SXC-SK01-C8A1 — 1–40 Channel Online Controller

SXC-SK01-C8A1 Pulse Controller

The upgraded successor to the classic SXC-X8A1: the same enclosure and mounting dimensions, much wider timing ranges, dual AC220V/DC24V power input, and on-site jog debugging — microprocessor pulse-jet control with strong interference immunity for baghouse dust collectors.

Product Q&A

Is the SXC-SK01-C8A1 a drop-in replacement for the SXC-X8A1 pulse controller?

Yes. The SXC-SK01-C8A1 was engineered as the direct successor to the SXC-X8A1 after some of the older model’s electronic components reached end of life. It uses the same enclosure and mounting dimensions, supports every X8A1 function, and fits an existing installation without rework.

Product Q&A

How do I read Xiechang pulse-controller model numbers such as SXC-SK01-C8A9-D32L-P?

SXC is the Xiechang controller prefix. SK = transparent PC plastic shell, JK = metal enclosure. C8Ax/C8Bx/C5A1 identifies the electronics platform. The tail encodes channels: 205L = 20 pulse + 5 lift valves, D32L/D36L = 32/36 freely-allocated channels, plain -10/20/30/40L = pulse-valve count. A final -P means a built-in differential-pressure sensor is fitted, -M means without; FB marks explosion-proof models.

Product Q&A

Which Xiechang pulse controller should I choose for my dust collector?

For small collectors up to 8 valves choose the SXC-C5A1-8; for standard online cleaning up to 40 valves the SXC-SK01-C8A1; for offline cleaning with lift valves the SXC-SK01-C8A8-205L (20+5), C8A9-D32L (32 channels, built-in ΔP option, Modbus) or JK01-C8B2-D36L (36 channels, aluminium shell, 6 digital inputs, master–slave); for ΔP-integrated control in one box the SXC-X8A5 or X8A7; and for explosion-proof areas the SXC-X8A4-FB or SXC-FB-40.

Advantages

How are Xiechang pulse controllers tested for reliability before release?

Type testing covers supply extremes (AC175–185V and AC240–250V), output short-circuit protection, double-coil load per channel, 120-hour continuous runs at both −30°C and +70°C, 2-hour 30 Hz vibration, packaged 2-metre drop tests, pulse-width accuracy checks at 100/150/200 ms, and communication tests including 120 m cable runs and 20 controllers on one PLC.
