Product Description:

The M.1017.3098 analog input block from Danaher belongs to the Block IO Analog Modules series and provides signal acquisition for distributed control racks. It accepts 4–20 mA or ±10 V process signals and converts them to digital data so a PLC can monitor temperature, pressure, or motion without separate conditioners. Integrated isolation between the field and backplane helps protect upstream electronics from common-mode faults while maintaining high channel density in a compact footprint.

The module has 4 channels, and every input is digitized at 14 bits, giving 16,384 discrete steps across the selected range. For current loops, the span error is limited to 0.15% FSR at 25 °C, while voltage ranges remain within 0.2% FSR under the same conditions. A high input impedance of 1 MΩ prevents the module from loading low-power transducers, and a precision 250-ohm sense resistor is fitted for current conversion. Offset is held within ±5 counts at 10 V, and common-mode tolerance is ±20 V with the shield reference open or ±35 V when it is connected to ground. Continuous supply demand on the backplane is 160 mA, supporting the onboard converter and diagnostics.

The module’s filter integrates with control loops through a time constant of 1 ms, balancing noise rejection and response speed. During power-up, the card draws an inrush current of 2.5 A that lasts only 250 µs, limiting disturbance to adjacent loads. Steady-state power dissipation in the sense network is 0.12 W, and overall consumption stays within cabinet cooling budgets. The module measures 4.05 inches wide and 4.825 inches high, allowing side-by-side stacking on a DIN rail. Its common-mode isolation helps protect signal acquisition from voltage differences between connected field devices. The short filter time constant also allows changing process signals to be captured without excessive delay.
