The Allen-Bradley 1756-IF6I is a six-channel isolated analog input module for ControlLogix controllers. Each channel accepts voltage or current signals with galvanic isolation from the backplane and between channels, rated for 250 V continuous isolation (with routine testing up to 1350 V AC for 2 seconds). The module uses a 20-pin terminal block interface and is compatible with standard removable terminal blocks 1756-TBNH, 1756-TBSH, 1756-TBCH, and 1756-TBS6H. It is designed for use in ControlLogix backplanes to measure isolated analog inputs while protecting the controller from noise and transients.
