  • IMB – Interface Module Backplane

IMB – Interface technology for backplane mounting with system cable

The IMB system from TURCK is an easy to-install I/O solution for the cabinet. It offers a high packing density which cannot be achieved with DIN rail interfaces.

The 176 x 210 mm IMB backplane can host up to eight interface cards, resulting into 32 digital or 16 analog I/Os per backplane. The interface cards are connected to the PLC via assigned slots on the backplane and a standard network connection.

All cards are hotswappable and can be plugged and unplugged during operation. Power can be supplied redundantly; decoupling takes place on the IMB cards.

The backplane accommodates the entire connection level; galvanic as well as Ex separation of the I/O channels is achieved simply by plugging the interface cards in the corresponding slots.

This helps you to cut down engineering efforts for the entire interface level in the event of maintenance and future extension of the system. HART® transmissible analog cards and DTM parametrizable temperature measuring amplifiers simplify parametrization and enhance the operating comfort.

Our strengths - your advantages:

Compact design, many mounting options
The 176 x 210 mm IMB backplane can host up to eight interface cards, resulting into 32 digital or 16 analog I/Os per backplane. A standard cabinet equipped on both sides thus accommodates up to 1152 digital or 576 analog channels. The backplane is snapped on a DIN rail with an adapter acc. to DIN EN 60715 TH35. The adapter can be mounted in different ways, allowing the IMB system to be installed horizontally or vertically on the DIN rail. The backplanes can also be mounted side by side to accommodate several IMB systems.

Simple operation with FDT/DTM
HART® transmissible analog cards and DTM parametrizable temperature measuring amplifiers round-off the IMB solution and simplify parametrization. The IMB cards are easily and conveniently set up using free FDT/DTM-based engineering tools. This applies to simple parametrization, complex diagnostic functions as well as to commissioning. The IMB temperature measuring amplifi ers are parametrizable via jack plug and also HART® protocol.

Passive backplane
The backplane is a purely passive unit and is used as a patch panel for I/O solutions. There are no active components on it, because any failure of these would lead to a complete outage of the isolation level. Each individual interface card is also protected, ensuring the functionality of the isolation level, even if single channels may fail.

Premoulded system cables for connection to the control system
The IMB backplane is equipped with a standard system connection for connecting to the DCS system. The pin configuration of the analog and digital system connections is adapted to the connected control system. This therefore eliminates the need for special connection modules. You can use prefabricated and reasonably priced analog and digital system cables for the most common control systems. This means you not only benefit from the reduced stock requirement but also from the considerably reduced installation and maintenance required on the interface level.

Redundant power supply
The IMB can be supplied redundantly via two separate power units. The electronics on the cards ensures the separation of the power supply units. Two removable terminal blocks on the backplane are intended for power supply.

Hot-swappable cards
The IMB system not only operates with a high level of fail-safety and economy, it is also easy to handle: The backplane accommodates the entire connection level, and the I/O channels are galvanically separated when the interface cards are plugged in. The engineering required for the interface level is thus considerably reduced – during maintenance and with planned extension of the system. The intrinsically safe screw and cage-clamp terminals are easily accessible. The color-coded and spatially separated system connections effectively prevent connection errors and allow convenient hot swapping in the control cabinet.
