1141 and 1142, Manual
One and Two Channel 1762 I/O Resolver Interface Modules
Revision 2.0
Module Overview
Utilizing licensed Allen-Bradley interface technology, these Resolver Interface Modules can be added as
expansion modules to Rockwell Automation’s MicroLogix 1100, 1200, and 1400 rack systems.
The 1141 is a one channel module that can be connected to one resolver, and the 1142 is a two channel
module that can be connected to either two independent single resolver transducers or a single dual resolver
transducer.
Both the 1141 and 1142 modules have an input that can be configured for stop time monitoring (channel 1
only), to capture the current position, or to offset the current position to a previously programmed preset value
(channel 1 only). This input will operate at either at 24Vdc or 120Vac.
These modules have the additional ability to be programmed to interface to Autotech and standard Gemco
resolvers that have a transformation ratio of 1.4.
Prior to serial number 03180001, only the now obsolete 1141A and 1142A
modules could be programmed to be compatible with resolvers that have a
transformation ratio of 1.4.

Chapter 1: Installing the 114X module
WARNING Disconnect power before attempting to install or remove the 114X module.
Chapter 1: Installing the 114X module
1. Verify that your system’s power supply has adequate reserve current capacity. The 114X module
requires 45mA at +5Vdc and 48mA @24Vdc.
2. The 114X module is not hot swap capable, power must be removed before removing or installing any
module.
3. The 114X can be mounted on the following DIN Rails
EN 05 022 – 35 X 7.5 (35 X 7.5 mm)
EN 05 022 – 35 X 15 (35 X 15 mm)
4. Close the DIN rail latch on the module before mounting the module on the rail.
5. Press the DIN rail mounting area of the module against the rail. The latch will open as you install the
module and will snap into place when the module is properly seated on the DIN rail.
6. The communication bus is carried between the modules through the ribbon cable attached to every
module.
7. If necessary, remove the bus connector cover from the PLC and or from the module that the 114X
will be connected to.
8. Use the pull loop on the connector to plug the ribbon cable from the 114X into either the module or
the PLC directly to the left of 114X module.
9. Reinstall the bus connector cover.
10. It is very important to use the pull loop to disconnect modules. Pulling on the ribbon cable may
damage the cable or the module.
Disconnect power before attempting to install or remove the

Input
The two Input terminals accept a 24Vdc or a 120Vac signal across the two terminals. The input is
bipolar, that is, positive voltage can be applied to either pin. The input function is programmable and can
be selected to monitor the stopping time and brake applied position of channel 1, to capture the current
position, or to apply the preset of channel 1.
The input can be programmed to act on either the ON to OFF (power removed) or the OFF to ON (power
applied) transition of the input, with the default being the ON to OFF transition.
DC AC
On State 10 to 30Vdc 79 to 132Vac
Off State 0 to 2Vdc 0 to 2Vac
Current Draw 5mA @ 24Vdc 10mArms @ 120Vac
Pre made cables are available from AMCI. These cables come with a Bendix connector that mate with the
resolver transducer. The other end is pigtailed at the factory for easy connection to the 114X module’s
connector. These cables have a part number of CTL-X for single resolver transducers and CML-X for the
dual resolver transducers. In both cases, X equals the length in feet. The maximum CTL-X cable length is
500 feet.
The CTL-X cable shown below is used to connect an AMCI single resolver transducer to the 114X module.
Two of these cables will be needed to connect two AMCI resolvers to the 1142 module configured to use two
single resolver transducers.
If the input has been configured to Apply the Preset to the channel 1
position, each inactive to active transition of the input will count as one of
the EEPROM’s 100,000 write cycles.

One and Two Channel 1762 I/O Resolver Interface Modules
Revision 2.0
The CML-X cable shown below is used to connect an AMCI Dual Resolver transducer to the 1142 module.
Wiring Notes:
•AMCI recommends the use of either the Beldin 9873 or 9730 or equivalent cables to connect the
single resolver transducers to the 114X module. While the Beldin 9730 can be used for cable runs of
between 1 and 500 feet, the 9873 can only be used for runs of less than 100 feet.
•Resolver signals are low voltage, low power signals. If you are using A-B guidelines for cabling
installation, treat the cable as a Category 2 cable. It can be installed in conduit along with other low
power cabling such as communication cables and low power ac/dc I/O lines. It cannot be installed in
conduit with ac power lines or high power ac/dc I/O lines.
•Like all signal and communication cable, the resolver cable should be shielded. These shields must be
grounded only at one end of the cable. Because the control cabinet is typically better grounded than
the machine, AMCI recommends that you attach the shields at the module end of the cable run.
•Shield pin 8 IS NOT connected to either the 114X module or to earth ground and is included as a
convenient place to land the shield wires. To drain the electronic noise away, a heavy wire MUST
ALSO BE RUN from the pin 8 to your earth ground bus.
•Treat the shields as conductors at any junctions. Do not ground the shields at the junction box.
•If the resolver cable must cross power feed lines, it should do so at right angles.
•Route the cable at least five feet from high voltage enclosures, or sources of “rf” radiation.
