<1> Setting jumper S3 for an external power supply makes the wire jumper between terminals H1, H2, and HC ineffective. Remove the wire jumper
and connect an external power supply that can supply terminals H1, H2, and HC continuously.
<2> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-2, ISO/EN
13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.

24 Vdc, 8 mA
Use the wire link between terminals SC and SN or between SC
and SP to select sinking or sourcing, and to select the power
supply.
24 Vdc, 150 mA (only when DI-A3 is not used)
Use the wire jumper between terminals SC and SN or between SC
and SP to select sinking or sourcing, and to select the power
supply.
24 Vdc, 8 mA
One or both open: Drive output disabled
Both closed: Normal operation
Internal impedance: 3.3 kΩ
Off time of at least 1 ms
Set the S3 jumper to select sinking or sourcing, and to select the
power supply.
