Standard Signal 3-Way Isolating Amplifier
04/2005Data Sheet
Functions Features
The standard signal 3-way isolating amplifier MINI MCR-SL-I-I(-SP) / MINI MCR-SL-U-U(-SP) is used to electrically isolate, condition, amplify, and standard normalized signals. On the input and output side, the analog standard sig- nals 0...20 m A or 4...20 m A (MINI MCR-SL-I-I(-SP)), or 0...10 V or ±10 V (MINI MCR-SL-U-U(-SP)) are available, electrically isolated. The voltage supply (19.2...30 V DC) can either be pro- vided via connecting terminal blocks "3"/"4" or "7"/"8" of the modules, or together, via the DIN rail connector (see Figure 5 on page 6). Please also observe "Power Supply" on page 7.

Frequently Asked Questions
How should I power the MINI MCR-SL unit?
Never connect the supply voltage directly to the DIN rail connector; use a specific terminal block or system power supply.
What are the supported signal ranges for different models?
The MINI MCR-SL-I-I(-SP) supports 0...20 mA / 4...20 mA, while the MINI MCR-SL-U-U(-SP) handles 0...10 V or ±10 V.
What are the mandatory safety considerations for installation?
This equipment is suitable only for use in Class I, Division 2, Groups A, B, C and D or non-hazardous locations.
Is a fuse required when setting up the power supply?
Yes, it is recommended to connect a 2 A fuse upstream before powering the unit.
