EEC

Introduction

The EEC control board mainly includes the following functional modules: PID control module, electro-hydraulic servo control module, excitation source module, LVDT module, Resolver module, pressure sensor module, PXI signal acquisition, power module, external interface, etc. After systematic analysis the EEC board is in the form of 6U cPCI, using a carrier+daughter card mode, which is compatible with all EEC control board requirements.

We defined our EEC control board JMAS-CPCI2023, it is a high-performance, C-programmable single board computer that offers built-in digital and analog I/O combined with Ethernet connectivity in a compact design. The JMAS-CPCI2023 is ideal for both discrete and process control applications.

The microprocessor operating at up to 44.2 MHz provides fast data processing with 10/100Base-T Ethernet connectivity. Serial flash options support a full directory file structures to maximize remote access control and programmability. The I/O can be expanded with JMAS-CPCI2023PIN peripheral cards.

Features

• Microprocessor operating at 29.4 MHz or 44.2 MHz.

• Dual-entry IDC through-hole I/O header sockets allow header mounting on either side of the JMAS-CPCI2023 board.

• Industry-standard friction-lock connectors for power-supply wiring harness.

• 512K static RAM and 512K flash memory standard.

• 36 digital I/O: 16 protected digital inputs, 4 high-current digital outputs software configurable as sinking or sourcing, and 16 I/O individually software-configurable as inputs or sinking outputs.

• 12 analog channels: eight 11-bit A/D converter inputs, four 12-bit D/A converter 0–10 V or ±10 V buffered outputs.

• One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10/100Base-T Ethernet protocol.

• Up to 5 serial ports

Three serial ports (2 RS-232 or 1 RS-232 with RTS/CTS, 1 RS-485 or RS-232).

Two expansion ports multiplexed from one serial port.

One serial port dedicated to programming/debugging.

• Provision to install optional SF1000 serial flash, other memory options have provision for removable memory cards.
