GE IS215UCVFH2A
Product Introduction
The GE IS215UCVFH2A is a high-channel-density VME digital I/O module belonging to GE’s Mark VI Speedtronic series, specifically engineered for medium-to-large industrial control systems requiring reliable discrete signal acquisition and multi-actuator control. As a core front-end and execution component in Mark VI-based architectures, it collects digital status data from field devices (such as limit switches, proximity sensors, and safety interlocks) and outputs relay control signals to mid-power actuators (like solenoid valves, motor contactors, and indicator panels), transmitting data to/from the main controller via the VME backplane and IONet network—ensuring seamless interaction between the control system and distributed field equipment.
Equipped with 16 configurable digital input channels and 16 relay output channels, the GE IS215UCVFH2A integrates advanced signal conditioning, galvanic isolation, and high-reliability relay driving in a standard VME 6U form factor. Its input channels support both sinking and sourcing 24V DC signals, adapting to diverse sensor wiring configurations, while the output channels use industrial-grade electromechanical relays with 3A per-channel current capacity—suitable for direct control of common industrial actuators. In practical applications, the GE IS215UCVFH2A acts as a “distributed control hub” of the Mark VI system, enabling centralized monitoring and control of multiple equipment clusters—balancing channel density, operational reliability, and system scalability for mid-to-large control scenarios.
Core Advantages and Technical Highlights
High-Channel-Density Integration
The GE IS215UCVFH2A features 32-channel (16 in + 16 out) integration within a single VME 6U slot, maximizing I/O density per chassis and reducing system footprint—critical for space-constrained control cabinets in power plants, refineries, or manufacturing facilities. This high-density design eliminates the need for multiple low-channel modules, simplifying system architecture and reducing wiring complexity. Each input channel can be independently configured via GE’s Proficy Machine Edition software (no hardware jumpers required), allowing on-site adjustment to match sinking/sourcing sensors without module replacement. The 16 relay outputs offer a total module current capacity of 8A, supporting parallel control of multiple mid-power actuators while maintaining load balance.
Industrial-Grade Relay Reliability
The GE IS215UCVFH2A uses industrial-grade electromechanical relays with a mechanical life of over 100,000 operations and electrical life of 10,000 operations at full 3A load—ensuring long-term stable switching in harsh industrial environments. Each relay output is equipped with surge suppression diodes to protect against voltage transients caused by inductive loads (e.g., solenoid valves), preventing module damage and signal distortion. The relays also feature visible contact status indicators on the front panel, enabling quick visual verification of output state during maintenance—reducing troubleshooting time for field technicians.
Dual-Interface Communication
The GE IS215UCVFH2A integrates both Mark VI VME backplane and IONet 10Base2 (BNC) communication interfaces, enabling flexible data transmission in distributed control systems. The VME backplane ensures high-speed, deterministic communication with the local Mark VI controller, while the IONet interface allows remote data exchange with other I/O racks or upper-level monitoring systems—ideal for large-scale control architectures where equipment is geographically dispersed. The module supports auto-discovery by the Mark VI controller and IONet network, significantly reducing commissioning time and configuration errors. It also integrates with GE’s Proficy Machine Edition for unified channel mapping, status monitoring, and diagnostic logging.
Typical Application Scenarios
Power Plant Auxiliary System Control
In coal-fired power plant auxiliary systems (e.g., coal handling, ash removal), the GE IS215UCVFH2A serves as the core digital control module. Its 16 digital inputs connect to limit switches (conveyor belt position, hopper level), photoelectric sensors (coal flow detection), and emergency stop buttons. The 16 relay outputs control conveyor motor contactors, gate valves, vibratory feeders, and alarm lights. When the Mark VI controller receives a “start coal feeding” command, it sends signals via the VME backplane to the GE IS215UCVFH2A, which sequentially activates the vibratory feeder, verifies coal flow via input, then starts the main conveyor—ensuring safe and efficient coal supply to the boiler. The IONet interface transmits real-time status data to the central control room, enabling remote monitoring of the auxiliary system.
Automotive Assembly Line Control
In automotive body assembly lines, the GE IS215UCVFH2A controls a section of welding robots and material handling equipment. Its input channels connect to proximity sensors (vehicle body position), limit switches (robot arm home position), and safety light curtains. The output channels control welding gun solenoids, robot grippers, conveyor drives, and station status indicators. When a vehicle body enters the station (input triggered), the GE IS215UCVFH2A receives a command from the Mark VI controller to activate the robot gripper, position the welding gun, verify alignment via inputs, then initiate welding—ensuring precise and repeatable assembly operations. The module’s high channel density reduces the number of modules needed per station, simplifying line architecture and lowering maintenance costs.

Installation, Commissioning and Maintenance Instructions
Installation Preparation
Before installing the GE IS215UCVFH2A, power off the Mark VI VME chassis and ensure the workspace is ESD-protected (grounded mats/wristbands). Required tools include a Phillips screwdriver, multimeter, torque wrench (0.5 N·m), and wire crimping tool. Verify the chassis slot supports VME 6U standards and prepare an external +24V DC power supply for relays. Align the module’s edge connectors with the slot guides, insert firmly until seated, and secure with front-panel screws. For wiring, use 16AWG-22AWG shielded cables; connect input signals to terminal blocks 1-16, output relays to 17-32, external 24V DC to the power terminal, and IONet BNC cable to the dedicated port. Configure input modes (sinking/sourcing) and IONet parameters via Proficy Machine Edition before powering on the chassis and external relay power.
Maintenance Suggestions
Conduct monthly inspections of the GE IS215UCVFH2A to check LED statuses (Power, Fault, IONet Activity, Input/Output) and terminal block connections—focus on relay output terminals for loose wiring or corrosion. Test input channels quarterly using a 24V DC signal generator to verify status detection, and test output relays with a multimeter to confirm contact continuity. Clean the module’s ventilation slots quarterly with compressed air (≤0.5MPa). If a fault occurs, first check external 24V DC power, IONet cable continuity, and sensor/actuator wiring; use Proficy Machine Edition to view channel-specific diagnostic logs (e.g., relay short-circuit alarms). Replace with genuine GE spares (lead time 2-3 days) and reconfigure I/O parameters to match the original setup—restoring operation quickly.
