Product Description P/N: DC21-60C0-S000
Description
The Watlow DC21-60C0-S000 is a solid-state power controller for switching three-phase industrial heater loads through two controlled supply legs. It combines zero-cross contactor operation with forced-air cooling and a shorted silicon-controlled rectifier alarm for identifying an output fault.

Information About DC21-60C0-S000
The DC21-60C0-S000 is a DIN-A-MITE Style C assembly containing four silicon-controlled rectifiers and an integrated heat sink. Its control interface accepts a 4.5–32-volt direct current command from compatible temperature controllers or other switching sources. A separately powered 120-volt alternating current fan supports heat removal during operation. The unit mounts on a DIN rail or panel and includes the shorted-output alarm configuration identified by its S000 suffix.
Key Features:
- Two-Leg Power Switching: Controls two conductors of a compatible three-phase heater supply.
- Zero-Cross Operation: Switches near the alternating current voltage zero crossing in response to an on/off command.
- Direct Current Input: Accepts a 4.5–32-volt command signal from compatible external equipment.
- Shorted Output Alarm: Provides fault indication for a shorted silicon-controlled rectifier condition.
- Semiconductor Construction: Uses four power switching devices without mechanical load-switching contacts.
- Fan-Assisted Cooling: Combines an integrated heat sink with a 120-volt alternating current cooling fan.
- Installation Options: Supports standard DIN-rail attachment or direct panel mounting.
The DC21-60C0-S000 delivers the reliability and precision required for heater power switching and output fault monitoring in industrial thermal equipment.
