Acramatic I/O Module List

Cincinnati Milacron designed a wide variety of I/O modules to fit the “Acramatic 850″ MIA (Machine Interface Assembly) racks.

We’ve never found a list of known Cincinnati part numbers, so maybe you will find this a handy reference.


The most common modules are being used to test M2MT for Phase 1…

Basic Digital I/O

  • 3-531-3891A DCI : DC digital input (24 Vdc x 8 ch)
  • 3-531-3972A DCO: DC digital output (24 Vdc transistor x 8 ch)
  • 3-531-3855A ACI: AC digital input (120Vac x 8 ch)
  • 3-531-3839A ACO: AC digital output (120Vac triac x 8 ch)

We haven’t tested the following modules yet, but they will probably work…

  • 3-531-3878A TCM: RELAY CONTACTS OUT (8 ch)
  • 3-531-4416A PIO Rev. A Probe Interface

M2MT hardware is designed to support other I/O types. This might be part of Phase 2, and depends on whether we see any interest…

Analog I/O

  • 3-531-3957A Thermocouple Interface
  • 3-531-3915A Analog-Digital Converter
  • 3-531-4075A Digital-Analog Converter

M2MT is unlikely to support the following less common modules, as there are probably better ways to implement these interfaces.

User Interface Expansion

  • 3-531-3973A CRT Module
  • 3-531-4000A KEYBOARD INTERFACE

Communications

  • 3-531-4267A IBA: I/O Bus Assembly (M2MT makes this module obsolete!)
  • 3-531-4189A Register Serial
  • 3-531-4306A Communication Module Board

Miscellaneous

  • 3-531-4237A Bulk Data Storage Module
  • 3-531-4229 UNIVERSAL POWER CONNECTOR
  • 3-531-3911A – DC Motor Module

These are all the modules we know about! If we’ve missed anything, please let us know.
