2. Do not connect more than 2 wires to any single terminal.
This wiring diagram can be used in applications with 50mV (magnetic pickup),
1.3V (TTL), and 4V (preamp level) thresholds. You must use RSLogix 5000 to
choose the appropriate threshhold level for your application.

1. The wiring example above shows a 12-24V dc standard prover connected to the
module. If you use a 5V dc standard prover, make sure the positive wire is connected to
the 5V terminal (e.g. Z0 5V dc).
