Description

Description: The Allen-Bradley 1756-RM is a ControlLogix enhanced redundancy module. It is part of the Programmable Automation Controller (PAC) which is used to implement controller redundancy. It comes with One (1) LC Fiber optic single mode connector and module status LED such as PRI, COM and OK, indicating the health of the system redundancy as well as module operation.

Technical Specifications for 1756-RM

The Allen-Bradley 1756-RM is a ControlLogix Redundancy module. This module may only be used with the ControlLogix platform to enable controller redundancy. It manages connectivity of Two (2) identical controllers, installed in an identical rack of the same components and configuration. It provides redundancy system monitoring as well as module health via the embedded LED display such as PRI, COM and OK.

The 1756-RM comes with One (1) single mode LC fiber optic connector. It requires use of the 1756-RMCx redundancy cable to synchronize the operation of the redundant controller pair. This controller may be configured using the redundancy configuration tool for setting up the redundancy and Studio 5000 Logix designer for configuring the overall parameters of the module.

This module is compatible with 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 ControlLogix chassis, 1756-PA72, 1756-PA75, 1756-PB72, 1756-PB75 Standard Power supply and 1756-PA75R, 1756-PB75R, 1756-PSCA2 redundant power supply. It is a single slot module and may be installed to any available slot in the chassis. The redundant pair must have the same configuration as to the partner chassis.

The 1756-RM redundancy module has a current draw of 4 milliAmps at 1.2 Volts DC, 1.2 Amps at 5.1 Volts DC, and 120 milliAmps at 24 Volts DC. The unit mounts in a chassis and it can be fitted into any slot. The 1756-RM module has a power dissipation of 9 Watts along with thermal dissipation of 31 BTU per hour. This ControlLogix comes with open enclosure and it carries the T4 temperature code. In regard to physical characteristics of the module, it weighs around 0.29 kilograms or 0.64 pounds and it has small dimensions. The 1756-RM module has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and it can be stored within a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The unit is made in accordance with several industrial standards and it includes certifications from the CE, CSA, Ex, C-Tick, and c-UL-us standards.
