(ac) max., opto isolated, burst fire. With or

without contact suppression.

• Open collector, switched dc signal provides a

minimum turn-on voltage of 3VÎ(dc) into a

minimum 500 load; maximum on voltage not

greater than 32VÎ(dc) into an infinite load,

isolated.

• Electromechanical relay

, Form C, 5A @ 120/

240~ (ac), 6A @ 28VÎ(dc), 1/8 hp. @ 120V~ (ac)

or 125VA @ 120V~ (ac). With or without contact

suppression. Off-state output impedance with
