Optional remote modules Description PE50243 DSM303 remote advanced UMI module The DSM303 module provides the same functional features as the fixed advanced UMI. Associated with a Sepam with a basic UMI, it may be installed on the front panel of the cubicle in the most suitable operating location. b reduced depth of 30 mm b a single module for each Sepam with a basic UMI, to be connected by one of the CCA772 or CCA774 prefabricated cords (2 or 4 meters). This module may not be connected to Sepam units with integrated advanced UMIs. DSM303 remote advanced UMI module. MT11009 MSA141 analog output module The MSA141 module converts Sepam measurements into analog signals. b selection of the measurement to be converted by parameter setting b 0-10 mA, 4-20 mA or 0-20 mA analog signal according to parameter setting b connection of the analog output to a screw-type connector: v 1 wire with cross-section 0.2 to 2.5 mm² (u AWG 24-12) v or 2 wires with cross-section 0.2 to 1 mm² (u AWG 24-16) b a single module for each Sepam base unit, to be connected to one of the CCA770, CCA772 or CCA774 prefabricated cords (0.6, 2 or 4 meters). MSA141 analog output module. MT11010 MET148-2 temperature sensor module. MET148-2 temperature sensor module Temperature measurement (e.g. in transformer or motor windings) is utilized by the following protection functions: b thermal overload (to take into account the ambient temperature) b temperature monitoring. With the MET148-2 module, 8 temperature sensors may be connected. b type of temperature sensor Pt100, Ni100 or Ni120 according to parameter setting b 3-wire temperature sensors b connection of temperature sensors to screw-type connectors: v 1 wire with cross-section 0.2 to 2.5 mm² (u AWG 24-12) v or 2 wires with cross-section 0.2 to 1 mm² (u AWG 24-16) b a single module for each Sepam series 20 base unit, to be connected to one of the CCA770, CCA772 or CCA774 prefabricated cords (0.6, 2 or 4 meters) b 2 modules for each Sepam series 40 base unit, to be connected to one of the CCA770, CCA772 or CCA774 prefabricated cords (0.6, 2 or 4 meters). 32
