| *1 When extended, the ambient usage temperature varies according to the following conditions. Be sure to mount units on a DIN rail (attached to a metal plate) and ensure that the output current is *2 When more than 8 units connected, be sure to use supply voltage 24 VDC Ripple (P-P) 10 % max. *3 To connect several units they must be mounted on a METAL DIN rail. Ensure that the output current is 20 mA max. With several units connected, the allowable ambient temperature range varies as follows: 1 to 2 units connected: -10 to +55 °C, 3 to 10 units connected: -10 to +50 °C, 11 to 16 units connected: -10 to +45 °C |
