About the IS200TRLYH2FAA
Hardware Tips and Specifications
The IS200TRLYH2FAA is a GE Relay Output Terminal Board (TRLY) that was created to be part of the Mark VI Control System. The IS200TRLYH2FAA interfaces with a Discrete I/O PCB (VCCC or VCRC). This board can accept 28/125 VDC or 120 VAC operating voltages. It is normally used with a WPDF daughterboard. It has:
- a total of 12 fused solenoid driver relays (with WDPF)
- 12 dry circuit relays (without WDPF)
- TMR control type relays that are mechanical Form B
- Form B (NC) outputs instead of a Form A (NO) contact
- Two terminal strips with 24 terminals on them
- terminals are barrier-type
There are two male ribbon pin connectors that are on the left and right side of the card. On the topmost edge of the card, there are three female RS-232 ports. On the bottom two corners, there are two reinforced terminal holes that are factory drilled. There are two factory drilled holes in the top two corners as well. There are numerous capacitors and resistors on this board. There are a total of 36 relays on this card.
