Precision Timing Module for High-Voltage Circuits
The GE IS200WROGH1A IS200WROGH1APR1 adds programmable delay functions to GE control systems. This daughter board belongs to the Mark VI series from General Electric. It plugs directly into a compatible host board. Therefore, it provides accurate timing for circuit breaker and contactor operations.
Compact Dimensions and Lightweight Construction
This daughter board measures 8 cm in width, 6 cm in height, and 1.5 cm in depth. The GE IS200WROGH1A IS200WROGH1APR1 weighs approximately 0.06 kg, which makes it extremely portable. Its small form factor fits into tight spaces on the host board. Consequently, you can install it without removing adjacent components.
Connector Layout and Component Configuration
The GE IS200WROGH1A IS200WROGH1APR1 features one 14-pin male header for host board connection. It also provides two test points for timing verification. This board contains one timing capacitor array and three comparator circuits. Additionally, it includes four transient suppression diodes for input protection.

Energy Storage and Timing Accuracy Performance
The GE IS200WROGH1A IS200WROGH1APR1 stores energy to maintain timing consistency. Its capacitor array provides selectable timing values from 50 ms to 30 seconds. This storage charges through a precision resistor network. As a result, the delay remains accurate even with supply voltage variations.
Role Within the Mark VI Speedtronic System
You will typically find the GE IS200WROGH1A IS200WROGH1APR1 mounted on a relay output board. It adds delay functions to contact outputs without using software timers. Moreover, this board supports both on-delay and off-delay configurations. Its 250V rating allows direct use with breaker trip and close circuits.
Installation and Configuration Guidelines
Use the GE IS200WROGH1A IS200WROGH1APR1 as a direct replacement for older WROG revisions. Always power down the host board before inserting this daughter card. The 14-pin header aligns with a single keying notch. This board uses jumper selections for timing range adjustments. Simply press it firmly into the mating connector until the latch engages.
