The GE Fanuc Emerson IC697HSC700 is a high-performance 12-input High-Speed Counter module for the Series 90-70 PLC. It supports pulse frequencies up to 800 kHz and features 4 onboard outputs, providing precise motion control and flow measurement for complex industrial applications.
The IC697HSC700 functions as a specialized High-Speed Counter (HSC) module within the legacy GE Fanuc Series 90-70 ecosystem, now supported by Emerson Automation. This module actively interprets rapid pulse signals that standard I/O modules cannot track, making it an essential component for high-precision industrial tasks. Specifically, the hardware supports impressive frequency thresholds, reaching 200 kHz in Up/Down Quadrant modes and peaking at 800 kHz when operating in Quad B mode (Type E). Because it occupies only a single I/O slot, it allows for high-density pulse integration across local, expansion, or remote baseplates.
In order to accommodate diverse sensor types, the IC697HSC700 features 12 sophisticated inputs that users can configure for either single-ended or differential operation. This flexibility extends to voltage requirements as well, as the module successfully manages both 5VDC and 10-30 VDC ranges. Furthermore, the module incorporates four positive logic outputs, which provide 20 mA at 10-30 VDC for direct triggering of field devices. Consequently, these capabilities make the unit a premier choice for demanding applications such as turbine flowmeter regulation, velocity monitoring, and complex material handling sequences.
Safety and uptime remain central to the design of the IC697HSC700. For instance, the module provides a robust isolation barrier rated at 1500V for one second, which effectively shields the backplane from field-side electrical interference. While the module is active, it draws 1 Ampere from the backplane, plus an additional 10 mA for every energized output circuit. To assist technicians during commissioning, the faceplate includes integrated LED status indicators that provide immediate diagnostic feedback for both internal module health and external output circuit integrity. Moreover, because it adheres to rigorous industrial standards, the module maintains reliable performance in high-interference environments.
To ensure seamless operation, the IC697HSC700 requires a Series 90-70 CPU running firmware version 5.0 or higher. Engineering teams can perform configuration and programming through a variety of tools, ranging from the classic Logicmaster 90-70 to modern Windows-based suites like Proficy Machine Edition and VersaPro. In addition to standard serial SNP connectivity, the system supports Ethernet TCP/IP ports for remote management. As a result, this module integrates effortlessly into both legacy installations and modernized control architectures, providing a stable platform for precision motion and position control.
