170ARM37030
Schneider Electric
Overview
The 170ARM37030 is a Discrete relay I/O base AC in the Modicon Momentum automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon 170 ecosystem.
Application & Technical Notes
As a discrete relay i/o base ac, the 170ARM37030 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon 170 equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Schneider Electric platform.
Key published characteristics include a Limits 3–30 V rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the 170ARM37030, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your Modicon 170 installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
