Rockwell Automation has broadened its Allen-Bradley relay

product line to include six new solid-state relays (SSRs). The

solid-state relay logic input control levels are compatible with

many industrial controllers available in today’s market such as

PLCs and temperature controllers. The switching design of the

solid-state relay uses no moving parts or contacts that can wear

out. This is one of the reasons they will perform in a variety of

harsh environments.

Long Life Expectancy

Solid-state relays use electronic instead of mechanical devices

for load switching while providing a life cycle expectancy of

approximately 100,000 energized hours or 11.4 years. This

reduces product replacement and downtime.

Low Maintenance

There are no moving parts or contacts to wear out or be affected by

vibration and shock. Maintenance dollars, parts replacement, and

downtime are reduced drastically, if not eliminated altogether.

Reduced Power Costs

The solid-state relay typically requires 25 times less power

than electromechanical relays and also generates less heat.

This means the panel can typically be smaller, reducing panel

space requirements.

Flexibility

Plug-in style SSRs (700-SA, SC, SF and SK) are compatible with

Allen-Bradley 700-HN sockets and retainer clips. In addition, the

700-SA SSR is compatible with the 700-HT1 multi-function,

multi-range timer module while the 700-SC SSR is compatible

with the new 700-AT1 or 700-AT2 timer modules. The flexibility

and compatibility with these relay accessories support a wide

range of applications, while reducing spare parts inventories.

Rockwell Automation is introducing a new and improved Allen-

Bradley 700-HC “Ice Cube” General Purpose Relay. This 4-pole plug-in

relay has been redesigned to meet your low energy switching

application needs. Along with the 700-HC, Allen-Bradley is offering a

new, space-saving 700-HP printed circuit board (PCB) “Pin“ style relay.

700-HC Series D

• Cost-reduced design

• Improved low-energy switching capability

• Increased the I

switching capability from 5 A … 7 A

• Same Allen-Bradley relay family appearance on faceplate

• Incorporated manual override lever (-3 option) with the existing

push-to-test button

• New 700-HC Series A, 2-pole, 10 A version is now available

with silver contacts

700-HP PCB “Pin” Style

• PCB or socket mountable

• 5 mm Pin spacing available in a 2-pole, 8 A design

700-A Plug and Play Modules

• Module mounted within sockets

• Available as surge suppression, timing and LED modules

• Modules compatible with 700-HN104 socket (for 700-HC relay)

• Modules compatible with 700-HN123 socket (for 700-HP relay)

• Modules compatible with 700-HN153 socket (for 700-HB relay)

Coil and Contact Suppression Sockets

• 700-HN104 (for 700-HC relay), 700-HN123 (for 700-HP relay)

• 12 A, 300V AC rating

• Able to insert optional plug and play 700-A modules

Terminal Block Relays

With Reliable Gold Plated Contacts

• Ensures corrosion will not form on the contact surface over time.

• Switches low energy loads reliably as low as 8V, 2.5 mA.

• Ideal for very low energy logic switching applications such as TTL

drive enables and low energy I/O Cards such as Allen-Bradley

1734, 1746, 1756, 1764, 1771, 1791 and 1792 modules.
