User connections are made to a standard screw terminal strip.The rigid wiring system permits module insertion or removal without disturbing the wiring.
Terminal Numbering and Input Connections
The following diagram shows terminal numbering and input connections for the B807–132 module.
NOTE: Pins 1, 20, 21, and 40 have no internal connections.
NOTE: The module can operate from 47—63 Hz. However, its use with proximity switches is recommended only at 60 Hz nominal line frequency. Leakage current through switching devices connected to the module may cause a false on condition.
Input Current–to–Frequency Relationship
The following illustration is a plot of the input current versus frequency.
