*1 The amplifier models indicated with “A” at the end of the model code are the upgraded version that provides compatibility with the DL series communication unit. Other models (without “A” at the end of
the model code) are not compatible with the DL series, but compatible with GT-H10/H10L/H22/H22L.
*2 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).
*3 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.
*4 If additional amplifier units are installed, the power supply voltage is 24 VDC.
