MINI MCR-SL-PT100-UI-200

Data sheet

INTERFACE

The MINI MCR-SL-PT100-UI-200... is a configurable 3-way

isolated temperature transducer. It is suitable for the connec-

tion of PT100 resistance thermometers according to IEC

60751 in 2-, 3-, and 4-wire connection methods. The measur-

ing range can be configured from -50°C to +200°C using a

DIP switch.

The standard analog signals 0...20 mA, 4...20 mA, 0...10 V,

0...5 V, 1...5 V, 10...0 V, 20...0 mA, 20...4 mA are available

electrically isolated on the output side.

The DIP switches are accessible on the side of the housing

and allow the following parameters to be configured:

– Connection method

– Temperature range to be measured

–Output signal

– Type of fault evaluation

The power supply (19.2...30 V DC) can be supplied either via

connection terminal blocks "7"/"8" on the modules or in con-

unction with the DIN rail connector. Please refer to the sec-

tion titled "Connection methods" for more information.

Features

– Configurable 3-way temperature transducer

– 2-, 3-, 4-conductor connection method for Pt 100 resis-

tance thermometer

– Measuring range 0°C to 200°C

– Increased accuracy due to smaller temperature measur-

ing range

– Output signal range 0...20 mA, 4...20 mA, 0...10 V, 0...5

V, 1...5 V,10...0 V, 20...0 mA or 20...4 mA

– Approval for Ex-zone 2 (nA)

– Screw or spring-cage connection can be provided

– Can be supplied configured to order or unconfigured

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-PT100-UI-200 7 Configuration NC version If a device has not been configured ("NC type": MINI MCRSL-PT100-UI-200-NC or MINI MCR-SL-PT100-UI-200-SPNC), all DIP switches will be set to position 0. The device only has a defined function once the DIP switches have been set. DIP switch S1 DIP switch S1 is used to specify the connection method, the output signal range, and the measuring range start value.
