A-B 1756-LSP Module Rockwell GuardLogix Safety Partner

The Allen-Bradley 1756-LSP is a GuardLogix safety partner controller. 

It has 250 connections but it does not have any user memory for standard tasks. 

Its safety memory depends on the memory of the corresponding primary controller. 

Its main purpose is to provide a redundancy, a second channel that is isolated for the system's safety-related functions. 

This controller has current draws of 1200 mA at 5.1V DC and 14 mA at 24V DC. Its power dissipation

is 3.5 W and its thermal dissipation is 11.9 BTU/hr. 

The isolation voltage is a continuous 30V which is basic insulation that has been type-tested 

from RS-232 port-to-system at 720V DC for 60 seconds. 

Its operating temperature is from 0-60 ËšC and its non-operating temperature is from -40-85 

Deg. C. It also comes with a maximum surrounding air temperature of 60 Deg. C. 

and a non-condensing relative humidity of 5-95%. 

Its operating shock is 30 g, its non-operating shock is 50 g, and its operating vibration is 2 g at 10-500 Hz. 

The configuration of the 1756-LSP safety partner is dependent on the primary controller since it does not have 

its own key switch and communication port although it has an RS-232 port.

It comes with a battery for the clock and backup power. 

The controller also has LED status indicators allowing you to monitor its current state. 

The controller ships with a nonvolatile memory, a CompactFlash card to be exact. 

It measures 27 x 17 x 7 centimeters and weighs 0.7 lbs. 

The 1756-LSP safety partner is used for the 1756-L61S, 1756-L62S, and the 1756-L63S controllers. 

It should be installed in the slot to the right of the primary controller to satisfy SIL 3 requirements. 

It also has an open-type enclosure.

1756 ControlLogix Controllers

The ControlLogix® controller provides a scalable controller solution that is capable of addressing many I/O points. You

can place the ControlLogix controller into any slot of a ControlLogix I/O chassis, and install multiple controllers in the

same chassis.

ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over network links. The

ControlLogix 5580 controllers have an embedded Ethernet port for a direct connection to Ethernet-enabled devices and

networks, and also support communication interface modules in the local chassis. To provide communication for

ControlLogix 5570 or ControlLogix 5560 controllers, install the appropriate communication interface module into the

local chassis.

ControlLogix 5580 and ControlLogix 5570 controllers are available with a conformal coating. A conformal coating

provides a layer of protection against contaminants and humidity to help protect the assembly and extend product life in

harsh, corrosive environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.
