AFP7AD4H Panasonic FP7 Analog Input Unit – 4 Channels, 16-Bit, High-Speed and High-Accuracy
The Panasonic AFP7AD4H is the high-speed, high-accuracy analog input unit for the FP7 PLC. It provides 4 voltage/current input channels, each selectable on its own, with resolution up to 16 bits (1/62,500 on the ±10 V range). Conversion runs as fast as 25 µs per channel, and overall accuracy is ±0.05 % F.S. at 25 °C. The channels are isolated from each other by PhotoMOS relays and from the internal circuits by photocouplers and an isolated DC/DC converter. This keeps signals clean in noisy machine environments and allows sensors at different potentials to be connected safely. Built-in digital processing (averaging, scaling, offset and gain), min/max hold, limit comparison, broken-wire detection and a triggered buffer function reduce PLC programming. These features make the unit suited to high-speed measurement, quality inspection and precise process control.
