Table 3-1: Analog Output Connections Pin Function - Teledyne 2000RS Operating Instructions Manual

Installation
Analog Outputs: There are four DC output signal pins—two pins
per output. For polarity, see Table 3-1. The outputs are user selectable
(either 0-1 vdc or 4-20 ma) but must be selected from the system menu:
 0–1 VDC % of Range: Voltage rises linearly with increasing
 0–1 VDC Range ID:
 4–20 mA DC % Range: Current increases linearly with
 4–20 mA DC Range ID: 8 mA = Low Range, 12 mA = Medium

Alarm Relays: The nine alarm-circuit connector pins connect to
the internal alarm relay contacts. Each set of three pins provides one set
of Form C relay contacts. Each relay has both normally open and
normally closed contact connections. The contact connections are shown
in Table 3-2. The contacts are capable of switching up to 1 amp at 250 V
ac into a resistive load.
