^1 Be sure to mount the DIN rail mounting amplifier on a DIN rail (i.e. the unit should be mounted on the metal DIN plate itself). For additional amplifier unit installation, be sure to use the end unit (OP-26751). ^2 One main unit and nine expansion units (ten in total) can be additionally installed. For additional amplifier unit installation, each output current must be 20 mA or less. ^*3 If additional amplifier units are installed, the power supply voltage is 24 VDC.
