Chapter 13 Relay Output Channel
13.1 Features
13.1.1 First Channel Installed
The first Relay Output channel installed in an instrument supple-
ments the standard four limits (Limit 1, Limit 2, Limit 3 and Limit
4) . Its four, dry contact relay outputs will mirror the Limit Outputs
pins of the System connector.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 01-04.
13.1.2 Second Channel Installed
The second Relay Output channel installed in an instrument adds
another four limits to the instrument (Limit 5, Limit 6, Limit 7 and
Limit 8). Its relay outputs show the status of these limits.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 05-08.
13.1.3 Third Channel Installed
The third Relay Output channel installed in an instrument adds
another four limits to the instrument (Limit 9, Limit 10, Limit 11 and
Limit 12). Its relay outputs show the status of these limits.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 09-12.
13.1.4 Fourth Channel Installed
The fourth Relay Output channel installed in an instrument adds
another four limits to the instrument (Limit 13, Limit 14, Limit 15
and Limit 16). Its relay outputs show the status of these limits.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 13-16.
13.2 Wiring
The pin-out for the Relay Output channel’s 12-pin connector is
shown in the following table.

A SensoCode program running on a Mathematics Virtual
Channel may override the default behavior of the relay out-
puts. Consult the Customer Information Sheet included with
your instrument for details.
