　　8LVA33.R0021D000-0 High-density four- and eight-channel modules offer twice as many channels per module in the same standard expansion module enclosure size.EM231 Series eight-channel analogue input modules support industry-standard unipolar 0-10VDC, 0-5VDC, 0-20mA and bipolar ±5VDC, ±2.5VDC input signals. The EM232 series four-channel analogue output modules support both 0-10VDC and 0-20mA output signals.EM231 TC Eight-channel thermocouple temperature input modules support seven different thermocouple sensor types and ±80mv input signals, enabling them to perform in a variety of temperature control applications.EM231 RTD The new four-channel RTD temperature input modules support eight different RTD sensor types and 150 ohm, 300 ohm and 600 ohm resistance inputs.

　　Easy-to-use, fully integrated power converters are available, including MOSFETs, inductors, and internal input and output capacitors in 10x10x4mm and 12x12x4mm packages, respectively. The XR79115 use Exar's emulated current-mode COT control scheme, which provides the fast transient response of a traditional COT control loop while delivering excellent line and load regulation performance. Exar's COT control loop can be operated with ceramic output capacitors, eliminating the need for a loop compensation component, which is the key to high module integration.
