Schneider Electric RSL1PVBU Slim Interface Relay 24 V

RSL1PVBU slim interface relay with socket: overview

RSL1PVBU is a Harmony RSL slim interface relay delivered pre-assembled on its own socket. The unit is only 6.2 mm wide, carries one changeover contact rated 6 A, and runs from a 24 V AC/DC control signal with an LED and a protection module already fitted.

Pre-assembly saves wiring time on panels with many digital outputs: the relay, coil protection and socket come as one component, with screw connectors for the conductors. The datasheet we hold is dated 8 Nov 2026, and Seven Star LLC supplies RSL1PVBU in Oman and the GCC as an independent supplier in Muscat.

Control circuit and contact limits of RSL1PVBU

The control input is 24 V AC/DC with limits of 21.6–28.8 V, so it accepts either a PLC output rail or a small AC control supply. The datasheet gives an average coil resistance of 3390 Ω (DC), average consumption of 0.17 W DC and a drop-out threshold of ≥ 0.05 Uc, meaning the coil must fall to a low voltage before the relay releases.

That low drop-out matters on PLC outputs that leak: check that the off-state leakage of the output plus any parallel LED or surge element cannot hold the coil above 5 % of 24 V. Contact data for RSL1PVBU: 6 A at 250 V AC in AC-1, maximum 1500 VA, minimum 100 mA at 12 V, which means it is a power-level contact and not intended for dry-circuit signals.

Operate time is 12 ms and reset 5 ms. Contact life is 60000 cycles at 6 A, 250 V AC-1, against 10000000 mechanical cycles; operating rate under load is limited to 360 cycles per hour.

Installation and maintenance

Snap the assembly onto a 35 mm rail, wire the coil and contact terminals within the 0.5 N·m limit, and test with a known load before closing the panel. Since the relay is pre-assembled, replacement means replacing the module; label each channel so that a swap is quick.

The datasheet gives IP40 and an ambient range of −40 to 55 °C, so keep it in an enclosure with adequate ventilation, and do not stack heat-generating devices directly beside a row of these relays.

Selection and ordering checklist for RSL1PVBU

Before ordering RSL1PVBU, confirm:

• The control signal is 24 V AC or DC within 21.6–28.8 V, and the output driver leaks little when off.
• One changeover contact of 6 A is sufficient; otherwise a multi-contact relay is needed.
• The load is not below 100 mA at 12 V, which is the stated minimum.
• Screw connector sizes up to 2.5 mm² suit your wiring.
• Rail space and clearance for a 6.2 mm wide, 78.6 mm tall module.

Related relay and socket parts

Within the Harmony Electromechanical Relays range, the RSB series interface relays (for example RSB2A080BD, 8 A, 2 C/O) are wider but offer two contacts and plug into separate sockets such as RSZE1S48M. RSL1PVBU is the choice when width and a pre-assembled build matter more than contact count or relay replacement without rewiring.

RSL1PVBU technical specifications

Where RSL1PVBU is used in Oman and the GCC

Slim interface relays like this fill terminal strips between PLC and field in water treatment, power distribution, oil and gas skids and building management panels. This unit is a fit where a single changeover contact per channel is enough and cabinet space is the constraint.

Heat is the main environmental factor in Gulf installations; the 55 °C operating ceiling in the datasheet is a real design limit for sun-loaded cabinets, so verify enclosure temperature rise in summer.

Why the 6.2 mm width matters

Interface relays are mounted in rows. At 6.2 mm per channel, a 16-channel marshalling strip needs about 100 mm of rail for the relays themselves, which is a large saving over a 15.5 mm wide socket such as the RSZE1S48M. For this unit, the 78.6 mm height and 95 mm depth should still be checked against duct clearance and door depth.

The compression-spring fixing described in the datasheet and the screw connectors keep terminations accessible from the front, which helps when a loop has to be traced under time pressure.
