timing range:

1 HOUR

$232.01

Description of Function

Upon initial application of input voltage, the output is energized and time delay (t1) begins. Time Delay (t1) is adjustable as a percentage of the overall cycle time (t2). At the end of time delay (t1), the output is de-energized for the remainder of overall cycle (t2-t1). The sequence then repeats until input voltage is removed. If input voltage is removed and reapplied, the timing cycle will continue from where it left off when the input voltage was removed. A setting of 100% energizes the output continuously while a setting of 0% de-energizes the output continuously.

Description of Function

Product Overview

Features:

The PTA Series is a microprocessor-based Percentage Timer that delivers reliable and accurate timing for critical applications where a repeating ON time of a fixed length cycle must be adjustable. These products provide an economical way to deliver precise and reliable repeat cycle timing in all types of industrial environments. Typical applications include controls for irrigation, chemical feeding, electric heating and cooling, motors, and lubrication systems. Industry-standard panel cutout dimensions and mounting pattern Retains timing sequence in the event of power loss Time ranges: 15 seconds to one hour Onboard potentiometer for easy time delay adjustment LED indicates relay status Terminal block design makes wiring easier from top or bottom Robust pressure plate terminal block provides secure termination with bare wire or crimp terminals Memory and no memory options available

Enclosure Style:

Panel mount with supplied hardware

Operations

FUNCTION: PERCENTAGE Upon initial application of input voltage, the output is energized and time delay (t1) begins. Time Delay (t1) is adjustable as a percentage of the overall cycle time (t2). At the end of time delay (t1), the output is de-energized for the remainder of overall cycle (t2-t1). The sequence then repeats until input voltage is removed. If input voltage is removed and reapplied, the timing cycle will continue from where it left off when the input voltage was removed. A setting of 100% energizes the output continuously while a setting of 0% de-energizes the output continuously. FUNCTION: PERCENTAGE (NO MEMORY) Upon initial application of input voltage, the output is energized and time delay (t1) begins. Time Delay (t1) is adjustable as a percentage of the overall cycle time (t2). At the end of time delay (t1), the output is de-energized for the remainder of overall cycle (t2-t1). The sequence then repeats until input voltage is removed. If input voltage is removed and reapplied, the timing cycle will be reset. A setting of 100% energizes the output continuously while a setting of 0% de-energizes the output continuously.
