Product Q&A

What monitoring and control features distinguish the SXC-X8A7 pulse controller?

The SXC-X8A7 offers four trigger modes (timed, ΔP, mixed ΔP+timed fallback, and external dry contact), a built-in ΔP sensor with 4–20 mA retransmission to PLC or panel meters, ΔP high/low alarm contacts with hysteresis, and a unique un-fired-valve query that uses an air-tank pressure contact to flag valves that did not actually pulse.

Product Q&A

What trigger modes do pulse controllers offer — timed, differential-pressure, mixed and external?

Four modes are common across the Xiechang range: timed sequential cleaning at fixed intervals; differential-pressure triggering, which starts a cleaning cycle only when filter ΔP crosses a set value (from a dry contact or a built-in sensor); mixed mode, which is ΔP-led but guarantees a cleaning cycle after a set maximum time; and external triggering from a remote dry contact (PLC or push-button).
