DS200DMCAG1A DS200DMCAG1AHC Interface Board

The GE DS200DMCAG1A DS200DMCAG1AHC manages signal routing between control and field devices. This board converts analog inputs into digital values for the main processor. Therefore, it acts as a translator for mixed signal types.

Product Overview

We built this interface board for applications requiring both analog and digital channels. Its hybrid design handles voltage, current, and discrete signals simultaneously. Moreover, this unit replaces earlier DMCAG models with identical footprint and pinout.

Signal Processing Path

The GE DS200DMCAG1A DS200DMCAG1AHC uses 12-bit ADCs for analog conversion. Its eight decoupling capacitors maintain clean power for sensitive measurement circuits. Additionally, each analog channel includes programmable gain amplifiers. You can set gain values through software without opening the cabinet.

Configuration Methods

Set channel modes using the onboard dip switch bank. Position one selects voltage or current for analog inputs. Positions two through four define the input range for each group. Therefore, you can mix different sensor types on the same board. Always cycle power after changing any switch settings.

Installation Procedure

Remove power from the rack before you insert this board. Align the GE DS200DMCAG1A DS200DMCAG1AHC with its card guides carefully. Push the board until you hear the ejector tabs click into place. Then tighten the top and bottom screws to secure the connection.

Field Wiring Tips

Use shielded cables for all analog input connections. Connect the shield drain wire only at the board end. For digital outputs, keep wire lengths under 30 meters. The GE DS200DMCAG1A DS200DMCAG1AHC provides relay contacts rated for 2 amps. Therefore, add external interposing relays for higher current loads.

Replacement Scenarios

Many facilities choose this board when upgrading from older DMCAG revisions. Its software-compatible design simplifies migration without code changes. Furthermore, the board works in both Mark V and retrofit applications.
