IC695ALG616: 16 Single-Ended or 8 Differential Inputs at 24-Bit
The IC695ALG616 is the high-channel-count analog input module for PACSystem RX3i, and its defining property is that the same 16 physical terminals serve as either 16 single-ended or 8 differential inputs. That configurability is what lets one module cover both a single-ended instrumentation load and a differential load without changing hardware.
It is a non-isolated module, which is the trade-off behind the channel density. Where ground potentials differ across the loops, a non-isolated module is the wrong choice — this one is for a rack where the loops share a common reference.

RX3i Analog Input Modules
RX3i analog input modules differ in isolation, channel count, resolution and signal types accepted. All four determine whether a module fits both the rack and the loops:

Single-Ended Versus Differential: What Changes in the Field
Single-ended reads one signal wire against module common; differential reads the signal across a pair. Differential rejects common-mode noise and is the right choice on long runs or in a noisy environment; single-ended halves the wiring and is adequate where the loop is short and quiet.
The failure mode when the mode is wrong is subtle: a differential loop configured as single-ended will read approximately half the expected value rather than failing, so it can pass a quick functional check while being wrong. Confirm the configuration against how the loops are actually wired.
Resolution and When It Matters
24-bit resolution is meaningful where the measurement is a small fraction of the full-scale range. Where the process value sits at mid-scale, a lower-resolution module would be adequate and a higher-resolution one buys nothing. Confirm where in the range the loops actually operate before treating resolution as a deciding factor.
