When used in combination with an I\/O module, the response time can be up to 22 ms. The actual system response therefore depends on the combined adaptor and I\/O module configuration.\u003c\/p\u003e\n\u003cp\u003eThe A2SDV105 uses the 5 V DC internal power supply, with a maximum current consumption of 14 mA.
