The IC693MDL740G is a sourcing DC output module for GE Fanuc / Emerson Series 90‑30 PLCs, designed to convert the PLC’s internal 5‑V logic outputs into switched 12/24 VDC power for external field devices. The module has 16 output points organized in 2 groups of 8 outputs each, with a shared positive power common per group; this configuration is ideal for driving contactor coils, intermediate relays, DC solenoid valves, motor starters, indicator lamps, buzzers, and horns directly from the PLC output rack, reducing the need for additional external relays. The positive‑logic, source‑type output means the module supplies positive current from the user‑provided 12/24‑VDC power rail through the connected load to ground, which is compatible with common DC‑load wiring schemes in industrial control panels.
Technically, the IC693MDL740G is rated for 12–24 VDC output voltage (with a typical 20% / –15% tolerance, i.e., roughly 10.2–28.8 VDC), and each output channel can switch up to 0.5 A DC, while the maximum total current per 8‑point group is 2 A. This limits how many high‑current loads can be connected per group, which is why external fusing per load or per group is recommended to protect the module from short circuits or overloads. The module can handle inrush current up to 4.78 A for 10 ms, which is important for starting inductive loads such as relay and solenoid coils with high initial current draw. The on and off response times are very fast, typically 2 ms maximum, ensuring near‑real‑time control that matches the PLC scan‑cycle performance. The module draws only about 110 mA from the 5‑V backplane bus when all outputs are on, making it electrically efficient in the 90‑30 rack.
Mechanically, the IC693MDL740G is a card‑type PLC‑I/O module that plugs into the Series 90‑30 backplane of 5‑ or 10‑slot substrates, with a front‑panel row of status LEDs (one per output point) to indicate the on‑/off state of each channel for quick troubleshooting and commissioning. The module is rated for wide operating temperatures (typically −40 °C to +70 °C storage, with 0 °C to +60 °C recommended for continuous operation) and 5–95% non‑condensing humidity, suitable for most industrial PLC‑cabinet environments. The field‑side outputs are isolated from the 5‑V logic side by 1500 VDC and between groups by 500 VDC, enhancing noise immunity and safety in high‑voltage plants. Because the module itself has no internal fuses, application guidelines stress external overcurrent protection and adequate heat‑dissipation spacing when placing multiple high‑density DC‑output modules in a rack.
