GE IC694MDL660CA-BC

Product Introduction

The IC694MDL660CA-BC is a 32-channel discrete input module for PACSystems RX3i, featuring 4 isolated groups of 8 channels, positive/negative logic per group, and 7 selectable input filter times (0.5–100 ms). It converts 24 VDC field signals (0–30 VDC range) to digital data, with 250 VAC continuous optical isolation (field to backplane) and 250 VAC group-to-group isolation. Each channel has a green LED for ON/OFF status, and the module uses a detachable terminal board (IC694TBB032/IC694TBS032). It supports hot-swap, integrates advanced diagnostics, and operates with RX3i CPUs (release 2.90+), delivering high-density, flexible input acquisition for industrial automation. The CA-BC variant denotes specific manufacturing and compliance standards, ensuring consistency with global industrial certifications.

Function Features

32 High-Density Input Channels: 4 isolated groups of 8 channels for large-scale signal monitoring with minimized chassis slots.
Dual Logic Configurability: Positive/Negative Logic per group to interface with PNP/NPN sensors and diverse industrial wiring.
7 Selectable Filter Times: 0.5–100 ms filters eliminate noise/debounce from mechanical switches or high-speed sensors.
Strong Isolation Protection: 250 VAC continuous isolation (field to backplane/group to group) blocks noise and ground loops, ensuring signal integrity.
Individual Channel LEDs: Green indicators enable instant visual verification and troubleshooting of each input’s status.
Grouped Common Wiring: 4 dedicated commons simplify wiring, reduce cross-group interference, and speed up fault isolation.
Hot-Swap Capability: Replace modules without chassis power-down to minimize production downtime.
Wide Voltage Tolerance: 0–30 VDC range accommodates industrial voltage fluctuations and transient spikes.
Low Input Current: 7 mA per channel reduces power draw and extends field device lifespan.
Advanced Diagnostics: Real-time module health monitoring and input status reporting via RX3i CPU for predictive maintenance.

Application Scenarios

Manufacturing Automation: Monitors proximity switches, limit switches, and pushbuttons in automotive assembly, semiconductor fabrication, and packaging lines, using 32 channels for high-density machine status tracking and filter times to ignore mechanical bounce.
Process Control: Captures valve positions, pump run signals, and safety interlocks in oil/gas, chemical, and water treatment plants, leveraging isolation to resist harsh industrial noise and grouped commons for segmented system wiring.
Power Generation: Monitors circuit breakers, transformer taps, and motor starters in utilities, with selectable filters for real-time grid protection and control.
Building & Infrastructure: Integrates access control, fire alarms, and HVAC status in smart buildings, using dual logic to interface with mixed equipment and grouped commons for simplified maintenance.
Marine & Offshore: Supports shipboard monitoring (tank levels, door interlocks) with Zone 2/ATEX C1D2 approvals and robust isolation for marine electrical noise.
Material Handling: Tracks conveyor sensors, pallet detectors, and elevator interlocks in warehouses, using filter times to handle high-speed sensor signals and dual logic for mixed equipment compatibility.
