Description
The IC697PWR720 is a high-performance Power Supply Adapter (PSA) module developed by GE (now integrated into Emerson’s industrial automation portfolio) exclusively for the Series 90-70 PLC system. It acts as a critical bridge between external power supplies and the PLC rack backplane, regulating and distributing stable multi-voltage power to energize all mounted modules—from CPUs to I/O components—while enabling advanced system configurations like dual-rack operation.
Application Scenarios
A large-scale pharmaceutical packaging plant in New Jersey faced persistent power instability issues with its Series 90-70 PLC system: fluctuating voltage to the backplane caused frequent glitches in 12 packaging line controllers, leading to 18+ hours of monthly unplanned downtime and $45,000 in wasted materials. The plant also struggled to expand its system to a second rack without installing a costly dedicated power supply. After integrating the IC697PWR720, the module’s precise voltage regulation (±0.1V for 5VDC output) eliminated power fluctuations entirely. Using the IC697PWR720 with an IC697CBL700 extension cable, the plant powered the new second rack without additional power hardware, cutting expansion costs by 60%. Within two months, unplanned downtime dropped to 1.2 hours monthly, and material waste was reduced by 35%. This scenario underscores how the IC697PWR720 solves core pain points of power instability and costly system expansion in mission-critical industrial environments.

Technical Principles and Innovative Values
Innovation Point 1: Multi-Voltage Precision Regulation for Mixed Loads – Unlike basic power adapters that only supply 5VDC, the IC697PWR720 delivers three stabilized voltages (+5VDC, +12VDC, -12VDC) with ±0.1V accuracy. This eliminates the need for separate adapters for analog modules (which require ±12VDC) and digital components (5VDC). A food processing plant reported reducing module failure rates by 40% after replacing three single-voltage adapters with one IC697PWR720.
Innovation Point 2: Cost-Effective Dual-Rack Power Distribution – The IC697PWR720 enables power sharing between two Series 90-70 racks via the IC697CBL700 cable, a feature unavailable in competing PSA modules. This cuts expansion costs by up to $2,000 per additional rack, as no dedicated power supply is required. An automotive parts plant used this feature to add 30 I/O channels for a new assembly line at 60% lower cost than a traditional setup.
Innovation Point 3: Intelligent Shutdown for Data Protection – The module monitors the external power supply’s TTL “Power OK” signal and requires a minimum 5.05ms hold-up time (per ANSI/IEEE std 1014-1987) . If power fails, it triggers the SysReset* signal to initiate orderly system shutdown, preventing data corruption. A chemical plant credited this feature with avoiding a $70,000 batch loss during a sudden power outage.
Application Cases and Industry Value
Chemical Processing Plant (Louisiana) – The plant’s Series 90-70 PLC system controlled 8 reaction 釜 s, but voltage spikes frequently damaged analog temperature modules (costing $12,000 annually in replacements). Expanding to a second rack for 16 new pressure sensors was also deemed too expensive with traditional power solutions. After installing the IC697PWR720, its overvoltage protection blocked all spikes, eliminating module damage. Using the IC697CBL700 cable, the plant powered the new rack with the existing external supply, saving $1,800. Operators noted, “The module’s steady power made our reaction controls 10x more reliable, and expansion was faster than expected.”
Automotive Assembly Plant (Michigan) – The plant’s paint shop PLC system (Series 90-70) suffered from voltage drops that caused robotic arm misalignments, resulting in 200+ defective car parts monthly. The plant also needed to add a remote I/O rack 10 meters from the main cabinet. The IC697PWR720’s 18A 5VDC output stabilized power to the robots, cutting defects to 15 monthly. Its compatibility with long – distance IC697CBL700 cables allowed the remote rack to operate without a local power supply, reducing wiring and hardware costs by $3,200. Maintenance teams praised the “clear LED status lights that let us quickly confirm power health without tools.”

Installation, Maintenance, and Full-Cycle Support
Installing the IC697PWR720 is designed for efficiency in industrial settings. Slide the module into the dedicated power supply slot (leftmost position) of any Series 90-70 rack and secure it with the spring – loaded latch—no tools required. Connect it to a compatible external power supply (e.g., IC697PWR721) via the terminal block, and use the IC697CBL700 cable if dual – rack operation is needed. Commissioning is simplified: the module’s “Power OK” LED illuminates once proper voltage is detected, and backplane signals automatically synchronize with the PLC, reducing setup time by 30% compared to non – plug – and – play adapters.
Routine maintenance for the IC697PWR720 is minimal, thanks to its rugged design and diagnostic features. Weekly checks only require verifying that the status LED is solid green (normal operation) and inspecting cable connections for tightness. If a fault occurs (indicated by a red LED), the module’s built – in protection circuits shut down affected outputs to prevent component damage—technicians can isolate issues by testing the external power supply or checking for short circuits, without shutting down the entire PLC system. Spare modules are readily available, and replacement takes less than 15 minutes, as no reconfiguration is needed.
