Allen-Bradley 1734-TOP Terminal base

Description

The POINT I/O™ family is modular and has I/O modules that are ideal for applications where flexibility and low cost of ownership are needed for successful control system design and operation. As a key element in the Rockwell Automation® Integrated Architecture® system, the comprehensive diagnostics and configurable features allow you to apply the POINT I/O modules easily to any automation system and reduce costs for engineering through standardization. The modules can be used in remote device panels, local control panels, and can be accessed from many locations including the Internet. The modules have just-what-youneed granularity with 1...8 points to reduce system cost and size.

 The POINT I/O family includes these features:

• Channel Level Diagnostics for quick troubleshooting
• Multiple termination options and flexibility to save money, cabinet space, and commissioning and troubleshooting time
• Safety I/O and non-safety I/O on the same bus
• DeviceLogix™ for local control and fast response time
• Self-configuring modules that simplify your design and your inventory

POINT I/O has four major components:

• I/O modules provide the field interface and system-interface circuitry
• Communication interface modules provide the network-interface circuitry
• Terminal base units provide the wiring and signal termination for field-side connections and system power for the backplane
• Power distribution modules provide the expandability of the POINT I/O system and the flexibility to mix various signal types

POINT I/O modules offer 1...8 points per module. The I/O modules are interfaced to a network through a communication interface, which includes a built-in power supply that converts incoming 24V DC power to 5V DC backplane power. Each type of communication interface (network adapter) supports a maximum of 13…17 I/O modules, with a maximum of 10 A field power. The I/O modules receive power from the power supply through the backplane. With an external power supply, you can expand a POINT I/O assembly up to a maximum of 63 I/O modules or 504 channels.

The POINT I/O system follows a No Tools design approach. The terminal base, removable terminal block (RTB), and I/O module are assembled as a system without tools.

The base (A) mounts onto the DIN rail and provides the backplane. The POINT I/O module (B) snaps into the base. The RTB (C) snaps into the base and provides the wiring and terminations for field-side connections, as well as system power for the backplane.
