Carrier Cards

Tews' TVME220 is a 6U VMEbus carrier for up to four single-size or two double-size IndustryPack® (IP) modules, allowing to build up modular, flexible and cost-effective I/O solutions for all kinds of applications, like process control, medical systems, telecommunication and traffic control.

The TVME220 uses VME64x-compliant connectors to increases the quantity of rear I/O connections beyond that of standard VME. All of the 200 I/O lines from the four IP slots are available at the VME64x connectors P0 and P2. The I/O mapping is compliant to the ANSI/VITA 4.1-1996 standard.

Although the rear connectors are VME64x, the electrical interface is standard VME, so that nearly all CPU products still have full access to the IP modules mounted on the TVME220.

Status indicators for IP access, +5V and +/-12V are provided in the EMI shielded front panel.

A set of 16-position rotary switches allows easy configuration of VME short I/O and memory addresses. Interrupt routing from the IP slots to the VME IRQs can be done in two ways: programmable by software or selection of predefined sets by a rotary switch.

The IP-power lines are fuse-protected by self-healing fuses and RF-filtered. The operating temperature ranges between -40°C and +85°C.

Two transition modules, TVME001-TM-10 and TVME002-TM-10 are available for easy access to all IP I/O lines.
