Modular Smart Relay for Automation

The Schneider Electric SR3B261FU is a modular smart relay designed for industrial electrical control and automation tasks. It operates on an input voltage range of 100 to 240V AC and provides 16 inputs alongside 10 relay outputs rated at 8 A each. The unit includes 16 counters, 16 timers, a real-time clock and an integrated LCD display for local monitoring.

Suited for Discrete Logic Control

This relay suits engineers building standalone or distributed control panels that require a fixed complement of 16 digital inputs and 10 relay outputs. It is not intended for applications needing analogue I/O, high-speed motion control, fieldbus communication or safety-rated functions. Buyers who require expandable I/O beyond the fixed counts or integrated networking should look at other platforms.

LCD and Clock Simplify Commissioning

The built-in LCD display and real-time clock allow configuration, diagnostics and time-based scheduling without an external HMI or PC connection. Counters and timers are accessible directly on the front panel, reducing wiring and software overhead for sequence logic. The transparent housing aids visual inspection of status LEDs inside the enclosure.

Questions about this item

What power supply voltage range must I already have available for the SR3B261FU to operate?

The relay runs on any AC supply between 100 and 240 volts, so your existing panel must provide a voltage within that range.

Can I keep my existing 8-amp relay loads when switching to this unit with its 10 relay outputs?

Yes, each of the 10 relay outputs is rated at 8 amps, matching the load capacity of typical 8-amp relay circuits you may already use.

How do I verify the SR3B261FU is running its logic correctly after wiring the 16 inputs and 10 outputs?

The front LCD display shows real-time status of all 16 inputs, 10 outputs, 16 counters, 16 timers and the internal clock, confirming correct operation.
