•Specifications are subject to change without prior notice for product improvement purposes.
*1 When Eco mode is set to rESP or ALL, the response time is doubled.
*2 For dual output types, the threshold value/timer and Light ON/Dark ON can be set individually for output 1 and output 2. Additionally,ASC is only available for output 1.
*3 No. of connectable units when used stand-alone or as the master unit: 2 to 3 units. Please use a load current of 50 mA or less for 4 to 8 units, and 20 mA or less for 9 to 16 units.
*4 Teaching mode from external input is a mode executed in advance by the main unit (default: 2-point teaching).
*5 The counter function is a function only for the dual output type, as counter reset input is not equipped to single output types.
*6 No. of connectable units when used stand-alone or as the master unit: 2 to 3 units. Keep at -25 to +50°C for 4 to 8 units, and -25 to +45℃ for 9 to 16 units.
