Key Highlights & Features

Product Description

The TBOX converts 2 or 4 analogue load cells signals to a multichannel digital signal back to a controller.  Each load cell signal is available at the controller.  The TBOX is commonly used on multi-head machines to save on cabling all analogue channels back individually.  The digital signal uses a daisy chain cabling configuration further saving on cabling complexity.

The TBOX is fitted with M12 connectors to provide easy connectivity.  The M12 connection for the loadcells is a standard 5 pin connector and the M12 digital tail uses an 8-pin standard.  Rinstrum supplies 8 pin M12 T connectors for simple ring networking with RS485. RS232 version can be used for single point applications working back to a PC or PLC.

The TBOX is ideal for machine builders with multiheaded weighing elements and is available through a design consultation.

How do you setup a TBOX?

• A Rinstrum rinLINK provides a magnetically coupled optical link on the unit, for a convenient temporary connection to a laptop
• The serial connection allows for download of software upgrades
• Running the free Viewer program on the laptop gives easy access to the setup menu tree.

How do you cable multiple RS485 TBOX together?

• The serial connection on the TBOX uses 8 wires with an M12 connector.
• The RS485 digital connection can be connected in a ring configuration to reduce cabling using the T junction (MC8J1).
• Alternately a multi drop configuration can be used if preferred or if there are limitations with the PLC (MC8J2 junction is used to support the cabling).
• Rinstrum has a range of 8pin M12 connectors and cables.
