Description
The CN6221 Series is an FMapproved limit controller that can beconfigured either as a high limit oras a low limit controller. The CN6221features universal input, Optional 2 alarmoutputs, Optional retransmission output, atimer to count the total time thesetpoint is exceeded, and a registerto retain the maximum. The RS485communication interface is availableas an option.
