Product Introduction

The GE IS200BICRH1A functions as the Base Isolation Control Relay (BICR) module within the Mark VIe control platform, providing galvanically isolated relay output interface for critical control applications. This module interfaces with the Mark VIe controller via ISBus communication and offers 8 isolated relay outputs, 4 isolated analog inputs, and 4 isolated digital inputs for safe, reliable control of field devices in turbine and generator applications.

The model number breaks down as: IS200 (Mark VIe platform), BICR (Base Isolation Control Relay), H1 (High-Isolation), A (Enhanced Configuration). The primary differentiator is the comprehensive isolation (2500 V AC) and relay output capability—the BICR provides complete galvanic isolation for relay outputs, protecting the control system from high-voltage transients and ground loops.

Key Technical Specifications

Key Selling Points & Differentiators

• Comprehensive Galvanic Isolation: 2500 V AC isolation across all I/O channels—protects the control system from high-voltage transients and eliminates ground loops.
• High-Power Relay Outputs: 8 Form C relays rated at 5 A at 250 V AC or 30 V DC—directly control field devices without external interposing relays.
• Combined I/O: 8 relay outputs, 4 analog inputs, and 4 digital inputs in a single module—complete isolated control interface.
• Flexible Analog Inputs: Configurable for 4-20 mA or 0-10 V—compatible with a wide range of isolated sensors and transmitters.
• Relay Health Monitoring: Diagnostic monitoring of relay contact wear and cycle count—enables predictive maintenance.
• Full Live Test Certification: Each unit undergoes a 36-hour burn-in with full isolation testing (2500 V AC for 1 minute), relay cycling verification, and ISBus communication testing. We log the MAC ID, calibration data, and diagnostic baselines for traceability.
• Direct Drop-In Replacement: Form-fit-function compatible with IS200BICRH1 and earlier BICR revisions. Existing wiring and terminal assignments remain unchanged.
• 90-Day Warranty: Includes technical support and cross-ship replacement within 24 hours if the module fails to provide isolated I/O, isolation fails, or diagnostics report false faults.

Frequently Asked Questions (FAQ)

Q1: What’s the difference between the IS200BICRH1A and the IS200BICHH1A?

The BICR has relay outputs (8 Form C relays) instead of solid-state digital outputs. The BICH has solid-state digital outputs. The BICR is for applications requiring high-power switching (up to 5 A). The BICH is for standard 24 V DC load switching (0.5 A). Both modules provide the same 2500 V AC isolation.

Q2: What types of loads can the BICR’s relays switch?

The BICR’s relays are rated at 5 A at 250 V AC or 5 A at 30 V DC (resistive). They can switch: (1) AC loads—motors, heaters, lighting, solenoids (with proper suppression), (2) DC loads—solenoids, contactors, indicator lights, (3) Small motor loads (check inrush current), (4) Control signals—interposing relays, PLC inputs. For inductive loads (motors, solenoids), use external suppression (RC snubbers for AC, diodes for DC) to protect relay contacts.

Q3: The BICR shows a relay health warning—what does that mean?

A relay health warning indicates that the relay has reached a high cycle count or has detected contact wear. The BICR monitors the number of relay operations (cycles) and estimates contact wear based on the load. Possible causes: (1) The relay has exceeded the recommended cycle count (typically 100,000 cycles at rated load), (2) The relay has been switching inductive loads without suppression (causing contact wear). Access the diagnostic data in ToolboxST to identify the specific relay and the estimated remaining life. Plan to replace the module or the relay when the remaining life is low. In our experience, relay health warnings provide 6-12 months of advance warning.

Q4: The BICR shows an isolation fault—what could be the cause?

An isolation fault indicates that the module has detected a breakdown in the isolation barrier. Possible causes: (1) A transient overvoltage has damaged the isolation components, (2) Moisture ingress has compromised the isolation, (3) A field wiring fault (e.g., short to high voltage) has damaged the isolation, (4) The isolation components have failed. Access the diagnostic data in ToolboxST to identify the specific condition. If the isolation fault is confirmed, the module should be replaced immediately because the safety isolation is compromised.

Q5: The BICR shows a signal quality warning on an analog input—what does that mean?

A signal quality warning indicates that the isolated analog signal is degraded—typically noisy, out of range, or intermittent. The BICR monitors signal characteristics after isolation. Possible causes: (1) Electrical noise on the field cable, (2) A sensor that is failing, (3) A loose or corroded connection, (4) The signal is out of range. Access the diagnostic data in ToolboxST to identify the specific condition. The warning is a heads-up—the module will still provide data, but its quality may be degraded.

Q6: Can the BICR’s relays be used for safety-critical applications?

The BICR’s relays are general-purpose control relays, not safety-rated (force-guided) relays. For safety-critical applications (e.g., emergency shutdown, personnel protection), use safety-rated relays with force-guided contacts. The BICR can be used to drive safety-rated relays (the BICR’s outputs provide the control signal to the safety relay). The isolation of the BICR provides protection for the control system.

Q7: What’s the typical lead time for the IS200BICRH1A, and do you recommend stocking spares?

The IS200BICRH1A is a moderately stocked module—we maintain 5-8 units in inventory. Standard lead time for orders of 1-5 units is 1-2 weeks due to the specialized isolation and relay testing. For critical relay output applications, we recommend stocking one spare BICR per site. If you have a fleet of 5+ turbines, a 20% spare ratio is standard practice.
