Device option Description
Supervised output: For modules that output an unsynchronized signal and that
do not turn off when you press Signal Silence.
Supervised output (latched): For latched output modules that output an
unsynchronized signal and that do not turn off when you press Signal Silence.
Unlatch outputs: For output modules that manually unlatch latched outputs.
Latched output device types
Supervised Outputs (Latched) : For Class B latched output modules that output
an unsynchronized signal. Does not follow signal silence.
Continuous Non-Silenceable (Latched) : For Class B latched output modules that
output an unsynchronized signal. Does not follow signal silence.
Continuous Non-Silenceable Class A (Latched) — Cont NS ClA Latch: For Class A
latched output modules that output an unsynchronized signal. Does not follow
Signal Silence.
Supervised Outputs Class A (Latched): For Class A latched output modules that
output an unsynchronized signal. Does not follow Signal Silence.
Relay Non-Silenceable (Latched): For Class B relay devices functioning as latched
output devices. Does not follow signal silence.
Relay Non-Silence Normally Open (Latched): For relay devices functioning as
latched output devices that close when activated. Does not follow signal silence.
Relay Non-Silence Normally Closed (Latched): For relay devices functioning as
latched output devices that open when activated. Does not follow signal silence.
1. Table 24 on page 96 gives a full list of devices configurable as latched output devices.
2. The following output modules can be configured to unlatch latched outputs: SIGA-CT1, SIGA-CT2,
SIGA-MAB, SIGA-MCT2, SIGA-MM1, and SIGA-UM.
