Manufacturer: ALLEN BRADLEY
Condition: New and Unused, Surplus.
Overview of Allen-Bradley 1734-IB8
The Allen-Bradley 1734-IB8 is a POINT I/O digital sinking input module featuring 8 discrete input channels. It operates with a nominal 24 V DC input voltage and accepts signals within a 10 to 28.8 V DC range. Designed for distributed I/O architectures, this compact module connects with any POINT I/O communication adapter and requires a Point I/O wiring base such as 1734-TB or 1734-TBS.
