Features:
- 32 inputs.
- Four isolated groups of eight.
- -3 to +30 VDC range.
32 inputs establishes the principal capability of
IC697MDL650 within its Series 90-70 function.
The relationship between four isolated groups of eight and -3 to +30 VDC range determines how the module fits the surrounding rack, network, or field circuit.
During service, 1 ms or 10 ms input filtering must remain consistent with the saved application and the installed hardware.

Sources that can drive the DC inputs
- Contact devices: Pushbuttons, limit switches, and selector switches are suitable field inputs.
- Electronic sensors: Two-wire and three-wire proximity switches can be used when their on-state drop and off-state leakage remain compatible.
- PLC outputs: An IC697 positive-logic output module can directly drive an input on IC697MDL650.
- IEC characteristic: The positive-logic channels follow the IEC Type 1 input characteristic.
Thirty-two points in isolated groups
- Point count: IC697MDL650 supplies 32 input points to the Series 90-70 controller.
- Group structure: Four isolated banks of eight points provide separate field commons.
- Point indication: Front LEDs display the logic-side state of all 32 channels.
- Addressing: Software configuration assigns I/O references without module jumpers or DIP switches.
Current path and filtering
- Field polarity: The module sinks current from the input device toward the user common or negative bus.
- Nominal level: The field circuit is designed around 24 VDC positive-logic signals.
- Filter choice: A 1 ms or 10 ms input filter is selected to balance response time and noise rejection.
- Leakage tolerance: Up to 2 mA off-state leakage can be accepted without switching an input on.
Checking two-wire and three-wire operation
- On-state drop: Available voltage at the input is checked with the selected sensor conducting.
- Off-state current: Leakage is verified below the level that could create a false on state.
- Group common: The correct common is traced for each isolated bank before energization.
- Commissioning result: Sensor action, channel LED, and the assigned PLC reference are compared point by point.
