6.1.1
Reliability Tests
The test results in Table 6.2 were gathered from a 1 sec ON/OFF test cycle. Please note that
the over current induced by in-rush greatly reduces the relay contacts service life. The rated life
for an inductive AC load such as a contactor or solenoid valve is 500,000 operations at 20VA.
6.1.2
Response Times
OFF times increase as the load current decreases.
For improved response times use a 'dummy' resistor, see Figure 6.2. If a response time of 0.2
msec or better is required when using 'light loads' use a 'dummy' resistor and ensure the signal
line has a current greater than 60mA/24V DC.
