Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. “Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls” (Publication SGI-1.1) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will the Allen-Bradley Company be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, the Allen-Bradley Company cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Allen-Bradley Company with respect to use of information, circuits, equipment, or software described in this manual.

Bulletin 2705 RediPANEL 800A Push Button Modules

Description

Bulletin 2705 RediPANEL Modules with Bulletin 800A Push Buttons are fully assembled 16 and 32 point push button stations that operate with high density Allen-Bradley PLC and SLC I/O modules. The only wiring required is a pair of cables and power supply connections, which eliminates costly hardwiring and provides fast installation and start-up.

Unless otherwise indicated, the descriptions that follow apply to both push button stations and both I/O modules.

Standard stations include 16 or 32 normally open (N.O.) illuminated push buttons. LED’s are used for illumination. The industrial 800A version is suitable for NEMA 13 oil/dust tight industrial enviornments.

RediPANEL 800A Modules can also be ordered as custom models which consist of the RediPANEL front plate and all the necessary push button wiring connectors.

These custom Push Button stations can include any of the following Allen-Bradley Bulletin 800A devices:

D Momentary illuminated or non-illuminated push buttons D Flush or extended head operators D Two position non-illuminated selector switches

Bulletin 2705 RediPANEL 800A Push Button Modules

Features

Easy Installation

Each RediPANEL is supplied complete with preassembled push buttons and front plate. Separately ordered Bulletin 1492 wiring system cables plug directly between the I/O Modules and the RediPANEL adapter boards, eliminating hardwiring of individual devices. To install RediPANEL modules follow these easy steps:

1. Cut an opening in the panel approximately 5.9 in. (149 mm) high x 8.6 in. (218 mm) wide. See Figure 1.

2. Drill four 0.296” (7.52mm) dia. holes for the top and bottom mounting brackets. A template is provided with the module to assist in this operation.

3. Slide the module through the opening.

4. Apply the mounting brackets and tighten all the captive knurled thumbscrews, being certain gasket is in place. Figure 1 shows screw locations.

5. Connect the appropriate cables between the RediPANEL modules and the PLC or SLC I/O modules. See page 10.

6. Connect external 24VDC power supply to pull-apart screw terminals on the RediPANEL.

7. Connect green ground screw on the RediPANEL to the earth ground.

See pages 9 and 10 for detailed instructions on connecting power and I/O cables.

Clearance Considerations

RediPANEL 800A Modules mounted inside an enclosure must have adequate space for wire clearances. See Figure 2 for minimum recommended spacing.

Bulletin 2705 RediPANEL 800A Push Button Modules

Low System Cost

The RediPANEL reduces overall system cost by reducing wiring, engineering, installation, and maintenance. Connection to high density Allen-Bradley I/O modules is simple, easy, and cost effective.

Functional Requirements

Electrical Requirements and Power Supply

An external 24 VDC  10% power supply is used for this module. The power supply must be able to provide the current requirements for the Bulletin 800A assembly and the selected PLC or SLC input sinking and output sourcing modules.

The Bulletin 800A LED’s use the power supply to draw the source current from the output module and the contacts complete the circuit for the sink current to the input modules. See Table 1 below for current requirements.
