Overview

This interface module combines the functions of a power supply, a TEACH button, and an SPDT relay to economically
interface dc-operated sensors for ac applications. The interface accepts either a 24V ac or 115V ac power supply,
depending on the model. It uses a transformer to isolate the input power supply from the dc sensor. The transformer
output voltage is rectified and filtered to supply up to 100 milliamps to run dc sensors.

An integral TEACH button can be used to activate the
TEACH functions of a Banner Expert™ sensor. Remote
TEACH capability also is available on all models (refer to
hookup diagrams and sensor literature).

The SPDT relay is controlled via the relay coil input. A dc
sensor output (either sinking or sourcing, depending on
interface module model) can be tied to the relay coil input.
The module's amber LED is ON when the sensor output is
active. The module's green LED is used as a power
indicator.

For sensor supply voltage and current requirements, refer
to the chart.

Installing the PS24-1 or PS115-1 Power Supply

The module must be isolated from conductive surfaces. It may be installed in a user-supplied housing using the four slots
in the board’s corners, or it may be inserted into the supplied plastic housing.

When you use the supplied housing, either insert the two DIN clips into the grooves on the housing’s underside and add
the two end caps (shown), or install only the end caps and use the screw-holes in the end caps for mounting to a flat
surface. Screws are provided for attaching the end caps to the housing.
