The HE670ADC840 provides eight analog channels with a resolution of 12-bits. Isolation levels are 400VDC (channel-to-channel) and 1,000VDC (channel-to-ground). The module changes the current input signals into digital values, which can be accessed through communications with the Bus Interface Unit. These modules are protected within the standard Field Control I/O case and are compatible with a variety of I/O bases providing flexible termination options.
