Analog Controller suits fixed-point gas monitoring.

Press Release Summary:

Appropriate for industrial and non-industrial applications, 2-channel Model 820 accepts one or two 4-20 mA input signals from any gas transmitter and displays reading on LED display. In addition to local interface, controller can be part of larger digital network using ModBus RTU protocol. It includes 5 programmable analog relays for alarm and fault conditions, and when alarm conditions are reached, unit can control alarms, fans, and horns as well as emit audible alarm.

Original Press Release:

New Analog Controller Ideal for a Wide Range of Fixed-Point Gas Monitoring Installations

PITTSBURGH - Industrial Scientific Corporation, the innovative leader in gas detection and monitoring equipment, is pleased to launch the low-cost 820 Controller as a flexible solution for fixed-point gas monitoring installations. Ideal for a wide range of applications, the 820 Controller can be used for its simple local monitoring and alarm capabilities as well as in more elaborate network setups.

Appropriate for both industrial and non-industrial applications, the two-channel analog controller can accept one or two 4-20 mA input signals from any gas transmitter and display the reading on the large LED display. The 820 Controller offers an easy-to-navigate user interface for configuration and control of every parameter including alarm values. In addition to the local interface, the 820 Controller can be part of a larger digital network using ModBus Remote Terminal Unit (RTU) protocol. This interface can facilitate sensor data sharing and remote operation of the 820 Controller through any ModBus RTU controller. A built-in signal pass-through feature also allows the values of the two analog input signals to be sent as two isolated 4-20 mA signals to other control devices such as a Programmable Logic Controller (PLC) or a Distributed Control System (DCS).

Five programmable analog relays are also featured for alarm and fault conditions. When alarm conditions are reached, the 820 Controller can control alarms, fans and horns as well as emit its own audible alarm along with LED and real-time display notifications.

Compatible with Industrial Scientific's iTrans and AirAware fixed-point gas detectors, the 820 Controller also includes programmable high and low alarm limits for each input channel, a real-time clock for time-stamping and date-stamping alarm records, separate alarm record tables for each input sensor, and a power LED that flashes when the supply power is above or below the acceptable range.

Industrial Scientific Corporation is a leading designer, manufacturer and marketer of gas monitoring instruments, systems and other technical products for the preservation of life and property. The company has headquarters in Oakdale, Pa. and regional offices throughout the world. To request a catalog, contact Industrial Scientific by phone at 1-800-338-3287 or 412-788-4353, or e-mail
