6ES7921-3AB00-0AA0端子
微型机控制的仅几点、十几点、几十点，如OMRON公司新推出的ZEN机，主机有8点、10点两种，还有扩展，多可扩到34点。再如西门子的logo机，小的也仅能控制10点。还如三菱的alpha机，I/O点数分别有6、10及20等几种规格，而alphaXL的I/O点数分别有14、24两种规格。这些机型，有的还内嵌有简易的编程工具，很便于编程。由于它的价格低廉、使用方便、工作可靠、体积很小…而且，它的可输出电流比其它PLC都大，有的可达8安培。完全可成为新一代相应的继电器控制的替代品，也因此，有的则称其为可编程继电器（PLR）。


小型机控制点可达100多点，以至于更多。如OMRON公司的CPM2A、CP1H、CQM1H，则分别可达到120、320、512点。西门子公司的S7200机可也达一百多点。新推出S7-200 CN为版机型。当大配置时，控制点数可达248路（西门子称I/O点为路）。三菱公司的FX2N多点数也可达256点，而FX3UC机可达300多点。


中型机控制点数可达近500点，以至于以千点计。如OMRON公司CJ1H机可超过2000多点。德国西门子公司的S7300机多可达512点（开关量），新推出的318-2也可超过1000点（开关量）。此外，还可另加128路模拟量输入或输出。三菱的Q系列的基本型机，控制点数也可达2048点。


大型机控制点数一般在1000点以上。如OMRON公司的。CS1H机大配置可达5000多点。三菱的Q系列的机，控制点数也可达8192点。
