*1 Ensure the cable length is 30 m or less (20 m or less when IO-Link is used) for the M12 connector type.
*2 Analogue output response time is 5 ms additional and 63% response.
*3 IO-Link: SpecificationV1.1/COM3 (230.4 kbps) is supported.
*4 Less than 182 mA including load.
*5 The operating ambient temperatures for the adjacent number of cable type/M12 connector type units and the number of zero line type expansion units should be 55°C for 1 to 2 units, 50°C for 3 to 5 units, and 45°C for 6 to 8 units. 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.
