Product details

The Omron SRT2-ID04-1 is a 4-point digital input module from the SRT2 series, designed for the C Series automation platform. It accepts 24VDC field signals and reports them via the backplane to the CPU. Screw terminals and DIN rail mounting keep field wiring straightforward — strip, terminate, clip onto the rail. The 24VDC supply is shared with the backplane; verify the current draw against the CPU's power budget.

Integration Note

Mounts on standard DIN rail via screw terminals. The C Series backplane provides addressing; no DIP configuration needed for basic 4-input operation.

Frequently asked questions

What type of module is the SRT2-ID04-1?

It is a Type Input Module: 4 digital inputs, 24VDC, designed for use with Omron's C Series platform.

What compliance approvals does the SRT2-ID04-1 carry?

It holds CE, CSA, and UL approvals for industrial control equipment.

Will the SRT2-ID04-1 replace a CP1W-32ET in a panel?

No. The CP1W-32ET is a 32-point solid-state output module for the CJ/CP1 Series, while the SRT2-ID04-1 is a 4-point digital input module for the C Series. They serve different platforms and I/O roles.
