SAFETY AND WARNING
- As MAS-DI-16-D with front panel potentiometer calibration, must not be exposed to heavy shocks or vibration which may cause SCM to get out of calibration.
- To avoid Electrostatic Discharge (ESD) to the SCM, which may cause permanent damage, always ground yourself by touching some grounded equipment.
- Before installation or beginning of any troubleshooting procedures the power to all equipment must be switched off and isolated. Units suspected of being faulty must be disconnected and removed first and brought to a properly equipped workshop for testing and repair.
- Component replacement and internal adjustments must be made by a company person only. Wiring must be carried out by personnel, who have basic electrical knowledge and practical experience.
- All wiring must conform to the appropriate standards of good practice and local codes and regulations. Wiring must be suitable for the voltage, current, and temperature rating of the system. Beware not to over-tighten the terminal screws.
CONNECTION
- Connect rated power at the terminal where 24VDC+ & 24VDC- are described in the wiring diagram.
- Field Input/Output Terminals:
Connect input between terminal where Input+ & Input- for particular channel for Input & take output from a 25-pin D-type PCB mounted male connector or from terminal where Output+ & Output- described in Connection Details.

BLOCK DIAGRAM
INSTALLATION
Mounting:
- Place the module with the DIN rail guide way on the bottom edge of the DIN rail and then snap it downwards.
- The housing is mounted on the DIN rail by swiveling it into place.
- The Horizontal mounting arrangement Shown here, allows good vertical air circulation. It is also recommended to keep adequate gap between two SCM.
Removal:
Release the snap-on catch using a screwdriver and then detach the module from the bottom edge of the DIN Rail.
