Functional Description

DS3820AIPA1A is an Analog I/O Module manufactured and designed by General Electric. It is a part of the Mark IV Series used in Speedtronic control systems. Analog I/O Modules support multiple input and output channels, allowing them to handle various analog signals simultaneously. Analog signals are susceptible to electrical noise and interference. To combat this, Analog I/O Modules include built-in filtering mechanisms.

Features

• Equipped with a female terminal port featuring two apertures. Includes thirteen male connection terminals. Twelve of these terminals contain twenty metal pins each, while the thirteenth, slightly smaller terminal, contains ten metal pins.
• Four male terminal ports made of white plastic, each housing two to four gold-colored metal pins.
• Features seven large black rectangular components, each with 26 metal tabs on the top. Secured with four metal fasteners positioned between the black rectangles. Includes multiple screws and a thin metal edge with two pre-drilled holes for anchoring during installation.
• Additional screws reinforce the edges of the circuit board for stability.

Operator Interface Features

• The display's ability to eliminate the need to enter the Mark IV panel to make adjustments and identify issues is a crucial feature. The panel front is used for the great majority of this work. This is significant in terms of reliability because a single mistake in the old control might trip the turbine. The majority of settings for Mark IV are made using the control constants panel. The operator will navigate to the control constants display and select the appropriate page if he has to modify the value for a pre-selected load. For entering the adjust mode, the CRT will label one of the unused switches. For a switch function that is identified by software, we refer to these switches as soft switches.
• The Mark IV will request the password when this soft switch is pressed (not everyone should be able to change control constants!). The operator makes the adjustment within a specific range by using the cursor and the increment or decrement switches after entering the correct quantity.
• Despite its seeming complexity, this procedure may be mastered in a matter of minutes. In reality, it is simpler than the more traditional approach of using jumper wires to connect digital voltmeters to the appropriate places, flipping pots with a tiny screwdriver, and converting volts to engineering units. The Mark IV's ability to easily record settings via the printer is another advantage.

FREQUENTLY ASKED QUESTIONS

What is DS3820AIPA1A?
It is an Analog I/O Module manufactured and designed by General Electric.

What type of connections does the module have?
One female terminal port with two apertures. Thirteen male connection terminals:
Twelve terminals with 20 metal pins each. One smaller terminal with 10 metal pins. Four white plastic male terminal ports, each containing 2 to 4 gold-colored metal pins.

Is adjusting Operator Interface control constants complicated?
Despite appearing complex, the adjustment process is intuitive and can be mastered in minutes. It is far simpler than older methods, which required Connecting jumper wires to digital voltmeters, Manually flipping potentiometers with a screwdriver, and Converting voltage readings into engineering units.
