Features:
- Sixteen 120 VAC input points in one common group
- Individual point LEDs provide direct field-state indication
- 1,500 V isolation separates the AC input section from PLC logic
IC693MDL240 converts a bank of line-voltage contact states into discrete data for the Series 90-30 CPU.
Its single-common topology favors groups of devices powered from the same AC branch.
External field power supplies the sensing circuit; the backplane handles the logic interface and status transfer.
The General Electric IC693MDL240 Series 90-30 120 VAC 16-point input module may remain available for quotation and installed-system support from Apter Power.

AC input behavior
- Input range: Each channel accepts a 0 to 132 VAC signal at 50 or 60 Hz.
- Point grouping: All sixteen inputs return through one shared common terminal.
- State display: A dedicated LED follows the logic state of every input point.
- AC-only design: The sensing network is designed for alternating-current devices, not DC substitution.
Source and device connections
- External source: Field voltage is provided outside the module and routed through the connected device.
- Contact devices: Pushbuttons and mechanical limit switches can complete the AC input path.
- Electronic sensors: Compatible proximity switches may be used when their off-state leakage stays within the input requirements.
- Common integrity: All points must share the intended branch reference without mixing unrelated AC sources.
Control-side protection
- Logic separation: The field section withstands 1,500 V relative to the backplane logic.
- Group limitation: Isolation applies to the input group as a whole, not between individual channels.
- Troubleshooting: An illuminated point LED helps distinguish field activity from program-side logic.
- Panel practice: Line-voltage conductors remain segregated from low-level and communication wiring.
Supported input uses
- Operator stations: Illuminated pushbutton and selector-switch contacts can report machine commands.
- Travel detection: AC limit switches provide end-of-stroke and position status.
- Conveyor sensing: Compatible proximity devices can detect products or carriers on material-handling equipment.
- Utility monitoring: Auxiliary contacts from starters, relays, and protective devices can supply sixteen shared-common status points.
