Typical discrete input wiring diagram
The flow computer can accept two pulse inputs from customer input
devices (reed switches, slot sensors, magnetic pickup, uncommitted
transistor outputs, etc.).
The pulse input device must be resistive or inductive in nature only, with a
maximum output of +15 V if one of the +5 Vdc pull-up modes is not
selected. The pulse inputs on the main board are at TB7 and are identified
in the following table.
