Forward-Reverse Timer Relays
A forward-reverse timer relay is a two-output timer relay that runs a motor in the forward direction for a set time, holds it idle, then runs it in the reverse direction, and repeats this cycle. It is used to sequentially control the forward and reverse contactors in drives that operate by changing direction, such as industrial laundry washing and drying machines and drum machines. The category includes the Entes SSR-2X and the dual-setting Tense ERS-07 models; product data lists time ranges such as 1 second to 100 minutes and 0.1 seconds to 60 hours. Select the relay by the setting range of the forward and reverse run times and the pause time, whether these times can be set separately, supply voltage, and current of the output contacts. A forward-reverse timer relay runs the two direction outputs in sequence with a pause between them; it should not be confused with a flasher timer relay, which switches a single output on and off.
