IS200VCRCH1B

Overview

The IS200VCRCH1B is an I/O Board from GE. It is part of GE's industrial automation product portfolio.

Application & Technical Notes

As an i/o board, the IS200VCRCH1B is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the IS200VCRCH1B, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications

Technical Specifications Unit Name: IS200VCRCH1B Manufacturer: GE Model Series: Mark VI IS200 Application Types: TMR, Simplex Mark VIe Compatible: No Referenced In: GEH-6721L Group: H Variation: 1 Revision: B Condition: New Surplus, Factory Package CONTACT INPUTS A contact input terminal board (TBCI) is wired for the first 24 dry contact inputs; a second terminal board is needed for inputs 25–48. The contacts are given dc power. The terminal board is linked to the VME rack housing the VCCC processor board by cables with molded plugs. For inputs monitoring crucial turbine variables, high-speed scanning and recording at 1 ms per second are available. Contact chatter and pulse widths down to 6 ms are reported by the sequence of events (SOE) recorder, together with all contact openings and closures with a temporal resolution of 1 ms. RELAY OUTPUTS Twelve plug-in magnetic relays are stored in TRLYH1B. Jumpers can be used to set up the first six relay circuits for either driving external solenoids or dry, Form-C contact outputs. For field solenoid power, a standard 125 V dc or 115 V ac source, as well as an optional 24 V dc source, can be offered with individual jumper selectable fuses and onboard suppression. The subsequent five relays (7–11) have separated Form-C contacts that are not powered. An isolated Form-C contact is used on output 12 for particular applications like ignition transformers. VCRC OPTION The VCRC board is functionally equivalent to the VCCC board, however, it only requires one VME slot because no daughter board is needed. The TBCI boards' contact inputs are received by two front panel connections, J33 and J44. Similar to VCCC, relay outputs on TRLY connect to the J3 and J4 ports on the VME rack. VCCC can be used in place of cable placement on the front panel if it is undesirable. INSTALLATION OF IS200VCRCH1B BOARD Turn off the processor rack for the VME I/O. To seat the edge connectors, slide in the VCCC board and push the top and bottom levers in with your hands. Tighten the captive screws on the front panel's top and bottom. Switch on the VME rack and look at the front-panel diagnostic lights. OPERATIONS OF IS200VCRCH1B BOARD • The input voltages in the VCCC are sampled at the frame rate for control functions and at 1 ms for SOE reporting after passing through optical isolators. The signals are delivered to the VCMI via the VME backplane. The controller receives them next from the VCMI. The processing of contact input is depicted in the following figure. The dry-contact inputs are powered by a floating 125 V dc (100 - 145 V dc) supply. • Filters on each input control surge and decrease high-frequency noise close to the signal exit. A 4 ms filter is used to filter out noise and contact bounce. With 125 V dc excitation, the ac voltage rejection (50/60 Hz) is 60 VRMS. • For TMR applications, plugs JR1, JS1, and JT1 provide contact input voltages to the three VME board racks R, S, and T. Each controller rack's VCMI board votes on the outcomes once the three VCCCs have analyzed the signals. Relay control signals and monitor feedback voltages are transmitted between VCCC and TRLY through cables. • The relay board is mounted with relay drivers, fuses, and jumpers. TRLY, DRLY, and SRLY are just a few of the different relay board kinds that can be driven. The failsafe features on the relay outputs allow the inputs to vote to de-energize the corresponding relays when a cable is unplugged. The relays de-energize likewise if communication with the connected VME board is lost. SPECIFICATIONS Part Number: IS200VCRCH1B Manufacturer: General Electric Series: Mark VI
