Mecair IS-ACDC40-PCA Sequencer

IS/ISP SERIES IS/ISP SEQUENCER DESCRIPTION The IS/ISP Sequencer features integrated controls intended for use with larger reverse
pulse jet filter cleaning systems. The IS & ISP have been designed to operate across a wide
range of environmental conditions. It is suitable for use with all types of filters, including
bags, cartridges, sintered metal or ceramic filters.
The IS sequencer operates in continuous mode, whereas the ISP has a built-in differential
pressure sensor, allowing this sequencer to be demand driven. IS & ISP may be ordered as
the sequencer only or in an enclosure (polycarbonate).
FEATURES
• Low temperature operation −40°C (−40°F)
• Automatic valve detection.
• Voltage-free coil error output and a visual indication on the display showing which pilot
valve output has an error, enabling quick fault finding and debugging.
• Conforms to the requirements of CE, FCC, RCM, cURus, cULus, & ATEX.
