Switch Amplifier, HiC2851

  • 1-channel isolated barrier
  • 24 V DC supply (bus powered)
  • Input for approved dry contacts or SN/S1N sensors
  • Active voltage output
  • Passive transistor output (resistive acc. to EN 60947-5-6)
  • Line fault transparency (LFT)
  • Up to SIL 3 acc. to IEC/EN 61508

This isolated barrier is used for intrinsic safety applications.

The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from a hazardous area to a safe area.

The input controls one 24 V DC active voltage output and one passive transistor output with a resistive output characteristic (acc. to EN 60947-5-6).

The passive transistor output has three defined states: 1-Signal = 1.8 kΩ, 0-Signal = 14 kΩ and fault > 100 kΩ.

Lead breakage (LB) and short circuit (SC) conditions of the control circuit are continuously monitored.

Unlike a SN/S1N series safety sensor, an approved dry contact requires a 10 kΩ resistor to be placed across the contact in addition to a 1.5 kΩ resistor in series.

This device mounts on a HiC termination board.
