| Manufacturer Technical Reference | Phoenix Contact REL-MR- 24DC/21, Item 2961105, Official Product Datasheet |
The Phoenix Contact NO.2961105, officially designated REL-MR- 24DC/21, is a miniature electromechanical relay featuring a 24 VDC coil. Its monostable switching design supports compatible industrial signal and control circuits.
A single SPDT changeover contact provides normally open and normally closed switching paths. The contact supports a limiting continuous current of 6 A, subject to the load-specific switching ratings and appropriate circuit protection.
The relay measures just 5 × 28 × 15 mm, making it suitable for compact relay assemblies and high-density control panel installations using an appropriate relay base.
Typical operate and release times of 5 ms and 2.5 ms respectively provide mechanical switching response suitable for many industrial automation applications. Timing depends on the electrical and operating conditions.
The relay is specified with a 4 kVAC coil-to-contact dielectric test voltage for one minute, supporting electrical separation between compatible control and switched circuits.
The REL-MR construction supports plug-in or solder connections and is used in compatible Phoenix Contact RIF-0 relay assemblies. Select the correct socket or base separately when replacing or installing the relay.
We support online purchase of the Phoenix Contact NO.2961105 Plug-In Miniature Power Relay. If you need to make bulk purchases and inquire about other products, please contact our team to inform us of your purchase requirements. We will provide you with information such as quantity quotations, delivery dates, and transportation methods.
What is Phoenix Contact NO.2961105?
It is a Phoenix Contact miniature plug-in electromechanical power relay with a 24 VDC coil and one SPDT changeover contact. The official manufacturer designation is REL-MR- 24DC/21.
What is the official Phoenix Contact part number?
The manufacturer item number is 2961105. NO.2961105 refers to the same item number, and REL-MR- 24DC/21 is its official product designation.
What coil voltage does the relay require?
Its nominal coil voltage is 24 VDC. Phoenix Contact lists an input voltage range of 14.4 to 66 VDC with additional conditions shown in the manufacturer's voltage operating diagram.
Does the relay have normally open and normally closed contacts?
Yes. The relay has one changeover contact, also called SPDT or 1 Form C, providing one common terminal, one normally open path and one normally closed path.
What is the contact current rating?
The limiting continuous contact current is 6 A. The permissible switching current depends on the load type and voltage, so the relevant AC-15, DC-13 or resistive load ratings must also be checked.
Can it switch a 250 VAC load?
Yes, within its specified electrical ratings. The maximum resistive switching capacity is 1500 VA at 250 VAC, while inductive loads have different permissible current limits.
Can the relay switch 250 VDC at 6 A?
No such capability should be assumed. Although the maximum switching voltage is listed as 250 VAC/DC, DC interruption ratings are substantially lower at higher voltages. Consult the manufacturer's load-specific ratings before switching DC circuits.
What are the relay switching times?
The typical operate time is 5 ms and the typical release time is 2.5 ms under manufacturer-specified conditions.
How long is the relay's mechanical service life?
Phoenix Contact specifies a mechanical service life of 20 million cycles. Actual electrical contact life varies with the load and operating conditions.
Does the relay include a DIN rail socket?
The item 2961105 identifies the individual plug-in relay. A compatible socket or relay base is required for a typical DIN rail installation and should not be assumed included.
Is 2961105 compatible with Phoenix Contact RIF relay assemblies?
Yes. Phoenix Contact identifies the relay in assemblies including RIF-0-RPT-24DC/21, RIF-0-RPT-24DC/1 and RIF-0-RPT-M-24DC/21. Confirm the exact socket and wiring arrangement before installation.
What is the difference between Phoenix Contact 2961105 and 2961192?
The primary difference is the contact material: Phoenix Contact 2961105 (REL-MR- 24DC/21) uses standard silver tin oxide (AgSnO) contacts suitable for standard power switching up to 6 A, whereas 2961192 (REL-MR- 24DC/21AU) features hard gold-plated contacts designed for reliably switching low voltages and dry signal circuits without oxidation.
