Input Voltage Configuration
See “sMI6 Digital Input Logic Voltage Configuration” on page 21.
Output Current Requirements (MP6-M, HPE and BR, External)
The digital outputs (HPE and BR) on the MP6-M are optically-isolated via Opto-22
modules. (Therefore, the output specifications for the MP6-M are different than the
MP6-S.) Select an appropriate plug-in single-channel module from the “Generation 4”
(G4) range manufactured by Opto-22. (Compatible modules are also made by other
manufacturers.)
Modules are available for various external voltages to suit the user’s equipment,
including 12V DC and 24V DC, and 110VAC and 230VAC. See Table 2-3 for specifications
of some commonly-used modules. (See the manufacturer’s documentation for any
parameters or module types not listed.) You must provide logic-power to connect to and
from the Opto-22 modules. The logic input current required depends on the number,
voltage, and type of Opto-22 modules.
The Opto-22 DC output modules can each supply from 0.5 to 3 Amps to the user’s
external equipment. The total current actually required for outputs will depend on the
user-supplied external equipment (relays, solenoids, limit switches, etc.).
User-Supplied Logic Power (Internal)
The Opto-22 opto-isolator modules also require logic voltage to interface with the Adept
sMI6 module. This voltage must be provided by the user at the PWR terminals. The power
supply voltage should be the same as the logic voltage rating of the Opto 22 output
module. For example: 5V logic voltage Opto 22 requires a 5V logic user-supplied power
supply. Use of shielded, twisted-pair cable is recommended. Allow 12mA per output
channel (a total 0.1A for 7 modules) for each MP6-M.
