UNS2882A 3BHE003855R0001 DCS module

Safety made simple and flexible The new Allen-Bradley Guardmaster® 440C-CR30 Safety Relay is a flexible, cost-effective and easy-to-use configurable safety relay ideal for applications requiring four to 10 safety circuits and control of up to five zones. The Guardmaster 440C-CR30 Safety Relay is configured through a simple process of selecting certified safety function blocks to rapidly build your applications. The Guardmaster 440C-CR30 safety relay is completely integrated with Allen-Bradley Logix controllers and can be configured and programmed in the Rockwell Software® Studio 5000® environment. This means you can create, control and monitor a safety system in the same software environment as their standard control, resulting in increased productivity and reduced commissioning time

Increase your uptime

 An optional Ethernet plug-in module allows the Guardmaster 440CCR30 to easily communicate diagnostic data to an Allen-Bradley CompactLogix™ or Micro800 controller. By leveraging the features of Connected Components Workbench software and the embedded communication capabilities of the Guardmaster 440C-CR30 Safety Relay, users can monitor, troubleshoot and modify their applications quickly and easily for increased uptime. Five status and 16 user configurable LEDs on the Guardmaster 440C-CR30 relay’s faceplate provide local diagnostics to further aid in status reporting and troubleshooting. Optimize panel space With 22 on-board safety I/O points, including six configurable I/O, the Guardmaster 440C-CR30 Safety Relay is a flexible solution for applications requiring multiple safety zones. Without increasing the footprint, the 440C-CR30 can also be expanded with two standard Micro800 plug-in modules to support 16 additional standard I/O points, saving valuable safety I/O points for your safety system.

Supported temperature sensors are: 

● Thermocouples – TC type J, K ● Resistive temperature detectors – RTD’s type Pt100, Pt1000, Ni100, Ni1000 Further, the module supports all common measurement techniques: For RTDs: ● Two wire sensor connection ● Three wire sensor connection ● Four wire sensor connection For Thermocouples: ● Internal cold junction compensation: The sensors are directly connected to the module I/O terminal. ● External cold junction compensation: An external isothermal block can be used. The temperature of the external junction is measured using channel 0. The configuration of the four input channels is done by software. Every channel can be used independently of the others.

The PCDx.W745 is a precision analogue input module for temperature measurement application. Linearization and each kind of compensation as well as conversion into °C, °F and K are carried out on this module. The module has four input channels, which can be configured individually
