The back panel of the transmitter housing has two 32-pin connectors,
labeled CN1 and CN2, and a 2-pin connector, labeled CN3. Mating
terminal strips, shipped with the transmitter, plug into the connectors.
The detachable terminal strips enable wiring to remain connected when
the transmitter is removed from the rack.
• AC power-supply wiring connects to CN3
• DC power-supply wiring connects to CN2
• Sensor wiring connects to CN1
• Output wiring connects to CN2
Connectors CN1 and CN2 are available in two types, illustrated in
Figure 3-4
, page 15.
• The standard rectangular configuration accommodates fast-on (wire-
pin) or soldered connections.
• The optional Y-shaped connectors have screw terminals, which
accommodate wires as large as 14 AWG (2.5 mm²).
• For fast-on/solder connectors, on connector CN1, pin row D is not
used; on connector CN2, pin row B is not used.
Connectors CN1 and CN2 meet DIN standard 41612, Model F (male).
