External Power to Termination:
3099/11-X00:
24 VDC nominal
Note:
The external Power Supply to the Termination Module
must
be fuse
protected not to exceed 30 A.
Power Requirements:
+5 VDC @ 500 mA
+24 VDC @ 150 mA
Termination Module Connectors:
One D-Sub connector, 37 pins for use with the 3057/00
Analog Cables. These cables have a diameter of 0.5 inches
(1.27 centimeters) with a minimum bend radius of 4.6 inches
(11.69 centimeters).
Field Wiring Mating Connector:
AMP (Tyco) 205209-2 37- Pin D-Sub Connector, Female
Termination Module:
All Termination Modules are 4.38 inches (11.1 centimeters)
in height and require a minimum depth of 3.75 inches (9.5
centimeters). The width for each termination module and the
compatible field wiring size is tabulated as following:

Effect of Incorrect Field Wiring:
Shorted connections produce zero analog input reading.
Open connections produce incorrect analog input reading in
voltage mode. In current mode, shorted connections will
produce zero analog input, which can be annunciated as
out-of-range in 4-20 mA configurations. Reverse
connections produce (sign) inverted analog input readings in
voltage mode. In current mode, reverse connections will
produce negative analog input reading, which can be
annunciated as out-of-range in the error status word.
