Product details

DIN-rail I/O slice with 16 in / 16 out

The Omron SRT2-MD32ML-1 is a 24 VDC I/O module that packs 16 digital inputs and 16 solid-state outputs into a single DIN-rail slice, designed for use with the Omron C Series PLC family.

Obsolete — sourcing through independent channels

Omron has classified the SRT2-MD32ML-1 as obsolete. No official replacement order code is on record. For BOM lines that still reference this module, availability is limited to surplus and independent-distribution stock.

Fit for C Series backplanes

The module mounts to a DIN rail and connects to the PLC backplane via a rectangular connector — no screw terminals on the module face. The 16 digital inputs sink 24 VDC field signals; the 16 solid-state outputs switch DC loads without mechanical relay wear. Rated for operation from -10°C to 55°C, with CE marking for European regulatory acceptance.

Frequently asked questions

Is the Omron SRT2-MD32ML-1 obsolete?

Yes, Omron lists the SRT2-MD32ML-1 as obsolete. No direct factory replacement order code has been published.

What is the replacement for SRT2-MD32ML-1?

Omron has not issued an official replacement order code for the SRT2-MD32ML-1. For a functional equivalent within the same form factor, the CP1W-32ET output module offers 32 solid-state outputs on a DIN-rail mount but uses screw terminals and is designed for the CJ/CP1 series, not the C Series backplane of the SRT2.

Does SRT2-MD32ML-1 work with Omron C Series?

Yes, the SRT2-MD32ML-1 is specified for use with Omron C Series PLCs. It connects via a rectangular connector to the C Series backplane.
