Aalborg PSV-D - Manual (Page 7)

Always make sure that only one jumper is ever applied at any given time to either
position 4 or 5. Connecting both at the same time may result in damage to the
electronics, and improper control.
b.1.4 Power Connection
With the DC power supply source OFF, connect the power to the DC power jack
OR the 9 pin "D" connector.
DO NOT CONNECT POWER TO BOTH CONNECTION POINTS AT
THE SAME TIME. This may result in permanent damage to the power
supplies and the PSV-D.
(c) DESCRIPTION
The PSV-D solenoid driver module is designed to regulate the power supplied to
the proportional solenoid valve (PSV) based on a reference signal. A 0 to 5 VDC
or 4 to 20 mA analog set point signal input is used as a reference to proportion-
ally control the output power to the PSV valve. By increasing or decreasing this
analog reference signal, the PSV valve volume of gases or liquids processed
increases or decreases respectively.
(d) SPECIFICATIONS
Environmental (per IEC 664): Installation Level II; Pollution Degree II.
Connection: 9 pin male "D" connector for input/output signals.
Power Input: +12 to 30 VDC; 1A @ 12 VDC, 0.5A @ 24 VDC via 9 pin "D" connector or DC
power jack (center positive).
Input Signal: AUTO SELECT feature allows circuit to recognize which analog input refer-
ence (0 to 5 VDC or 4 to 20 mA) signal is received.
For optional RS232 or IEEE488 interfaces please contact your distributor or Aalborg.
TTL ON/OFF: Jumper selectable LOW (0 VDC) OFF – HIGH (5 VDC) ON [default setting]
or reverse, to select valve ON/OFF status.
Valve Output Power: Jumper selectable to +15, +22, and +29 VDC with adjacent poten-
tiometer to obtain +2 VDC [default setting 22 VDC].
Fuse Rating: internal resettable 1.6A fuse protects the electronics on the power input.
Polarity Protection: internal rectifier circuit protects from reversed polarity on the power
input.
Operating Temperature: 0 F C (32 F F) to 50 F F (122 F F).
