For controlling electrothermal actuators for AC 24...230 V in heating/cooling systems via 6 silent semiconductor outputs. Electronic protection of the outputs against short circuits and overloads. Rated current: 0.5 A per channel and group of 3 outputs. Max. inrush current (2 sec.): 3.5 A per channel and group of 3 outputs. Max. inrush current (2 min.): 0.9 A per channel and group of 3 outputs. Direct operation per channel for opening and closing the valve and activating direct operation. Red LED per channel to indicate valve open or closed and status of the control variable. Red error LED per channel to indicate overload/short circuit and power failure. Maintenance-free terminals for connecting and looping untreated conductors, solid, fine-stranded, and multi-stranded, 0.5 to 2.5 mm². 2 terminals per channel for connecting the electrothermal actuators. 2 terminals on the device for supplying the valve voltage AC 24 230 V. Operation of the electronics via bus voltage. Housing: plastic, color RAL 7035 (light gray), N-dimension. Rail-mounted device for installation on TH35 DIN EN 60715 mounting rails. Protection class: IP 20. Max. width 4 TE.
