CC-PUIO31 Honeywell Series C Universal IO Module 32 Channel

CC-PUIO31 Honeywell Series C Universal IO Module – 32 Configurable Channels

The CC-PUIO31 is a Universal Input/Output module from Honeywell Series C. It carries 32 channels. Every channel is user configurable. You can set each one as analog input, analog output, digital input, digital output, or pulse input. The module also supports Sequence of Events with 1 ms resolution. It brings HART 7 support and a HART modem per channel. Electronic short circuit protection guards each output. Open wire detection works on analog and digital channels. The CC-PUIO31 runs from -40 to +70 °C. This module cuts spare part counts by replacing many single-function cards.
