Hardware Tips and Specifications

The DS200DCFBG1BJB is a large rectangular board with a large number of surface mounted components. These include seven 4-position DIP switch devices and twelve configurable jumpers.

Six DIP switches are located together on one side of the board. These are used to scale or change many different inputs.

For example, switch number 4 (SW4) is used to regulate the voltage applied to the VCO output bridge circuit.

The board also has a neon light to indicate a blown fuse in the 115 VAC line and two LEDs to indicate blown fuses in the +24 VDC line and -24 VDC line.

Several specific integrated circuits of note are provided on the substrate of this DS200DCFBG1BJB product.

These integrated circuits, like many of the individual hardware components available in the assembly of this DS200DCFBG1BJB product, are accompanied by their own set of factory-printed nomenclature.

Each circuit contributes to a specific DS200DCFBG1BJB board and to the more robust Mark V Series automatic driver assembly features.

The integrated circuits in this DS200DCFBG1BJB power board assembly include:

Voltage and current feedback VCO circuits

Motor voltage attenuation circuitry

AC line magnetism and zero crossing circuits

Contactor drive circuitry

Field/armature SCR ignition circuitry

As noted above, each of the previously named circuits in this DS200DCFBG1BJB printed circuit board assembly was created by applying its specific function

applied to the larger DS200DCFBG1BJB board and Mark V series automatic drive assembly.

The various circuits of this DS200DCFBG1BJB product often have critical applications for the SDCC and LDCC boards in the Mark V series.

Both of these General Electric printed circuit boards are also available today from our inventory of new and refurbished circuit board products.

Other DS200DCFBG1BJB board components include test points, I/O connectors (1PL-1 through 1PL-40. 2PL-1 through 2PL-9. 4PL-1 through 4PL-5 and 5PL-1 through 5PL-26).

as well as fuses, resistor networks and resistors, capacitors, transistors, heat sinks, transformers, and relays. The board has test points for checking voltage signals and fuses for protection.

The module can be used to energize output devices such as relay coils, solenoid-driven instruments, indicator lights, and other instruments.

It has no snubber circuits or internal protective fuses, however, the user can install external protection accordingly.

The module does not display output leakage currents because the contact outputs are open-circuit when not activated.

In addition, each output channel has a response time of 10 ms and is dedicated to open-to-closed and proximity-to-open contact switching.

The maximum switching frequency of each output contact is 20 cycles per minute when used with inductive loads. Each output channel is equipped with a separate channel status indicator to characterize the operating status of each channel.

This IC200MDL940 has a maximum backplane current consumption of 490mA and requires a rating of 0 to 125VDC,

5/24/125VDC and 0 to 265VAC (47 to 63Hz) nominal external power supplies with a nominal supply voltage of 120/240VAC.

The IC200MDL940 module is a VersaMax PLC relay output module manufactured by GE Fanuc. It is equipped with 16 output points.

The module has A-type contact outputs and is compatible for use in Class 1 Division 2 rated environments over a temperature range of 0 to 60 degrees Celsius.

It complies with different environmental and industrial standards, including CE and cULus standards. These individual points are isolated from each other.

The IC200MDL940 module is rated for 24 volts DC and 120 to 240 volts AC. It is rated at 2 amps.

The front of the module has a lock/unlock lever. Each point has an LED to indicate activity on that point.

When the CPU logic bit is set to 1. the contacts in the module are closed.

The GE Fanuc VersaMax IC200MDL940 module is powered through the backplane. Loads on the module should be powered through an external power supply.

An additional CPU is required to handle the logic operations of the module. The logic and frame ground isolation ratings for the user input module are 250 volts AC continuous, 1500 volts AC for time periods up to 60 seconds.

The output voltage drop is 0.3 V maximum. The IC200MDL940 module has a load current of 10 mA per point.

The relay used in the module is a fixed coil relay with a movable arm. The contact type is made of high quality silver alloy.

The PQM is ideal when continuous monitoring of three-phase networks is required.

It measures current, voltage, real and reactive power, energy consumption, energy cost, power factor and frequency.

With programmable thresholds and 4 configurable output relays, control functions are available for specific applications.

These functions include simple over/under current or voltage alarms, unbalance alarms, load-related load removal/reset, and capacitor control for power factor correction.

Four digital inputs can be used for status such as breaker position, energy exchange information, etc. for more complex control.

The PQM can be used as a data concentrator for the production plant PLC, integrating process, instrumentation and power requirements.

All monitoring and control parameters can be communicated via 2 RS485 communication ports using the ModBus protocol.

If direct interconnection to the PLC is required, any monitored variable can be output through one of four isolated analog outputs.

Isolated Analog Outputs. Process variables can be measured using the analog inputs. The RS232 communications port on the front panel can be connected to a personal computer for simultaneous access to information by other personnel.
