x Input Point Operation Type Single channel Use as single channel.
Single
Dual channel Use as a dual channel equivalent. This setting should be used only with
SmartGuard controllers.

x Safety Input Error Latch Time 0…65,530 ms
(in 10 ms increments) Safety input errors are latched for this time so that they can be read by the
controller and are not missed if they clear themselves too quickly. One value for all
channels. 1000
Low Engineering -30000…30000 Scaling value for inputs 0
High Engineering -30000…30000 Scaling value for inputs 10,000

x Tachometer Dual Low
Diagnostic ON/OFF Diagnostic that indicates if both channels are low.
Channels 0 and 1 share the same value and channels 2 and 3 share the same value. Off
Tachometer Trigger Falling edge (NPN) Non-inverted input signal. Falling edge
Rising edge (PNP) Inverted input signal.
Tachometer Off Level 0…23V
(in 1 V increments) Off-level for the Tachometer mode input signal. 5V
Tachometer On Level 1…24V
(in 1 V increments) On-level for the Tachometer mode input signal. 11V
Sensor Power Mode External Sensors are getting their power from a separate power supply. Module
x Module Sensors are getting their power from the module (recommended).
Alarm Enable Disable Enable or disable alarms.
We recommend disabling this feature when using the module in a GuardLogix
system (evaluate alarms using the application program). Enable this feature when
using the module in a SmartGuard system.

High High - Low Low
Deadband 0…32767 Deadband on the High High and Low Low alarms. 0
High Alarm -32768…32767 High alarm trip point. 332767
Low Alarm -32768…32767 Low alarm trip point. 0
High - Low Deadband 0…32767 Deadband on the High and Low alarms. 0
x Discrepancy Time 0…65,530
(in 10 ms increments) Time period during which the channel values may be discrepant before an error is
reported. 100 ms
x Discrepancy Deadband 0…32767 Tolerance range between channels in dual-channel mode (in engineering units) 0
x Channel Offset -32768…32767 Offset value for dual channel mode only (in engineering units). 0
