Data sheet

INTERFACE

The 6.2 mm wide MINI MCR-SL-R-UI... potiposition trans-

ducer converts potentiometer positions as a percentage of an

standard analog signal. If the potentiometer range cannot be

utilized to the full, an externally accessible slide switch is used

to set the upper and lower potiposition end values. The output

signal between 0 and 100% is based on this fixed end value.

The DIP switches are accessible on the side of the housing

and allow the following parameters to be configured:

– output signal,

– automatic potentiometer detection,

– open circuit detection loop as well as

– error indication type.

Power (19.2 V DC to 30 V DC) can be supplied through con-

nection terminal blocks on the modules or in conjunction with

the DIN rail connector.

Features

– Configurable potipostion transducer

– Output signal range can be configured using a DIP switch

– Approval for Ex-zone 2 (nA)

– Screw or spring-cage connection can be provided

Attention: Correct usage in potentially explosive areas

The module is a category 3 item of electrical equipment. It is absolutely vital to follow the instructions provided

here during installation and observe the information in the "Safety regulations and installation notes".

Make sure you always use the latest documentation.

MINI MCR-SL-R-UI... 7 Configuration If the modules are not configured (all DIP switches set to position 0), the module does not have a defined function until the DIP switches have been set. The output signal range, potentiometer/open circuit detection and fault evaluation is specified by the SP1 DIP switch. Activate automatic potentiometer detection to obtain optimum measurement results. You can use the S2 DIP switch to select the voltage and current output. www.interface.phoenixcontact.
