CONTACT SENSING INPUTS
Six contact sensing inputs provide external stimulus to initiate BE1-BPR actions. An external wetting
voltage is required for the contact sensing inputs. The nominal voltage level of the external dc source
must comply with the dc power supply input voltage ranges listed in Section 1, General Information,
Specifications. To enhance flexibility, the BE1-BPR uses wide range ac/dc power supplies that cover
several common control voltages. The contact sensing circuits are designed to respond to voltages at the
lower end of the control voltage range, while not overheating at the high end of the range.
The energizing level for the contact sensing inputs is jumper selectable for a minimum of 26 Vdc for 48
Vdc nominal sensing voltage, 69 Vdc for 125 Vdc nominal sensing voltage, or 138 Vdc for 250 Vdc
nominal sensing voltage.
