5.2 Digital output
The digital output circuitry consists of an opto-isolated, solid-state relay for switching power
to external loads.
Each digital output circuit has a continuous current rating of 120 mA maximum and a max-
imum power dissipation rating of 180 mW. While providing 10 mA of load current, the
MOSFET on-state resistance is typically 21. The relay's maximum response frequency is 500
Hz.

5.2.1 Surge protection for digital output circuitry
When driving an inductive load (e.g., a relay coil), always use a C/R snubber or clamping
diode in parallel with the load to suppress large spikes.
