The Adjustable Transmitter Model AT4201 is a hand held, loop powered, current transmitter. It is attractive and simple to operate, making it ideal for use as part of a product demo unit. Built rugged to endure normal abuse encountered while testing control equipment, the low cost design makes it a good choice for field service technicians to carry as standard equipment in their tool case.
The BOAC unit is a solid state device that charges the backup battery used in a 12 V DC alarm system that has an alarm strobe light and horn. The BOAC unit activates the alarm strobe light and horn automatically when there is a loss of 120 V AC power. Upon loss of 120 V AC power, there is a time delay of approximately 5 seconds when switching from the charging circuit to the battery powered alarm circuit. This delay prevents momentary power glitches from causing nuisance alarms. During an alarm with a loss of 120 V AC, the alarm strobe light and horn are powered by the battery. Battery power is conserved by operating the horn intermittently, on for 2 seconds, and then off for 2 seconds. An alarm contact closure across pins 3 and 10 with ...
The Flasher provides a simple means of achieving a 120 V AC alarm flash circuit, without the high cost of a stobelight. The most common application would be flashing an incandescent light bulb. The rate of flash is approximately 30 flashes per minute.
(2) The Intrinsically Safe Relay provides a safe and reliable method of load control when interfaced with a contact closure in a hazardous location. When the control switch input is closed between pins 1 and 8, the output relay becomes energized, and the LED is illuminated. When the control switch input is open, the output relay is de-energized, and the LED is turned off. UL listed apparatus provides intrinsically safe circuits for use in Class I, Groups A, B, C, D Class II, Groups E, F, G and Class III - Hazardous Locations
The PS100 is a compact, regulated, linear 24 V DC power supply, capable of supplying up to 100 mA of current. It operates from 120 V AC and has a solid state resettable fuse on its output. The 120 V AC input is transient protected by an MOV. The 24 V DC output is transient protected by a transient voltage suppressor diode. The PS100 plugs into a 12 pin base and has a lexan enclosure to allow fast installation and easy servicing.
