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

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.

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.

RediPANEL 800A Push Button Modules
Push button Board
The push button assembly used is Bulletin 800A with 24 VDC six chip LED
cluster lamps which have longer life than incandescent lamps. The LED
cluster is polarity sensitive and will be positioned with the plus (+) indicator
facing left when viewing the front of the module. It is NOT acceptable to
interchange LED and incandescent lamps in the Bulletin 800A assembly.
Interchanging lamps could result in intermittent connections, since the lamp
bases have slightly different dimensions and mating contacts will set over
time. The contacts will be operating at 24 VDC.
I/O Modules
A sinking input module is used to interface with the Bulletin 800A contacts.
Each contact will typically draw 8 mA when energized. Connection from the
input module to the pushbutton contacts is through one of the cables
described in Table 2 on the next page.
A sourcing output module is used to interface to the 800A push button
assembly lamps (LED’s). Each LED will typically require 18 mA when
illuminated. Connection from the output module to the LED’s is through one
of the cables described in Table 2 on the next page.
Interconnecting Cables
Two preassembled cables connect the push button assembly and I/O
modules: one cable will connect to the input module and one to the output
module. All connections to Bulletin 800A contacts and LED’s are sent
through these cables. See Table 2 on the next page.
For SLC systems, each end of the cable for the 32 point RediPANEL has a
40 pin connector which mates with a 40 pin receptacle on the RediPANEL.
The other end of the cable has a 40 pin connector which mates with a 40 pin
receptacle on the Bulletin 1746 module. One end of the cable on the 16 point
version has a 20 pin connector which mates with a 20 pin receptacle on the
Bulletin 800A panel assembly and the other end has an 18 position prewired
swing arm which mates with a Bulletin 1746 module.
For PLC systems each end of the cable for the 32 point RediPANEL has a 40
pin connector which mates with a 40 pin receptacle on the RediPANEL. The
other end of the cable has a 40 point prewired swing arm which mates with
the Bulletin 1771 module. One end of the cable on the 16 point version has a
20 pin connector which mates with a 20 pin receptacle on the RediPANEL
and the other end has a 21 point prewired swing arm which mates with a
Bulletin 1771 module.

The input and output cable connectors are identified on the printed circuit
board. It is important that the input and output module connectors are
connected correctly, since the output modules do not have reverse polarity
protection. Connecting the wrong cable and module could result in a short to
the power supply output terminals or a blown module fuse. Some of these
fuses are not field replaceable.

To connect wires to the power connection from the power source, follow
these easy steps (see Figures 5 and 6):
1. Remove the power connector from the receptacle.
2. Loosen left and right screws on the power connector and insert the wires
into the openings on the bottom of the power connector, being certain that
the correct polarity is observed between the power connection and the
power source.
3. Tighten the screws on the power connector and insert the power connector
into the receptacle.
To connect the preassembled cables between the RediPANEL and I/O
modules, follow these easy steps:
1. Remove the tie wrap from the back of the RediPANEL and place it over
the cable at a distance of 8” from the end.
2. Insert the proper cable (see Table 2 ) into the appropriate connection
terminal (input or output) and secure with locking tabs.
3. Be certain that the distance from the end of the cable to the tie wrap is
8”, then reinstall the tie wrap to the back of the RediPANEL. See Figure 7
below.

I/O Modules
RediPANEL modules communicate directly with the programmable
controller via cables to I/O modules. Programming the devices in the
modules is identical to programming devices hardwired to I/O racks. This
means that the RediPANEL modules are mapped directly into the I/O image
tables of the programmable controller through the I/O modules.
