8.4.8 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 8-21. Relay contact ratings are stated in Section 14.6.
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.

8.4.9 Local Instrument Link Wiring
The Local Instrument Link (LIL) is a high performance digital data link that carries commands and responses
between user-selected stations. Each station must be identified by a unique link address. This address permits
commands and responses to be sent from one station to another specific station. Lower link addresses are 1 through
32. A Model 321 Expansion Satellite is used to add an upper link with addresses 33 through 64. In the Moore 353,
the Station address is entered as the ADDRESS parameter in the STATN function block. Specific instructions for
