Overview

Common Applications
Product Precautions
GE IS200VCRCH1B is the single-slot VCRC board used in Mark VI discrete I/O channels. It identifies connected terminal hardware over the 37-pin cable, scans contact data in synchronism with the rack and exchanges the resulting status and output commands with the VCMI communications path.
- Mark VI single-slot VME discrete I/O processor
- 1 ms contact-input sequence-of-events time stamp
- TBCI contact-input and TRLY relay-output interfaces
- Hardware and firmware identity packet to VCMI
The operating chain runs from Field contacts and relay loads → TBCI / TRLY terminal boards → IS200VCRCH1B I/O processing → VCMI and Mark VI controller data path; document each boundary and prove the intended final response before release.
Important Notice: Keep terminal-board pairing and redundancy assignment consistent with the controlled Mark VI I/O database.
GE IS200VCRCH1B Manuals & Downloads
GE IS200VCRCH1B Official Technical Reference Excerpt (PDF)GE IS200VCRCH1B Installation & Commissioning Guide (PDF)
The Official Technical Reference Excerpt contains the applicable Mark VI discrete-I/O architecture and VCRC hardware pages. The commissioning guide adds a controlled replacement sequence, channel tests and handover evidence.
Sequence-of-events monitoring
Time-stamps discrete contact transitions to 1 ms resolution.
Turbine auxiliary I/O
Acquires permissives, alarms and equipment status for Mark VI control logic.
Relay command distribution
Processes output commands routed to TRLY relay terminal boards.
Simplex or TMR channels
Fits the documented redundant or nonredundant Mark VI discrete-I/O architecture.
Apply these controls specifically to GE IS200VCRCH1B before isolation, replacement, reconnection, energization and final release.
1
Match GE IS200VCRCH1B to the controlled rack position and terminal-board combination.
2
Remove field and rack power and verify absence of voltage before disconnecting VME or 37-pin cables.
3
Use grounded ESD controls when handling the board outside the Mark VI cabinet.
4
Record TBCI and TRLY cable destinations before removal so input and relay banks are not crossed.
5
Inspect the terminal-board ID-wire path and cable pins before energization.
6
Restore the approved Toolbox I/O configuration instead of copying settings from another rack.
7
Check contact wetting sources and relay-load isolation before forcing any point.
8
After replacement, test point mapping, SOE time stamps, relay outputs and all associated permissives.
Technical notes
Record the attached TBCI and TRLY terminal-board identities, 37-pin cable assignments and simplex or TMR channel role before removal. Complete SOE timing, relay-output, terminal-ID and board-health checks after replacement.
FAQ View All FAQ
-
What is the Mark VI role of GE IS200VCRCH1B?It is the VCRC discrete I/O processor for contact inputs and relay outputs.
-
How many contact inputs can GE IS200VCRCH1B process?The documented arrangement uses two TBCI boards for 48 contact-input points.
-
How many relay outputs are associated with GE IS200VCRCH1B?Two TRLY terminal boards provide a 24-relay-output arrangement.
-
What is the event resolution of GE IS200VCRCH1B contact inputs?VCRC contact transitions are time-stamped to 1 ms for sequence-of-events monitoring.
-
Can GE IS200VCRCH1B be used in simplex and TMR systems?Yes. The Mark VI architecture lists VCRC/TBCI and TRLY arrangements for TMR or simplex I/O.
-
How does GE IS200VCRCH1B identify terminal boards?The board reads terminal-board identity through the ID wire carried in each 37-pin cable.
-
What configuration data should be preserved for GE IS200VCRCH1B?Retain the rack assignment, point map, contact logic, relay map, cable destinations and Toolbox I/O configuration.
-
Which checks complete GE IS200VCRCH1B commissioning?Prove terminal-board identity, every affected contact point, SOE time stamping, relay actuation and controller diagnostics.
