3binaryinputs 1output TRIAC ETS product family: Heating, A/C, Ventilation Product type: Valve Intended use Switching of electrothermal actuators Installation in flush box according to DIN49073 Connection with enclosed terminals Product characteristics Three binary inputs for potential-free contacts, usable as extension inputs for local operation Supply via bus, no additional power supply necessary Switching operation or PWM operation Actuators with characteristics normally open or normally closed can be controlled Overload-protected, short circuit-protected Protection against jamming valves Forced position Cyclical monitoring of the input signals can be parameterised PWM operation: electrothermal actuators only have the positions Open and Closed. In PWM operation, switch-on and switch-off during the drives cycle time achieves an almost constant behaviour.
