* When all outputs are ON, +5 V = 300mA. When all outputs are OFF, +5 V = 200 mA.

External Power Supply

With nominal voltage of 24 Vdc re-quired to power the field side of the B882**

Terminal Connector

AS-8535-000

Reference Type

Mapped as 32 bits input

Reference Type

Mapped as 32 bits output

Output Type

BIN/BCD

** The external power supply must provide power to the field side loads and the field side electronics. The amperage sizing requirements of this supply have three components: 160 mA/group maximum (all channels ON), plus steady state load current of all outputs capable of being ON simultaneously, plus the inrush current of all outputs capable of being switched simultaneously.
