Description: The IC200MDD840 is a 32-point combination discrete I/O module in the VersaMax I/O family, formerly manufactured by GE Intelligent Platforms and now part of Emerson Automation. The module has twenty (20) 24 VDC positive logic inputs and twelve (12) Type A 2.0 Amp rated relay contact outputs. The module has a maximum backplane current draw of 375 mA.

About the IC200MDD840

The IC200MDD840 is a component module in Emerson Automation’s VersaMax product family, formerly known as the General Electric Intelligent Platform (GE IP). The module is a combinational I/O module with embedded discrete input and output circuitry such as ten (10) positive logic 24 VDC inputs and twelve (12) A- or normally open (N.O.) contact outputs. The module has a maximum backplane current of 375 mA.

The input channels are divided into two (2) groups of ten (10) input channels each. Input characteristics include: input voltage compatibility from 0-30 VDC (24 VDC nominal); on-state voltages from +15 to +30 VDC; off-state voltages from 0 to 0.5 mA; typical on-state and off-state signal transition delays of up to 0.5 ms; and input impedance of up to 10k ohms. The input channels have configurable filtering times for both electrically and mechanically noisy input channels, eliminating false-positive and false-negative signals. These filter times include 0 ms, 1.0 ms, and 0.7 ms, with the default configuration being 1.0 ms.

The relay output channels are divided into two (2) groups dcs-sis.com of six (6) channels each. The contact outputs are rated at a minimum of 10mA per point; maximum current per module is 8.0A; 2.0 amps at 5 to 265VAC, maximum with resistive load; 2.0 amps at 5 to 30 VDC, maximum with resistive load; and 0.2 amps at 31 to 125 VDC, maximum with resistive load. Module relay types are fixed coil, moving armature, and silver alloy contact types.
