GE DS200ADMAH1A DS200ADMAH1AAA Analog Daughterboard

The GE DS200ADMAH1A DS200ADMAH1AAA digital analog daughterboard adds mixed-signal I/O to Mark V systems. This daughterboard plugs directly into compatible motherboards for expanded functionality. You will find this daughterboard on GE Mark V processor and communication boards. Its compact design adds analog capability without consuming extra rack slots.

Daughterboard Architecture

This digital analog board features four analog input channels with 16-bit resolution. Consequently, it reads precision sensor signals for control algorithms. The GE DS200ADMAH1A DS200ADMAH1AAA also includes four analog output channels. Moreover, a dedicated interface connects directly to the host motherboard. You can install this daughterboard without special tools or adapters.

Precision Analog and Output Drive

The unit includes a 16-bit ADC for high-resolution measurements. Therefore, it captures small sensor changes with excellent accuracy. This daughterboard replaces the DS200ADMAH1AAA version without any motherboard changes. Simply remove the old board and install this one. GE designed this daughterboard for direct plug-in installation. Hence, it mounts securely using standard board-to-board connectors.

Four PCB layers separate analog and digital signal paths effectively. Two connectors handle all host interface and field I/O signals. The GE DS200ADMAH1A DS200ADMAH1AAA includes a precision voltage reference for stable conversions. Accordingly, it maintains accuracy over temperature changes. This feature proves essential for turbine control applications.

Installation and Configuration Guide

You must align the 40-pin header carefully before pressing down. The daughterboard uses keyed connectors to prevent reverse insertion. The GE DS200ADMAH1A DS200ADMAH1AAA works with specific GE Mark V motherboard models. Always verify host board compatibility before installation. Proper seating ensures all pins make reliable contact.

The field I/O connects through a separate 20-pin header. Use shielded cable for analog wiring beyond 3 meters. The GE DS200ADMAH1A DS200ADMAH1AAA expands analog capability for Mark V systems. Installation requires no configuration or software changes. This daughterboard operates in non-condensing environments only.
