24 TTL Digital I/O & Counter RS-232 Controlled Module Description The IA-3324 is an RS-232 based digital I/O & counter controller. The digital I/O is divided into three bytes of 8 bit each, while each byte may be used as an input or output port (software setting). Reading the input channel may be done either by polling or by COM interrupt triggered on any data change. The counter supports both event counting and quadrature encoder input. The module is controlled through a standard PC RS-232 COM port and responds to a simple ASCII command-set. Applications Gate control Central control systems Factory floor control Intelligent alarm systems Laboratory instrumentation control Data acquisition and control applications. Features 24ch Digital I/O Readback of output channels status Standard connector and pinout Up to 256 modules (4096 channels) on a single RS-232 port Specifications Control COM Communication Method: Wiring Method: TTL / DRY CONTACT INPUT Voltage Range: Logic ‘0’ Range: Logic ‘1’ Range: TTL OUTPUT FAN Out Output Drive COUNTER Mode Max Frequency Event Counting / Quadrature Encoder Input 100Khz GENERAL Supply Voltage: Current Consumption: Environment: Dimensions: Weight: Ordering Information: IA-3324 - 24 Digital I/O & Counter RS-232/422/485 Module IA-3324L - 24 Digital I/O & Counter RS-232 Module TBL-6822 - Screw terminal board & Status indicator PS-1205 - 12V Power Supply Specifications subject to change without notice.
