3.4.2 High Speed and General Purpose Outputs
In-Sight 3400 and 5000 sensors feature two built-in, high-speed discrete outputs. The 1460
I/O Expansion Module provides access to these outputs while providing an additional eight
general-purpose discrete outputs that can be used to trigger remote events. The high-speed
outputs are passed through the I/O module without processing.
Opto-isolators are used to interface the high-speed and general purpose outputs on the
1460 I/O Expansion Module. Typically used to trigger the status of a load (such as a sole-
noid, motor or lamp), the load may be directly connected to these outputs. When the input is
active, it pulls the output up to the supplied voltage, activating the load (Figure 3-6).

DESCRIPTION
Voltage
60V maximum through external load.
Current
On >50mA, 2.0A max, Fuse protected.
NOTE: Must be derated at -33mA/C for surrounding air temperatures above 25°C.
Off <50mA
NOTE
The general purpose I/O signals are approximately 1ms slower in updating and are inverse
in polarity when compared to the high speed outputs. This delay must be considered when
trigger rates exceed the required processing time.
