Trigger Signal Cat. Nos. 700-HT / -HS

Contact closure provides signal to timer. A low energy signal is generated by the 700-HT / -HS timing relay. For optimum reliability, use contacts designed for low energy switching (10V, 1 mA) (Bul. 800F-X__V, 800T-X__V). No external voltage should be connected to the contact signal.
