LOGIC OUTPUT - PL330QMT & PL330TP
Output Voltage
Range:
4 to 6 Volts
Output Current:
0.1 to 7 Amps.
Output Switch:
Isolates the output and permits output voltage to be set bef-
ore connecting the load.

Clamped by the over-voltage protection circuit for forward
voltages over 7 Volts and up to 1 Amp forward current. Di-
ode clamped for reverse voltages and up to 3 Amps reverse
current.

PL-P MODELS,ADDITIONAL SPECIFICATIONS
Remote programmable versions in the range feature full control, read back and
status reporting via the GPIB and RS232 interfaces. The GPIB interface con-
forms to the IEEE 488.1 and 488.2 standards and the RS232 interface is fully
compatible with the Thurlby-Thandar Addressable RS232 Chain (ARC) standard.
8 rear panel DIP switches are used to specify baud rate, bus address and active
interface (GPIB or RS232). Remote/Local operation is selected by a front panel
switch.
LOCAL OPERATION
For a programmable instrument operated in local state, all capabilities and speci-
fications remain unchanged from those of a standard instrument .
REMOTE OPERATION
With the instrument switched to the remote state, all voltage and current adjust-
ment controls become inoperative and commands received over the active inter-
face will be parsed and executed.

REMOTE CONTROL INTERFACES - PL-P MODELS
Both interfaces feature full control, readback and status reporting.
RS232:
Variable Baud rate (9600 maximum), 9 pin D-connector (fe-
male). Fully compatible with ARC (Addressable RS232
Chain) system.
GPIB:
Conforming with IEEE-488.1 and IEEE-488.2
Address Selection:
By rear panel DIP switch.
Remote/Local
Operation:
Selected by front panel switch.
Remote Command Response Time:
Interface:
<15ms(singlecommand,inputbufferempty).
Output Voltage - Up:Time constant typically 2ms, e.g. 10ms to settle within 1%
of a step change, 15ms to settle within 0.1%.
OutputVoltage-DoTime constant determined by the discharge of the power
supply output capacitor (47uF). Typically <10ms to settle
within 1% for a 10V step change at 50mA load current; typi-
cally <200ms to settle within 1% at zero load.
Output Current:
Typically 50ms to settle within 10mA for a 1A change.
