Description

The IMDSM05 consists of a single printed circuit board that occupies one slot in a Module Mounting Unit (MMU). It monitors eight digital inputs and eight digital outputs. Twelve I/O circuits are isolated from each other; the remaining two pairs share common positive input lines. Two captive screws on the module faceplate secure it to the MMU. Sixteen front panel LED status indicators (group A and group B) display the input and output status. The slave module has three card edge connectors for external signals and power. P1 connects to common (ground) and +5 VDC power. P2 connects the module to the slave expander bus to communicate with an MFP/LMM master module. Connector carries digital signals to a Termination Unit (TU) (refer to Table 5-3). The terminal blocks (physical connection points) for field wiring are on the TU.

Applications

Power and energy plants: Used to monitor the status feedback of circuit breakers and disconnectors, and to control the start and stop of auxiliary equipment.

Oil and chemical plants: Used in oil and gas processing stations or chemical plants to control the switching logic of solenoid valves and pumps, and to monitor field instrument alarm points.

Metallurgical and metal processing plants: In steel rolling mills or smelting workshops, responsible for monitoring position sensors of conveying equipment and simple pneumatic/hydraulic actuators.

Paper and pulp plants: Used to monitor limit switches and material status feedback on production lines.

Water treatment and municipal facilities: In large water supply or sewage treatment plants, to control water pump switching and monitor flow meter alarms.

FEATURES

The modular design of the DSM, as with all Infi 90 modules, allows for flexibility when you are creating a process management system strategy. It is capable of bringing sixteen separate digital signals (24 VDC) into/out of the system.

Multi-Function Processor and Logic Master Module interface to the IMDSM05 on the slave expander bus. The DSM is a high power slave. You can use up to 20 high power slaves on any master (MFP/LMM) slave expander bus.

Individual jumpers on the DSM module configure each of the I/O circuits as inputs/outputs for non-isolated operation with read-back capabilities, or two-wire isolated outputs without read-back capabilities.

The front panel LED status indicators provide a visual indication of the input states to aid in system test and diagnosis. A DSM can be removed or installed without powering the system down.

SPECIAL HANDLING

The Digital Slave Module (DSM) uses electrostatic sensitive

devices. Follow Steps 1 through 4 when handling:

1. Keep the module in its special anti-static bag until you are

ready to install it in the system. Save the bag for future use.

2. Ground the anti-static bag before opening.

3. Verify that all devices connected to the module are properly

grounded before using them.

4. Avoid touching the circuitry when handling the module

REPAIR/REPLACEMENT

If you determine the DSM is faulty, replace it with a new one. DO NOT try to repair the module; replacing components may affect the module performance. You can remove the module while system power is supplied.

To replace a module:

1. Push and turn the two front panel captive retaining screws one half turn to unlatch the module. It is unlatched when the slots on the screws are vertical and the open end of the slots face away from the module.

2. Gently slide the module out of the MMU.

3. Configure the replacement module switch and jumper settings. Ensure they are set the same as the original module.

4. In the same slot assignment as the original module, align the replacement module with the plastic guide rails in the MMU. Gently slide it in until the front panel is flush with the top and bottom of the MMU frame.

5. Push and turn the two captive retaining screws on the module faceplate one half turn to the latched position. It is latched when the slots on the screws are vertical and the open ends face the center of the module. (To remove the module, turn the module retaining screws to the unlatched position and gently slide out).

6. Return to normal operation.
