- Sixteen fast-response 24 V DC sourcing inputs
- 0.3 ms maximum on delay and 0.5 ms maximum off delay
- Designed for compatible sinking field devices
1746-ITV16 provides sixteen fast-response 24 V DC sourcing inputs in one SLC 500 slot. It must be paired with compatible sinking field devices.
The module operates over 10–30 V DC. Official data gives maximum input delays of 0.3 ms on and 0.5 ms off, supporting short-duration signal detection.
Because fast inputs can respond to bounce or noise, commissioning should confirm supply polarity, common wiring, cable routing, sensor behavior, and any program filtering used by the machine.
Availability, condition, price, and shipping time for 1746-ITV16 are confirmed during quotation.

- Use compatible sinking field devices with the sourcing input architecture
- Verify the V DC feed, common reference, and sensor polarity
- Do not wire it as a direct replacement for the sinking ITB16 interface
- Fast response can expose sensor leakage, bounce, or coupled noise
- Check cable routing, grounding, and program filtering before replacement
- Validate pulse capture against the actual machine cycle
- Record the installed terminal block and sinking-device arrangement
- Isolate power before transferring conductors to a replacement module
- Confirm sourcing behavior before reconnecting field sensors
- Fast sinking-sensor signal detection
- SLC 500 sequence and position monitoring
