Fig. 9 SSR DRIVE OUTPUT WIRING
It is a time proportioning output.
Logic level 0: Vout < 0.5 V DC.
Logic level 1: Maximum current = 20 mA.
- 14 V ± 20% @ 20 mA
- 24 V ± 20% @ 1 mA.
NOTE: This output is not isolated. A duble or reinforced
isolation between instrument output and power supply must
be assured by the external solid state relay.
