This counter module captures high-speed pulse signals from encoders and proximity sensors. It provides accurate totalization and frequency measurement for production monitoring. The Fuji FTU500A delivers four independent counter channels for versatile application needs. Each channel operates in multiple counting modes for flexible system configuration.

Physical Dimensions and Installation Profile

This counter module measures 120 millimeters in width, 70 millimeters in depth, and 95 millimeters in height. The unit weighs approximately 0.60 kilograms for straightforward DIN-rail mounting. It plugs directly into the NP1 series backplane using a high-reliability connector system. The front panel includes channel status LEDs for real-time operational feedback.

Counting Specifications and Input Capabilities

The Fuji FTU500A accepts input frequencies up to 100 kilohertz on all four channels. Each channel supports incremental encoder signals with A and B phase inputs. The module handles both up/down counting and quadrature decoding modes. It provides a 32-bit counter range from 0 to 4,294,967,295 counts. The input circuitry includes programmable debounce filters for noise immunity.

Input Types and Signal Conditioning

This counter module accepts 5 to 24 VDC differential or single-ended inputs. It provides programmable input thresholds for compatibility with various sensors. The module includes internal pull-up resistors for NPN-type sensor connections. Each channel offers a gating input for enabling or disabling the counter. The input protection circuitry withstands overvoltage up to 30 VDC.

Output Functions and Control Features

The Fuji FTU500A provides four digital outputs for preset value comparison. Each output activates when the counter reaches a user-defined setpoint. The outputs support PWM generation for speed control applications. They also handle frequency measurement output for tachometer functions. The module includes a hardware latch input for synchronous data capture.

Preset Values and Comparison Modes

This counter module stores up to four preset values per channel for comparison logic. It supports equal-to, greater-than, and less-than comparison conditions. The module outputs control signals based on the comparison results. Users can reconfigure the preset values during operation without module interruption.
