DIN rail actuator EK-HE1-TP

KNX bus device with actuator function (in combination with a KNX room temperature controller) or controller / actuator (with acquisition of the temperature value by a KNX sensor). For 2- and 4-pipe hydraulic distribution systems with 8 TRIAC outputs for ON/OFF control of electrothermal actuators or servomotors for zone valves. Mounting in distribution board on EN 60715 rail (4 modular units, each 18 mm). To be used in KNX installations for home and building automation. Power supply from the bus and auxiliary power supply 230 Vac 50/60 Hz Control of 2- and 4-pipe hydraulic distribution systems 8 TRIAC outputs for ON/OFF control of electrothermal actuators or servomotors for zone valves The EK-HE1-TP actuator / controller is an ekinex® KNX S-mode bus device for the control of electrothermal actuators and / or motors for zone valves installed on distribution manifolds of installations with radiant panels or radiators. The 8 output channels use TRIAC to ensure a noiseless command and a high number of cycles. The device may work in combination with NC (normally closed) or NO (normallly opened) actuators and may be used in installations with 2 or 4-pipe hydraulic distribution; in the latter application it is possible to interlock the outputs, completely closing the active valve before the opening of the coupled valve, avoiding the mix of heating and colling conveying fluids. The device is provided with a membrane keypad for manual control of the outputs and LED indicators for the diagnosis of the operation state and of alarms triggered by short-circuit of the outputs or power failure.
