PK2100
3-4 s I/O Configurations
3 One high-sensitivity differential analog input. Normally, the
high-sensitivity range is 01 volts, but the input gain can be changed
by installing different input resistors on the operational amplifier.
When the positive side of the differential input is more than 1volt, its
voltage can be measured by the universal input with which it is
coupled. This input is suitable for connection to resistance bridges.
4. Two relay-contact outputs (NO, NC, COM for each relay). The relays
are rated for 3amps at 48volts. Contact-protection devices may be
installed.
5. Ten high-current outputs suitable for driving relays, stepping motors,
or solenoids. These outputs can sink approximately 300milliamps
each at up to 48volts, subject to total heat dissipation restrictions for
the integrated-circuit driver.
6. One analog output (DAC), which may be a voltage output (010volts
for PK2100/PK2120 and 07 volts for PK2110/PK2130) or a current
output (020mA for PK2100/PK2120 and 015 mA for PK2110/
PK2130). A second analog voltage output (UEXP) is available when
the universal inputs are used as fixed-threshold digital inputs.
7 Communication interfaces including a full-duplex RS-422/RS-485
serial port that can operate asynchronously at up to 38,400 baud, and
an RS-232 serial port with two handshaking lines that can operate at
up to 38,400 baud. A second RS-232 port can be configured as a
substitute for the RS-422/RS-485 port by changing board jumpers, but
it will have no handshaking lines. There is also a 26-pin connector to
Z-Worlds PLCBus expansion bus for customer-designed devices or
Z-World PLCBus expansion devices.
Universal Inputs
The universal interface comprises six analog inputs (U1U6) with a
measurement range of 010 volts (07volts for PK2110/PK2130). An
additional universal input channel (A/D+) is available when it is not in use
as part of the high-gain input.
A universal input may be read either as an analog input (by taking an
analog reading) or as a digital input by comparing the voltage at the input
with a threshold. Software provided by Z-World can be used to compare
the input voltage to a single fixed threshold or to two software-specified
thresholds.
Single Threshold. A digital 1 results when the voltage is above the
threshold. Otherwise a digital 0 results.
Dual Threshold. A digital 1 results when the voltage is above the high
threshold. A digital 0 results when the voltage is below the low
threshold. Otherwise, the software reports no change. Z-Worlds virtual
