In the event of a supply voltage below 18 V DC, the number of modules is reduced according to the increasing current flow. Up to 40 MINI Analog modules are supplied at a supply voltage of 12 V DC (50 mA per device). NOTE The total current in both supply paths must not exceed 2 A. Connect at least one supply to the power terminal in order to supply the DIN rail connector. • Wire the second input to provide redundancy. PHOENIX CONTACT 6 MINI MCR-SL-PTB-FM For additional mechanical redundancy, two power terminals and two fault monitoring modules can be used. Only one supply may be connected to each power terminal. In the second fault monitoring module, fault monitoring of external measuring transducers must be deactivated because evaluation can only take place via a module in a group. 6.6 6.7 Connecting the wires The module is available in two connection versions: – Screw terminal blocks (for MINI MCR-SL-PTB-FM) – Spring-cage terminal blocks (for MINI MCR-SL-PTB-FMSP) Screw connection: B Assembly B A www.interface.phoenixcontact.com A C D E Figure 4 • • X XXX XXX o.

It is used to bridge the power supply. It is also absolutely vital that you snap the module and the DIN rail connector into position in the correct direction: the snap-on foot should be at the bottom and the connector on the left. www.interface.phoenixcontact.com – Mounting and removing Figure 5 • • 105449_en_00 X XXX XXX o.

PHOENIX CONTACT 7 MINI MCR-SL-PTB-FM 7 Fault monitoring FM 8 Fault monitoring simplifies error evaluation in multi-channel – isolation amplifier applications using a group error message. – 7.1 Fault monitoring for group error detection • • Use MINI Analog signal conditioners that support fault monitoring. Connect these signal conditioners to the MINI MCR-SLFM-RC(-SP)-NC fault monitoring module via the DIN rail connector . Diagnostic indicator The green LEDs on the front indicate that the relevant supply voltages are present on the DIN rail connector. Red LEDs light up when supply voltages are connected to the wrong poles. In the case of a correctly connected supply voltage, the red LED goes out. Detected errors on the signal input of a MINI Analog isolation amplifier or in the isolation amplifier are reported to the fault monitoring module via the DIN rail connector. The module reports the error centrally via an N/C contact. 7.2 Fault monitoring for redundancy monitoring With "supply via power terminal", the fault monitoring module can be used to monitor the supply voltage in the group. Failure of the supply voltage generates a central message via an N/C contact. • Install a power terminal and a fault monitoring module of the same shape side-by-side without spacing. • Bridge terminals 1 to 4 of the power terminal with terminals 1 to 4 of the fault monitoring module. Use the provided plug-in bridges FB S2-6 (Order No. 3030336) or normal cables. 105449_en_00 PHOENIX CONTACT GmbH & Co. KG • 32823 Blomberg • Germany www.phoenixcontact.com 8
