Product details

The control voltage accepts both 24 V AC and 24 V DC, making it straightforward to integrate into a 24 VDC control circuit common in panel builds. Its 16 A rating at cos φ 0.6 means it handles moderate inductive loads — think contactor coils, small solenoid valves, or signal lamps — without derating concerns at that power factor.

Occupies a single width unit (18 mm), so it fits tight panel layouts. Overall dimensions: 90 mm height, 55 mm depth. The 230 V AC supply side and 24 V control side are isolated within the same housing — wire the control loop from a PLC digital output or a separate 24 VDC power supply.
