Electrical data
Supply (terminals 51, 52): U = 19.2 ... 31.2 Vdc
Digital outputs (terminals 41, 42 and 43, 44):
Transistor output, Umax = 30 Vdc, Imax = 80 mA (Type ACT20X-HDI-SDO-…-S and Type ACT20X-HDI-
SDO-…-P)
Relay contacts, Umax = 30 Vdc or 32 Vac, Imax = 2 A (Types ACT20X-.HDI-.SDO-…-S and Types
ACT20X-.HDI-.SDO-…-P)
If the Pulse Isolator is installed outside the hazardous area, the following data for the relay contacts apply:
U ≤ 30 Vdc or 250 Vac, I ≤ 2 Adc or Aac respectively.
Status output (terminals 53, 54):
Relay contacts, U ≤ 32 Vdc or 32 Vac, I ≤ 1 Adc or I ≤ 0.5 Aac respectively.
If the Pulse Isolator is installed outside the hazardous area, the following data for the relay contacts apply: U
≤ 110 Vdc or 125 Vac, I ≤ 0.3 Adc or I ≤ 0.5 Aac respectively.
For all circuits above: U

The intrinsically safe sensor circuits are infallibly galvanically isolated from each other and from the non-
intrinsically safe circuits.
