The EX1200-1538 is a high-performance multifunction card that provides 8-channels of independent 32-bit counters, 16 channels of isolated digital I/O, and 2 channels of isolated analog output (DAC) on a single card. The wide range of measurement functions make this card suitable for both electronic functional test, as well as precision data acquisition applications. Combining the EX1200-1538 with the DMM and switch capabilities allows for a complete measurement, control, and distribution system in a small 1U rack space.

Counter channels accept both analog and digital inputs ranging from ±48 V of true differential voltages which makes it suitable to use with almost any real world signal without the need for external signal conditioning. Programmable hysteresis and threshold levels over the entire input voltage range can help to extract the fundamental frequency from the noisiest analog input signals. Electronic counter channels can directly measure the RPM from tooth wheel and other types of sensors.

The EX1200-1538 isolated digital I/O channels can be configured as input or output on a per channel basis. Each channel is isolated from each other and can accept voltages from 2.5 V to 60 V. The output channels use solid-state switches that work in any polarity.

The isolated analog output channels are independently configurable as either constant voltage or current mode. The output range is fixed (±10 V in voltage mode and ±20 mA in current mode) and the output levels are programmable with 16-bit resolution. Both channels are isolated from each other and fully protected, providing the capability to be connected in series or parallel for an even wider output range.
