If the load inductance is over the controller specifications, the output may need a RC filter (snubber) or
diode to properly handle frequent relay switching operations.

Switching Inductive Loads

When using switching inductive loads, the use of RC networks (snubbers) for AC loads or diodes for DC loads is
recommended to prevent disrupting the microprocessor's operation. The suppressors also prolong the life of the
relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks or diodes assembled by the
user or purchased as complete assemblies.
For AC loads, choose R and C as follows:
R: 0.5 to 1

Ω

for each volt across the contact

C: 0.5 to 1

μ

F for each amp through closed contacts

Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.
3. RC networks are available from Precision Digital and should be applied to each relay contact switching an

inductive load. Part number: PDX6901.
