●
In addition to the standard connectors on the Sampler, connections are
available that provide additional optional data I/O capabilities.
●
I/O connector with Power Fail Relay, 16 Digital Inputs, and 6 Analog
Voltage Outputs.
The I/O expansion board connects to the motherboard and adds the
capability to input external analog voltage signals and to output analog
currents via a connector located on the rear panel of the instrument. It
contains local power supplies, a DC/DC isolator supply, a sub-processor,
and analog circuits. Eight analog voltage inputs are provided with an input
voltage range of 0V to10 VDC. Six current outputs are provided with a
normal operating range of 0 to 20 mA. Current outputs may also be
configured for a 4 to 20 mA range through the Sampler firmware.
Internal connectors include:
●
Function key panel and Display
●
Measurement Interface Board Data
●
I/O Expansion Board Data
●
Digital Output Board
●
AC distribution
The digital output board connects to the motherboard and provides
solenoid driver outputs and relay contact outputs to a connector located on
the rear panel of the instrument. Ten relay contacts, normally open (with
power off), are provided which are electrically isolated from each other.
Eight solenoid driver outputs (open collector) are provided along with a
corresp24 VDC supply pin on the connector.
External I/O is driven from a generic bus that is capable of controlling the
following devices:
●
Analog output (voltage and current)
●
Analog input (voltage)
●
Digital output (TTL levels)
●
Digital input (TTL levels)
Note
The sampler has spare solenoid valve drivers and I/O support for
future expansion.
