STB ACO 0120 Field Wiring
Summary The STB ACO 0120 module uses one six-terminal field wiring connector. This
analog actuator is wired to the top connector.
Connector Types Use either:
z an STB XTS 1100 screw type field wiring connector (available in a kit of 20)
z an STB XTS 2100 spring clamp field wiring connector (available in a kit of 20)
The field wiring connector has six connection terminals, with a 3.8 mm (0.15 in)
pitch, between each pin.
Field Actuators The STB ACO 0120 module supports a one channel analog actuator. It handles
outputs in the range of 4 to 20 mA. Data on this channel has a resolution of 15 bit +
sign.
Field Wire
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 required to meet CE. (See the Advantys STB System
Planning and Installation Guide (890 USE 171) for an illustrated example of an
island segment with an EMC kit making the analog I/O modules CE compliant.) 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.
