Features:
- Sixteen DC inputs: consolidates discrete sensors in one SLC slot
- Sinking interface: requires the documented complementary field-device polarity
- Single common: all 16 channels share one field reference group
1746-IB16 provides a dense 16-point DC input interface for a modular SLC 500 chassis.
Its sinking topology and one-common construction place field polarity ahead of software diagnosis.
The documented off-state and delay limits help separate real field changes from leakage or transient behavior.
Apter Power can review 1746-IB16 Series, terminal block, input polarity, official documentation, condition, and sourcing scope.

- Sensor polarity: pair the module with a compatible sourcing field output
- Common reference: verify the shared return before landing any channel
- Point map: label each conductor against the controller input address
- Off-state limit: measure residual current when a field device should be open
- False-on split: compare terminal voltage, channel LED, and input image
- Corrective path: resolve sensor, wiring, or reference leakage before editing logic
- Block identity: retain the approved removable terminal block and keying
- Torque record: inspect conductor preparation and tighten to official requirements
- Staged test: stimulate each sensor once and confirm the intended program address
- Proximity and limit sensing: collect compatible 24 V DC machine-state signals
- Panel pushbuttons: monitor discrete operator commands with a shared DC reference
- Auxiliary status: bring relay or solid-state indications into an SLC 500 controller
