Universal Modular System
The 27 mm*) (1.063 in.) wide PR2 relay base range
is a modular system consisting of PR2-B... relay bases,
robust REL-IR... electromechanical industrial relays
with DPDT and 4PDT contacts, and a comprehensive
range of accessories. These include:
– Plug-in input/interference suppression modules
– Relay retaining bracket with labeling field and eject
function
– Labels
– Continuous jumpers
Depending on the application, complete coupling
relays can be created, which are optimized in terms of
cost and function.
Base Versions
The relay bases are available in three versions - the
flat 2/2 level PR2-BSC2 type with screw connections,
and the "logical" 1/3 level PR2-BSC3 with screw
connections and PR2-BSP3 with spring-cage
connections. The logical versions have coil and contact
connections that are located opposite one another and
thus meet the requirements of modern control cabinet
concepts with clear isolation of control signals and
load.
Robust, Cost-Effective Industrial Relays
Industrial relays are used in many sectors of industry
due to their robust structure, which has 2.6 mm
(0.102 in.) flat pins. The main features of the REL/IR...
series include the fully automated manufacture of
products in conjunction with the high degree of product
stability and global availability. The following versions
are available:
– With two 10 A 2PDT contacts
– With four 5 A 4PDT contacts
– In all popular AC and DC coil voltages
Considerably wider and more expensive miniature
contactors can thus be replaced cost-effectively in
many applications without adversely affecting machine
or system operation. All industrial relays have the
following standard features:
– Manual test key (AC coil = red key, DC coil = blue
key)
– Mechanical switch setting display
– LED status indicators
– Free-wheeling diode (only DC types)
– Power contacts with solid gold coating (only types
with 4PDT contacts)
*) Spring-cage version is 31 mm (1.220 in.) wide
