MINI MCR-SL-I-I(-SP) and MINI MCR-SL-U-U(-SP) are three-way isolating amplifiers that are used to electrically isolate, condition, amplify, and standard normalize analog standard signals (0.20 mA or 4.20 mA (MINI MCR-SL-I-I(-SP)), or 0.10 V or ±10 V (MINI MCR-SL-U-U(-SP)).
The MINI MCR‑SL‑I‑I(-SP) and MINI MCR‑SL‑U‑U(-SP) are standard signal 3‑way isolating amplifiers that electrically isolate, condition, and amplify analog standard signals (0…20 mA or 4…20 V). Input and output ranges, ripple limits, and load specifications are listed, and the modules are designed for hazardous‑area use (Class | Division 2, Groups A‑D).
Power can be supplied via terminal blocks or a DIN‑rail connector (ME 6,2 TBUS‑2). The document details recommended fuse sizes, mounting instructions, and safety notes such as the requirement for qualified personnel and IP54 housing for installation in hazardous zones.
