Phoenix Contact 2967578 SSR Relay SPST-NO 100mA 3-48V Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2967578 is a solid-state relay (SSR) module configured as SPST-NO (Single Pole Single Throw - Normally Open) with a 1 Form A circuit. This component is designed for DIN rail mounting and operates with a 24VDC input signal to control DC loads between 3V and 48V at 100mA maximum current. The 2967578 belongs to the PLC-OSP series and is classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2967578 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) — the relay must provide identical switching topology
• Output Type: DC — load switching must be direct current only
• Voltage - Input: 24VDC — control signal voltage must match exactly
• Voltage - Load: 3V ~ 48V — output voltage range must encompass or match the original specification
• Load Current: 100mA — maximum switching current must be at or above this threshold
• Mounting Type: DIN Rail — physical form factor and installation method must be identical
• Termination Style: Spring Terminal — connection method must be compatible
• Package / Case: Module — enclosure type must be equivalent

The Phoenix Contact 2900358 satisfies all substitution criteria. Both components share identical electrical specifications, circuit topology, and mechanical form factor. The primary distinction is product status: the 2900358 is active and available, whereas the 2967578 is obsolete. Both comply with RoHS standards and feature unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 2900358 be used as a direct replacement for the 2967578 in existing installations?

A: Yes. The 2900358 is electrically and mechanically identical to the 2967578. Both components feature the same 24VDC input, 3V–48V DC output range, 100mA load current rating, DIN rail mounting, and spring terminal connections. Direct substitution is supported without circuit modification.

Q: What is the difference between the PLC-OSP and PLC-OPT series?

A: The PLC-OSP series (2967578) is obsolete. The PLC-OPT series (2900358) is the active product line from Phoenix Contact. Both series share identical electrical specifications and form factors. The series designation change reflects Phoenix Contact's product portfolio evolution.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS compliant. The 2967578 carries RoHS Compliant certification, while the 2900358 carries ROHS3 Compliant certification. Both meet current environmental and regulatory requirements. The 2900358 reflects the latest compliance standard.

Q: Does packaging affect substitution compatibility?

A: The 2967578 is supplied in standard packaging, while the 2900358 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance. Selection between packaging options depends on procurement and inventory requirements.

Q: What load voltage and current ranges are supported?

A: Both the 2967578 and 2900358 support DC load voltages from 3V to 48V and maximum load current of 100mA. These specifications are identical and determine the maximum power switching capability of the relay module.
