GE DS3820CI2A Current Isolator Card

Part Number DS3820CI2A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3820CI2A is a Current Isolator Card developed by General Electric under the Mark IV series. This is intended for use in gas and steam turbine systems that are controlled by the Speedtronic Mark IV TMR (triple modular redundant). The Mark IV was General Electric's first TMR system. WOC has reconditioned used and liquidated new never-used Mark IV boards and other components available. 

Your current part can also be repaired by our Isolation between the line voltage and control sides of a unit is provided by this sort of module. An external metal box and an inside circuit board hold all functional components of the Current Isolator Module. It contains a number of integrated circuits, including an isolation amplifier (S1270) that is supported secondarily by a tie connection to the board's surface. There's also a terminal strip with three screw mounts, a quick-connect mount for a power component, a ribbon connection, two male pin connectors (both vertical), and a ground stab-on connector. Transistors, potentiometers, resistors, capacitors, and diodes are present on the board. It's screwed to the back of the external box's surface. The module is a metal box with a hinged front panel on the outside. The bottom panel of this panel contains a hole for board cabling to depart. On the front of the device are many warnings, including a high-voltage alert. Before commencing any repair or installation work on this module, please read and follow all safety and handling precautions.

Compatibility 

ƒ Compatible with any Series 90-30 CPU except IC693CPU321 and IC693CPU340. Configuration size is limited for CPU311/313/331, as described on the next page. 

ƒ Requires release 8.0 CPU firmware. The latest Release 10 is recommended, if available for the particular CPU. 

ƒ Requires CIMPLICITY Machine Edition Logic Developer PLC version 3.0 plus the appropriate service pack or special (or a version later than 3.0). 

ƒ Not compatible with the VersaPro™, Control, or Logicmaster™ programming software. 

ƒ The Series 90-30 Hand-Held Programmer (IC693PRG300) cannot be used to configure this module. New Features The Series 90-30 DeviceNet Master Module allows a Series 90-30 PLC to send and receive I/O data from a DeviceNet network. 

Module features include: 

ƒ Support for all standard data rates (125K, 250K, 500K) 

ƒ Support for 255 bytes input data transfer and 255 bytes output data transfer per slave 

ƒ Support for 3972 bytes of input data transfer and 3972 bytes of output data transfer per master 

ƒ Support for two I/O connections per Slave - Typically one connection is used for Polled and the other is used for Strobe, Cyclic, or COS 

ƒ Support for Poll, Strobe, Cyclic and COS I/O Connections, Fragmented I/O and Explicit Messaging 

ƒ Support for Unconnected Message Manager (UCMM) with 1 proxy connection per slave device 

ƒ Support for configuration of the global scan rate 

ƒ Support for configuration of update rates for Poll and COS/Cyclic on a connection basis 

ƒ Support for PLC-application initiated explicit messaging via a COMMREQ 

ƒ Master can be configured to operate as a slave simultaneously with master operation 

ƒ Configurable fault behavior on loss of communication 

ƒ Reports loss or reestablishment of communication with slaves in PLC fault table (configurable) 

ƒ Support for 64 network device status bits (note: the bit for the master itself is always zero) 

ƒ Firmware update via service port on module
