analyzer card.
Analog Output terminal strip
The 2-point analog output terminal strip (terminals 8 and 9) is directly above the detector terminal strip. You
connect wiring from a recording device (if applicable) to the analog output terminal strip. The output at the
analog output terminal strip is 4 to 20 mA or 0 to 1 V. The output is selectable by jumpers on the analyzer
card. The standard (default) output is 4 to 20 mA.
External alarms terminal strip
N O T E
:
The Pioneer-16R also includes a common external alarm terminal strip (on the Power I/O card).
The common terminal strip activates external alarms for all active channels.
The 9-point external alarm terminal strip is above the analog output terminal strip. You connect wiring from
external alarms (if applicable) to the external alarm terminal strip. This terminal strip has common (C),
normally closed (NC), and normally open (NO) terminals for alarm 1, alarm 2, and alarm 3 connections.
Pilot Light
The pilot light is between the external alarms terminal strip and analog output terminal strip. The pilot light
flashes when the analyzer card is receiving power and operating normally. The pilot light does not flash or
is off when a failure occurs.
Relays
NOTE
:
The Pioneer-16R also includes four common relays (on the Power I/O card). The common
relays activate for
all
active channels.
Three relays are behind the external alarm terminal strip. The relays are single-pole, double-throw (SPDT)
and are rated for 8 amps at 250 VAC (resistive). The relays are from top to bottom alarm 1, alarm 2, and
alarm 3. The relays are dedicated to the channel that the analyzer card is plugged into only. For example,
the alarm 1 relay energizes only when the channel that the card is plugged into goes into an alarm 1
condition.
N O T E
:
You can select normally energized or normally de-energized relays in the Instrument Setup
program. This section describes the default setting: normally de-energized.
