What Is the 170ADM34000?
The 170ADM34000 is a discrete mixed I/O base module from Schneider Electric’s Modicon Momentum series. It packs 8 DC inputs and 8 relay outputs into a single compact unit, which makes it a practical choice when a control panel needs both signal reading and switching in one slot. The module runs on a 24V DC supply and draws a maximum of 5 W.
Because this part is discontinued, buyers should treat it as a replacement or spare-stock purchase. SpareTechPLC lists it for teams that need to keep existing Momentum installations running without a full platform migration.
Key Specifications at a Glance
Three parameters matter most when you evaluate this module.
Channel count and mix. The 170ADM34000 provides 8 inputs plus 8 relay outputs. That 8+8 layout suits panels where digital sensing and load switching sit close together, reducing the number of separate cards you need.
Relay output type. Outputs are normally open relays with AC/DC universal output voltage. This flexibility lets the same module switch different load types, which simplifies spare-part planning across mixed panels.
Physical footprint. At 125 × 141.5 × 47.5 mm and 0.4 kg, the unit mounts in tight enclosures. The IP20 rating means it belongs inside a protected cabinet, away from dust and moisture.
Where It Fits in Real Installations
Packaging and material handling
Conveyor lines often need input signals from photo-eyes and limit switches plus relay outputs for diverters and motor starters. The 24V DC input side matches common sensor wiring, while the relay side handles the switching loads.
Legacy Momentum panel support
Plants still running Modicon Momentum racks face a shrinking supply of discontinued modules. Keeping a spare 170ADM34000 on the shelf shortens unplanned downtime when an existing unit fails.
Building and process control cabinets
The AC/DC universal relay outputs allow use across different control voltages inside one cabinet. That reduces the variety of spare modules a maintenance team must stock.
Installation and Setup Notes
Mount the module inside an enclosure that maintains the IP20 protection level. Keep the 24V DC supply within the stated range and confirm the relay output circuit matches your load type before commissioning.
Because the data does not include isolation, diagnostics, or response-time figures, do not assume those features. Plan your wiring and testing around the documented capabilities only. Always follow Schneider Electric’s installation documentation for the Modicon Momentum platform.
Maintenance and Reliability
Relay outputs are electromechanical, so they are the natural wear point. Inspect relay contacts periodically and replace the module if switching becomes unreliable. Keep the cabinet clean and within a stable environment to protect the electronics.
For a discontinued part, reliability planning means holding spares. A single shelf unit can prevent hours of line downtime, which usually costs far more than the module itself.
Compatibility and Integration
This module belongs to the Modicon Momentum family, so it integrates with Momentum base and processor assemblies. Confirm your existing rack, terminal base, and wiring scheme match the 170ADM34000 before ordering. The data does not list specific communication protocols, so verify network requirements against your current system documentation.
Buyer’s Checklist Before You Order
- Confirm you need 8 inputs and 8 relay outputs, not a different channel mix.
- Verify your input signals are 24V DC and your output loads suit normally open relays.
- Check that the 125 × 141.5 × 47.5 mm footprint fits your enclosure.
- Confirm your supply provides 24V DC and can handle 5 W maximum consumption.
- Ask SpareTechPLC about current stock, condition, and replacement options for this discontinued module.
Frequently Asked Questions
Is the 170ADM34000 still in production?
No. The data marks it as discontinued, last verified in 2026-09. Contact SpareTechPLC to confirm availability.
What outputs does it use?
It provides 8 relay outputs, normally open, with AC/DC universal output voltage.
What input voltage does it accept?
The inputs operate at 24V DC, matching the 24V DC supply voltage.
Does it offer channel isolation or diagnostics?
The available data does not list isolation or diagnostics, so plan accordingly.
What protection rating does it carry?
IP20, which means it must sit inside a protected enclosure.
