CTI is pleased to announce the release of the 2557-A 16-Channel Isolated RTD Input Module for 2500 Series® Classic I/O. The 2557-A replaces the older 2557 and uses a removeable field wiring connector. This new connector makes module swaps easy, since it can be simply unplugged from the old module and plugged onto the new one. We will continue to provide support and repairs for the 2557, subject to availability of parts.
