Ensure that all power is
switched off before
installing or maintaining
this product
Input/Output Allocation Tables
The following tables indicate; on a controller type basis, the functions of the inputs and outputs. Also shown are the digital inputs that are
derived by switching in a fixed value resistor across the input
