Description
Product Name ：IC694MDL250 GE Input module
Product details:
GE IC694MDL250 is an isolated AC input module manufactured by General Electric for the PACSystem RX3i series. Below is the detailed overview including specifications, key advantages, precautions, and applications.
Product Overview
The IC694MDL250 is a 120 VAC Isolated Input Module that provides 16 isolated input channels. It interface the PACSystem RX3i system with field input devices such as pushbuttons, limit switches, and proximity sensors operating at 120 VAC. Because each channel is individually isolated, inputs can operate from separate power sources or phase legs without cross-interference.
Technical Specifications
| Parameter | Specification |
| Module Type | AC Isolated Input Module |
| System Compatibility | PACSystem RX3i |
| Number of Inputs | 16 (16 isolated groups, 1 point per group) |
| Nominal Voltage | 120 VAC |
| Input Voltage Range | 0 to 132 VAC (47 Hz to 63 Hz) |
| On-State Voltage | 70 to 132 VAC |
| Off-State Voltage | 0 to 20 VAC |
| On-State Current | 12 mA (typical at nominal voltage) |
| Off-State Current | 2.5 mA maximum |
| Input Filter Response Time | 30 ms (typical) |
| Internal Power Consumption | 125 mA at 5 VDC (from backplane) |
| Isolation | Channel-to-channel and channel-to-backplane isolation |
Key Advantages
- Individual Channel Isolation: Each of the 16 channels has its own isolated common, allowing inputs to operate across different AC phases or distinct power supplies.
- High Noise Immunity: AC input signals combined with individual isolation reduce the impact of electrical noise, ground loops, and transient surges in industrial environments.
- Optical Isolation: Protects sensitive RX3i CPU and backplane logic components from field-side voltage spikes.
- Diagnostic LEDs: Front-panel LED indicators display the ON/OFF state of each individual input point for quick maintenance and visual troubleshooting.
Precautions & Installation Guidelines
- Wiring & Phase Separation: Ensure proper insulation and wiring practices when connecting inputs from different power sources or different AC phases to prevent cross-wiring or short circuits.
- Power Down During Service: Always disconnect field power and backplane power before inserting or removing the module to avoid equipment damage or electrical shock.
- Filter Delay Awareness: Account for the ~30 ms input response/filter delay when programming time-critical control logic.
- Voltage Thresholds: Verify that field devices maintain an off-state voltage below 20 VAC to prevent false “ON” signals caused by line leakage current.
Applications
- Power Distribution Control: Monitoring signals sourced from multiple sub-panels or different phase lines.
- Industrial Automation: Interfacing with 120 VAC field switches, selector switches, and limit switches across large assembly lines.
- Motor Control Centers (MCC): Reading status feedback signals (auxiliary contacts, trip indicators) from separate motor starters.
- Facility Infrastructure: Monitoring HVAC equipment, lighting control relays, and pump stations operating on independent circuits.
