Integrator's quick take
Side-by-side mounting is allowed, which saves rail space in a dense panel. The IP20 front means finger-safe when installed in an enclosure, but the terminal area is IP00 — keep that in mind for live-work clearance.
If your application is pure resistive heating or lighting, the AC-1 maximum switching rate of 1 000 cycles per hour tells you how fast you can cycle it thermally. The coil draws are listed across the voltage range: 10 A at 24 V, dropping to 0.3 A at 220 V.
Compliance documentation is straightforward: the substance prohibitance date of 05/01/2012 confirms RoHS compliance.
Dimensions are 55 mm wide, 112 mm high, 115 mm deep — that's the S2 footprint. It fits alongside other SIRIUS S2 components on the same DIN rail without extra spacing. The screw terminals accept solid wire from 0.25 to 2.5 mm² for the control circuit, and stranded from 0.75 to 25 mm² for the main circuit, so common panel wire sizes are covered without adapters.
