The IMDSI22 Digital Input Module consists of a single printed circuit board that occupies one slot in a module mounting unit. It monitors two separate groups of eight digital inputs. Twelve inputs are isolated from each other; the remaining two pairs share common positive input lines. Two captive screws on the module faceplate secure it to the module mounting unit. Sixteen front panel LED status indicators (group A and group B) display the input status and provide aid in system test and diagnosis. The digital input module has three card edge connectors for external signals and power (P1, P2 and P3). P1 connects to common (ground) and +5 VDC power. P2 connects the module to the I/O expander bus to communicate with a controller. P3 inputs the digital signals using a cable connected to a termination unit. The terminal blocks (physical connection points) for field wiring are on the termination unit.

The IMDSI13 supports only 24 VDC inputs and the IMDSI14 supports only 48 VDC inputs, both being fixed-configuration modules, whereas the IMDSI22 is a universal module configurable via jumpers to accept 120 VAC, 24 VDC, 48 VDC, or 125 VDC inputs.
No. While the module provides 1500 VDC isolation between inputs and logic circuitry, only twelve inputs are isolated from each other; the remaining two pairs, specifically points A7/A8 and B7/B8, share common positive input lines and must therefore use the same contact voltage.
TConfiguration is performed through thirty-two jumpers on the module: odd-numbered jumpers (J1, J3, J5 through J31) select the working voltage, while even-numbered jumpers (J2, J4, J6 through J32) select AC or DC mode by strapping pins 1-2 for AC or pins 3-4 for DC.
