 ThermoCool™ PC/104 Environmental Fan IICompany Description:PRODUCT INFORMATIONThe ThermoCool™ PC/104 Environmental Fan Card II provides thermostat-controlled forced-air cooling together with environmental monitoring of temperature, humidity and pressure conditions to increase reliability of embedded PC/104 computer systems, particularly in enclosed applications. In a thermostatic function, the board’s two high efficiency, brushless fans turn on and off, responding to changing temperature conditions while conserving power and increasing product life when not in use. In a sealed enclosure, the board can reduce or eliminate the need for outside air exchange. Air is driven in a push-pull circular cooling pattern around the board and adjacent PC/104 modules. Each fan can alternatively be reversed (flipped over) to create a push-push or pull-pull movement of air. Besides providing thermal management, the Environmental Fan Card II integrates capacitive humidity and atmospheric pressure sensors, which can be used as alarm indicators of moisture and pressure changes within an enclosed PC/104 system. The board's humidity sensor measures from 1-99% relative humidity with instantaneous desaturation, and its pressure sensor delivers a highly accurate, linear voltage output directly proportional to applied pressure (0-29 PSI) - with precise span and offset calibration, as well as temperature compensation. Other features include an elapsed time counter, two Form C relays, two digital inputs, four or seven analog inputs, LED activity indicator, configuration jumpers, Windows® 9x/NT/2000/XP drivers and a software test utility to enable the module to control external devices and integrate into a variety of complex environmental management schemes. Also included is onboard EEPROM scratch memory to provide the board with a unique serial number (for system identification) and permanent storage for configuration or maintenance information. Its elapsed time recorder / real-time clock detects and records the total time with power on and the number of times the unit has been turned on and off (power cycles). It also incorporate 10bytes of user-configurable EEPROM memory. This is particular useful for time-of-use warranty, calibration, repair, and maintenance requirements. This product is available in two versions: Part number PRV-0509-06 includes all three sensors (temperature, pressure, humidity) for a complete environmental monitoring and control solution, while PRV-0509-07 comes with a temperature sensor only (no humidity or pressure). An optional cable set (PRV-0509-08) with an external digital temperature sensor is available for either board if remote fan management is desired. More Info Worldwide Headquarters:
