Dual pulse input
1
[1]
High impedance High speed USM counter input, pulse counting.
Trigger level 0.5 V. Max. level 30 V. Frequency range
0 ... 5 kHz (4 x dual pulse) or 0 ... 10 kHz (4 x single
pulse).
Compliant with ISO6551, IP252 and API 5.5.
True Level A implementation.
Digital input
16
[1]
High impedance Digital status input, or test inputs. Update cycle
0.5 ms for 2 inputs, for others 250 ms max.
