Key Highlights & Features

Product Description

The R457 series of indicators are designed with both the installer and operator in mind and cover a wide range of applications. R457 is an indicator in a full stainless steel IP66-rated housing with waterproof USB host, Ethernet connections and cable glands for load cell and accessory connections. The USB host on the front of the indicator can support a variety of USB devices including point of sale printer, keyboard or USB stick.

The Ethernet functionality includes an embedded web server to allow the operator remotely to monitor the instrument with any device with a web browser. For an example, you can view the current weight and status from your phone.  The R457 carries Rinstrum’s Lua based scripting engine which allows for a variety of Lua applications to be used.

• L401 General
• L404 Truck Weighing

The modular design allows for the installation to be commissioned with only the components required, saving on time and money. With upwards of 2 versions of firmware available the R457 indicator is an ideal indicator for dealers and distributors as it simplifies installer training and reduces stocking levels.

Flexibility is the key with its award winning modular accessory design.  Modules include additional serial options, input/outputs, analogue outputs, external buttons, Alibi (Data Storage Device) and AC option.

Superior housings - R457 (stainless steel full housing) rated to IP66

The housing is designed with extra attention to detail to increase their reliability in the field, thereby reducing unplanned downtime and servicing costs.  For example, the R457 uses a high impact polycarbonate lens to protect the LCD from knocks.

Simple setup - use the menu system directly via the alpha numeric keypad or the configuration utility View400 on a PC.

Operator friendly - large multi-segment display that uses logical prompts along with dedicated and programmable function keys.  Printing can be tailored with custom record, docket or reports printouts.  Primary display is 29mm (1.1”) and secondary display 18mm.

Rugged Load Cell Input - Designed to take 16x320 ohm load cells; providing flexibility and reducing the need for summing hardware, simplifying the installation and saving money.  The load cell input is protected with onboard transorbs to limit damage from external voltage surges.

Networking Capability - Support for Ethernet to improve integration into larger control systems

Web interface – Web interface to download weight transactions

Application Packages

L401

The L401 is a general-purpose indicator suitable for weigh bridges, general trade weighing, multiple indicator weighing systems and process control. The Scale Entry/Exist features make the L401 ideal for unmanned weigh bridges.

L404

The L404 is designed specifically for truck weighing. It allows for a range of operational scenarios all in one setup, from weigh-in/weigh-out to stored truck ids. The dedicated Truck ID button and Print button simplify the operator interface. Additionally, the alpha-numeric keypad allows for easy entry of tare weight and Truck IDs. With 9999 Truck IDs available it is suitable for applications with truck fleets of up to 9999.

Modules

The R457 flexibility is provided through its broad range of modules that are easy to configure and neatly connect into the rear of the indicator. 1 module slot of the R457 is equipped with M4223 Lua module as standard. There are 2 more module slots where an indicator can be equipped with only the features required for a given installation.

Ethernet (M4223) Standard

The R457 comes with M4223 Lua module as standard. This provides R457 Lua enabled functions such as Web servers, USB, Ethernet, etc.

The Ethernet Module provides 10/100 Base TX with auto negotiation (1 Raw bi-directional port and 10 Raw transmit only ports).

Robust Input/output Modules (M4301, M4311, M4321)

An R457 indicator can be equipped with up to 24 I/O. These I/O are electrically isolated, designed for direct connection into PLC’s and can drive low voltage actuators directly.

• Isolated high side (400mA current source) drivers are capable of driving low voltage actuators directly or can be connected directly with PLC controllers.
• Each module has 8 digital I/O ports which are limited to maximum input voltage of 30V and can drive up to 400mA.
• Direct connection between I/O points is supported.
• Inputs are isolated to resist against system noise.

Button Module (M4302)

The Button Module provides 4 voltage free inputs for use with switches or thumbwheels. The voltage free inputs eliminate the need to wire up complicate input driver circuits.

Isolated Communication Modules

Communication modules are in addition the built in RS232/RS485 ports on the R457 indicator.

• Fully isolated and recommended for application where there is a risk of lightening or surges or where additional communication ports are required.
• M4201 RS232/RS232, M4202 RS232/RS485, M4203 RS485/RS485

Precise Robust Analogue Output Module (M4401)

The analogue module provides a 4-20mA or 0-10V analogue output and two digital I/O.

• Isolated to resist against system noise and interference therefore reducing unnecessary callouts;
• Precise with a 400Hz (2.5msec) update rate and 1/65,000 resolution. The fast update and high D to A conversion rate give a smooth output curve which helps a PLC to see more realistic readings (2.5msec step)
• Scalable to suit the input on the PLC.
• Two digital I/O provided the same as the M4301

Data Storage Device Module (M4501)

• The Data Storage Module provides nonvolatile alibi memory storage (6M bytes) according to WELMEC 7.2 L. Compatible with later versions of software.

Accessories

Converter 0-10V/4-20mA Input (M4902)

Connects to the Load Cell Input on R400 series indicators for a voltage or current input. Useful where an indicator needs to take an input from load pins on a crane scale for example.  Suitable for pressure, displacement or strain transducers that output 4-20mA or 0-10V analogue signals.

rin-LINK

The magnetically coupled rin-LINK on the front panel provides a convenient temporary connection to a laptop - no need to access rear of the indicator.

• Transfer of setup and calibration information
• Download of software upgrades

Relay Modules (M4901 and M4906)

The relay modules, used in conjunction with an I/O module, provide 8 voltage free relay outputs rated to 250VAC and 8A, available in either 12 or 24V.

• DIN rail mountable.

Provides N/O (normally open) and N/C (normally closed) contacts for each output.
