*1 To use the zero line type, connect it to the FS-MC8N/P, NU Series.
*2 This counts as 2 outputs/2 inputs when connecting multiple units to the FS-MC8N/P, NU Series.
*3 5 ms is added to the analog output response time and the response is set to 63%.
*4 The ambient temperature to use varies depending on the number of adjacent cable type/M12 connector type units or depending on the number of expansion zero line type units added to the system. For 1 or 2 units, the temperature is 55°C 131°F. For 3 to 5 units, the temperature is 50°C 122°F. For 6 to 8 units, the temperature is 45°C 113°F. The prescribed values for the ambient temperature assume that the amplifier unit has been mounted on a DIN rail installed on a metal surface. Exercise special care when installing the product in an airtight space.
