Product catalog summary
Series Overview:
The document discusses the SG 2431 series of electronic switchgears, highlighting their key features and functionalities. These include a 10-digit diode matrix for actual value indication, LED indicators for operating state, relay output status, current/voltage input, and front-side limit value adjustment. The devices offer easy adjustment via key switches and include functions for level control and additional delay functions of 5 seconds and 0.1 seconds.

Functionality:
The switchgears can process direct current or voltage signals. The input signal is compared with a digitally set limit value, and a relay is activated if the signal exceeds or falls below this limit. Two switching functions are possible due to potential-free change-over contacts. Hysteresis can be adjusted between 1-99% using front-side controls. The relay's status is indicated by an LED, and various options are available for setting switching points and other parameters.

Technical Data:
  • Inputs: Direct current (0(4)-20mA) with resistance of approximately 50Ω or voltage (0(2)-10VDC) with resistance of approximately 100kΩ. Temperature error is less than 30ppm/°C.
  • Supply: AC voltage of 230V (200-250V) at 50-60Hz, 10mA. EMC standards EN 50081-1 and EN 50082-2 are met.
  • Output: Potential-free change-over contacts with a contact load of less than 2000VA and a switching voltage range of 0.1-250VAC, supporting a maximum of 8A resistive load.
  • Response Time and Hysteresis: Details provided in a table (not included in the summary).
  • Contact and Mechanical Lifetime: 105 cycles at 8A and 30 million cycles, respectively.
  • Ambient Conditions: Storage temperature ranges from -40 to +70°C, and operating temperature ranges from 0 to 55°C. Isolation voltage is less than 4kV for input/output and auxiliary AC voltage.
  • Mounting Details: Housing is designed for top hat rail mounting with protection class IP20 for the housing and IP10 for clamps. The width is 22.5mm, and the weight is 160g.

Nach interner Aufbereitung des Eingangssignals wird dieses mit dem digital eingestellten Grenzwert verglichen und bei Über- bzw. Unterschreitung des Mess-Signals ein Relais erregt. Durch die Relais mit jeweils einem potentialfreien Umschaltkontakt lassen sich zwei Schaltfunktionen realisieren. Eine Hysterese kann z.B. von 1-99% durch frontseitige Sollwertvorgabe des „oberen Grenzwertes“ und...
