Filters
When pressure drop is not a concern, use in-line sintered
filters to prevent large particulates from entering the flow
body of the controller. Suggested maximum particulate sizes
are as follows
Mass Flow:
• 5 microns
for devices with flow ranges ≤1 SCCM.
• 20 microns
for devices with flow ranges
between 1 SCCM and 1 SLPM.
• 50 microns
for devices with flow ranges ≥1 SLPM.
Liquid:
• 20 microns
for devices with flow ranges ≤100 CCM.
• 40 microns
for devices with flow ranges >100 CCM.
Pressure:
•
Maximum
40 microns
for all gauges.
• 20 microns
for PC, PCD, PCP, PCPD,
PCH, PCHD, PC3, PCD3
40 microns
for PCR, PCRD, PCR3, PCRD3
Power and Signal Connections
Power can be supplied to your device through either the
power jack or the multi-pin connector on top of your device.
For more pinout configurations, see
✓
Note:
Power requirements vary based on
analog configuration and valve type. Please
reference the associated specification sheet at
for power requirements.
⚠
Warning:
Do not connect power to pins 1
through 6, as permanent damage can occur. It
is common to mistake pin 2 (labeled 5.12 Vdc
Output) as the standard 0–5 Vdc analog output
signal. Pin 2 is normally a constant 5.12 Vdc.
