Detailed Description

Solid State Relay for AC loads. SPST-NO (1 Form A). 50 A continuous load current (with proper heat sink). Load voltage 24–280 VAC. DC control input 3–32 VDC. Zero-cross turn-on for lower EMI and smoother switching. Chassis-mount “hockey puck” module with screw terminals. RoHS compliant. From Crydom’s 1 Series. Bulk packaging. Output type AC, Zero Cross.

Key Features

AC output SSR with zero-cross switching for cleaner turn-on and reduced electrical noise

SPST-NO (1 Form A) circuit for simple on/off control of one AC load

50 A load current rating with correct heat sinking and airflow

Wide load voltage window: 24–280 VAC

Wide control input: 3–32 VDC, compatible with many PLCs and controllers

Chassis/panel mount “hockey puck” form factor

Screw terminals for secure wiring and easy field service

Optical isolation between input and output for safety

RoHS compliant; common safety/agency approvals on series (see datasheet)

Bulk pack option for production lines

Key Advantages

No mechanical contacts: silent operation, long life, and high reliability

Handles high currents up to 50 A for heavy heaters, motors, and industrial loads

Zero-cross reduces inrush on resistive loads and limits EMI

Fast switching and consistent performance vs. electromechanical relays

Simple wiring with four screw terminals; easy to mount to a chassis or heat sink

Wide control input range simplifies interfacing with 5 V, 12 V, and 24 V logic

Robust epoxy-encapsulated construction resists vibration and dust

Strong stock position: 2687 units available for quick shipment from Y-IC

Packaging

Type: Panel/chassis-mount “hockey puck” SSR module

Material: Epoxy-encapsulated body with thermally conductive base; flame-retardant housing; metal base plate for heat transfer

Size: Compact hockey-puck footprint (approx. 58 × 45 × 25 mm class; refer to datasheet for exact mechanical drawing)

Terminals/Pin configuration: 4 screw terminals

- 2 for AC load (L/T) and 2 for DC control (+/-)

- Accept ring/fork lugs; torque specs provided in datasheet

Thermal characteristics: Must be mounted to an appropriate heat sink; use thermal grease or pad; follow derating curves vs. ambient and case temperature; airflow improves performance

Electrical properties (typical of the series; check datasheet for exact values):

- Input control: 3–32 VDC, low input current; LED/optically isolated

- Output: 24–280 VAC, zero-cross turn-on

- On-state voltage drop typically around 1–2 V at rated current

- Off-state leakage typical in mA range due to snubber

- High dv/dt immunity; dielectric isolation in kV range

Lifecycle

Status: Active and widely used; not nearing discontinuation based on current market availability

Equivalent and alternative models:

- Same family, different current ratings (use when your load is lower):

- Crydom D2425 (25 A, 24–280 VAC, zero-cross)

- Crydom D2430 (30 A, 24–280 VAC, zero-cross)

- Crydom D2440 (40 A, 24–280 VAC, zero-cross)

- Same function, random-turn alternative (use when you need switching at any phase angle):

- Crydom D2450R (24–280 VAC, 50 A, random turn-on)

- Cross-brand, close spec alternatives (verify mechanical and electrical fit via datasheets):

- Opto 22 240D50 (24–280 VAC, 50 A, DC input, zero-cross)

- Carlo Gavazzi RM1A48D50 (24–600 VAC, 50 A, DC input, zero-cross)
