs for communicating sensor data to other systems.
HNL’s Model RC-200 rack/panel mount control enclosure along with micro controller based digital control modules is designed to serve as a host control system for remote mount gas detection sensor transmitters. The single channel modular designed can be configured for any combination of gases. All control modules are plug in front panel accessible for easy maintenance and repair. A “Blank Plate” can be installed on any unused channel until that channel is needed at some future date.
The module RC-200 includes an integral and modular power supply, three digit indicator serves as both a power indicator and a direct reading display of the gas concentration. Alarm set points are software adjustable in 1 PPM / % increments, across the range of detection. The reset switch resets all alarm relays.
