Analog input module with HART protocol for CompactLogix PLCs. Maximize I/O performance by combining real-time analog and HART data acquisition at a fraction of the cost. It provides CompactLogix PLCs with full analog capability and the benefit of HART (highway addressable remote transducer) protocol in an I/O module. This module offers four channels of analog input each easily configured for voltage or current signals. The module also act as a HART master, allowing communication with HART field devices. HART data is available directly on the network. It features full read or write HART capability. Pass-through messaging capability. HART PV, SV, TV, FV along with analog data. Isolation 500 VDC channel-to-channel, 500 VDC channel-to-backplane isolation.
