4.2 Supply via MINI MCR-2-PTB... power terminal

MINI MCR-2-PTB… power terminals are particularly suitable for supplying power to

MINI Analog Pro modules. They have the familiar 6.2 mm housing and can be seamlessly

integrated into the MINI Analog Pro range. Redundant supply is supported. The

decoupling of power supplies used for supply is ensured by the diodes integrated in the

module. Moreover, it is possible to extend mechanical redundancy by using two power

terminals. A 4 A fuse should be used to protect the power terminal(s). It is important to

make sure here that tripping is guaranteed in the event of a short circuit by the power

supply/supplies used. You can calculate the maximum number of modules, regardless of

whether you are using one or two MINI MCR-2-PTB… modules, with the aid of the product

documents using the formula below.

Recommended fuse for power terminal:

Fuse according to IEC 60127-2/V

Nominal current: 2.5 A

Characteristic: slow-blow

(e.g., Wickmann 5 x 20 mm/No. 195 - glass fuse)

4.2.1 MINI MCR-2-PTB... power terminal in combination with

intrinsically safe MINI Analog Pro versions

For direct connection of the MINI MCR-2-PTB... power terminal to the intrinsically safe

and functionally safe versions of the MINI Analog Pro product family, plug the blind plug

provided with the MINI MCR-2-PTB... power terminal into connector position 4

(terminal points 1/2 and 3/4) and 5 of the module. Thus, direct connection is possible.

4.2.2 Supply via a MINI MCR-2-PTB... power terminal

In the case of supply via the power terminal, all MINI Analog Pro modules connected via

the TBUS DIN rail connector are supplied. Both supply inputs can be supplied by one

power supply, see Figure 4-3 on page 29, or redundant supply by means of two different

power supplies is implemented, see Figure 4-4 on page 29. It is important here that both

supply circuits have separate protection. In this way, a maximum current of 3.2 A can be

fed into the DIN rail connector.

For intrinsically safe and functionally safe MINI Analog Pro versions, you must

observe Section 4.2.1.
