GasGard® XL Controller
Monitor up to eight remote gas sensors with the highly accurate wall-mounted GasGard XL Controller. The controller's large, multi-language LCD display provides real-time readings, offers full-system diagnosis and shows intuitive icons. Housed in durable, fire-retardant ABS plastic, the controller is suitable for a variety of chemical, industrial and waste water environments. The sensor also features a buzzer that sounds up to 85 dB.
9010/9020 LCD
Advanced design and innovative features make the 9010 and 9020 Controllers the top choice for gas-warning systems, monitoring up to 20 channels. The 9010 Controller operates with one independent sensor, while the 9020 operates with two independent sensors per control module. Each module comes with an independent AC/DC power supply for increased system reliability. Both units feature full internal diagnostics, which minimize false alarms and unexpected down time. The controllers can also power remote sensors, while the large four-digit LCD and LED provide such crucial information as gas concentration, alarm status and more. A convenient RS-485 serial interface offers handy printer connection to make a record of data, while a customized transmission protocol Modbus RTU can record serial bus data transmission such as system configuration, gas concentration, alarm and failure events. The LCD version has approvals for FM (North America) and CCCF (China) whereas the newest 9010/9020 SIL controller is ATEX and SIL 2 certified.

MC600 Multi-Channel Controller
The MC600 is a microprocessor-based multi-channel controller that provides six channels of continuous gas detection. It can be configured as either a local gas detection system, or it can be networked to provide a large plant-wide distributed safety system. It is compatible with our hydrocarbon sensors, H2S sensors, as well as our S4000CH, S4100C, S4000TH, S4100T, IR400, IR5500, IR700, TS4000H, Observer, and Surveyor gas detectors.
