Product Overview

The IM1-22EX-T is a 2-channel Isolating Switching Amplifier equipped with intrinsically safe input circuits. The sensors according to EN 60947-5-6 or potential-free contact transmitters can be connected to the device. The output circuits feature 2 potential-free and short-circuit proof transistors. Six front panel switches are available to set the output mode separately for each channel (NO/NC mode), as well as to enable/disable wire-break (WB) and short-circuit (SC) monitoring separately. When using mechanical contacts, wire-break and short-circuit monitoring must be switched OFF or the contacts must be wired to resistors. The PWR LED lights green to indicate operational readiness. The 2-color LEDs 1 and 2 light yellow to indicate the switching status of the associated output. In the event of an input circuit error, the LED associated to the affected input turns red, provided the input circuit monitoring function is activated. Thereupon the associated output transistor is blocked.
  • Output mode adjustable (NO/NC mode)
  • Complete galvanic isolation
  • Universal voltage supply unit
  • ON/OFF switchable circuit monitoring
  • Green operational readiness
  • Yellow switching state
  • Red error indication
  • IP20 Protection rating
