7.4.8 Relay Output Wiring
Function blocks ROUT1 and ROUT2 are located on the I/O Expander board. They provide two single-pole,
double-throw relay outputs, as shown in Figure 7-17. Relay contact ratings are stated in Section 13.6 MPU
Controller Board Specifications.
The load connected to a closed contact should draw a current between the minimum and maximum contact ratings.
A resistive load is recommended. An inductive or capacitive load can cause high peak currents or contact arcing
which can pit or otherwise damage contacts. The arcing associated with an inductive load can be limited by
connecting a voltage transient suppressor, such as a 1N4005 diode, across the load.
