Product Link 151/201 Spare Inputs Caterpillar


Spare Inputs
`

The Product Link has four additional inputs that can be configured in order to monitor switches on the machine. The four digital inputs can be configured by using the Electronic Technician. The inputs can be configured to be normally open or normally grounded. There is a programmable delay time for actuation of these inputs. The Electronic Technician requires you to enter a value for this delay. These inputs can only be used by switches to ground. These inputs cannot be dependent on other machine parameters. Existing machine parameters can be monitored or additional switches can be added. The inputs are listed in the table below:
