AutomationDirect AD-SSR6T25-DC-480A Solid State Relay

AD-SSR6T25-DC-480A is a panel-mount solid-state relay from AutomationDirect rated to switch 48–480 VAC loads up to 25 A, controlled by a 3–32 VDC signal. This normally open SPST device uses zero-cross switching to minimize EMI and features a green LED indicator for on/off status. The relay comes in the finger-safe hockey-puck style with a thermal mounting pad included, designed for easy installation in control panels. Input terminals are M3.5 and output terminals are M4, with a mounting pad and associated hardware enabling robust heat transfer and secure mounting; typical unit weight is around 100 g. The device provides input-to-output isolation rated at 4000 VAC (rms), and it tolerates standard industrial environments from -40 to +80°C (derating applies). Electrical characteristics specify a minimum load current around 120 mA, a maximum off-state dv/dt of 250 V/µs, and turn-on/turn-off times on the order of half a AC cycle at 50/60 Hz, with a surge capacity up to 250 A for a single cycle. This makes the AD-SSR6T25-DC-480A suitable for automation tasks such as switching lighting, heaters, or other AC loads controlled by a low-voltage DC control signal in PLC or relays-based control schemes.
