X20DC11A6
The X20DC11A6, produced by B & R Automation, is a versatile digital counter module designed for processing digital signals. It features an ABR incremental encoder requiring a symmetrical 5V supply and supports a maximum frequency of 5 MHz with a counter size of 16 or 32 bits. The module demands a minimum differential slew rate of 1 V/µs and supports a maximum current of 300 mA. Additionally, it provides two digital input channels with a nominal 24 VDC, tolerating a voltage deviation of -15% to +20%. These channels function as sinks, sustaining a maximum input current of 3.3 mA with an input resistance of 7.03 kOhms. The channels are non-isolated but isolated from the main bus and accommodate both horizontal (-25 to 60°C) and vertical (-25 to 50°C) installations. It requires non-condensing relative humidity between 5-95% during transport, operation, and storage.
