The Sepam MES114/120 I/O module does not have an input that can monitor the value of an analog signal generated from an external power source. The Sepam I/O modules are designed to detect status changes of a circuit breaker, contactor, plc, etc....., and will output a "0" or "1", depending on the condition of the input signal. The MES114 I/O module (compatible w/ Series 20/40) has up to 10 input connections and the MES120 (compatible w/ Series 80) has up to 14 input connections.
The Accessory MES114 and MES 120 can be used only in Logical Status
The MES114 module, on the other hand, will accept analog input signals, but the input APS_SENSORS will only detect whether the status of the analog signal is high "1" or low "0" depending on a certain threshold. These thresholds can be located in the characteristics section of the MES114 install sheet:
For a 110 V AC analog signal, a signal greater than 88V will force a "1" state and a signal less than 22V will force a "0" state.
For a 220 V AC analog signal, a signal greater than 176V will force a "1" state and a signal less than 48V will force a "0" state.
These input status changes can then be used by the Sepam relay to influence control logic, display alarm messages & LEDs, trigger waveforms or open & close relay outputs.
Nevertheless sepam can use the Accessory MSA 141 to manage an Analogic Output
