STB ACO 1210 Field Wiring
Summary The STB ACO 1210 module uses two six-terminal field wiring connectors. Analog
actuator 1 is wired to the top connector, and the analog actuator 2 is wired to the
bottom connector. The choices of connectors and field wire types are described
below, and some field wiring options are presented.
Connector Types Use a set of either:
z two STB XTS 1100 screw type field wiring connectors (available in a kit of 20)
z two STB XTS 2100 spring clamp field wiring connectors (available in a kit of 20)
These field wiring connectors each have six connection terminals, with a 3.8 mm
(0.15 in) pitch between each pin.
Field Actuators The STB ACO 1210 module handles analog output data from two 0 ... 20 mA single-
ended analog field actuators. Data on each channel has a resolution of 12 bits. The
module is designed to support high duty cycles and to control continuous-operation
equipment.
The module allows you to connect to two-, three- and four-wire devices that can
draw current up to:
z 100 mA/channel at 30 degrees C
z 50 mA/channel at 60 degrees C
If you want to maintain the module’s built-in isolation between the analog portion of
the module and the island’s actuator bus, you can make connections only to a two-
wire device.
Field Wiring
Requirements
Individual connector terminals accept one field wire. Use wire sizes in the range
0.5...1.5mm
2
(24 ... 16 AWG).
Shielded twisted-pair wire is recommended. The shield should be tied to an external
clamp that is tied to functional earth.
We recommend that you strip at least 9 mm from the wire’s jacket for the module
connection.
Field
Wiring Pinouts
The top connector supports analog actuator 1, and the bottom connector supports
analog actuator 2. Four field wires may be used on each connector—on pins 1, 2, 4
and 6.
