Alarms
Two (optionally four) individual setpoints control an own signal output (2 as SPDT relays
contacts, 2 as option with PhotoMOS relay contacts). Each with individually programmable
response characteristics, and each with programmable starter.
2.14
Analog Output (D521.10, D521.12, D521.14)
Output signal isolated and linear as current 0/4… 20 mamps into 750 Ohms max load, or volt-
age 0/2 volts …10 volts under max. 10 mamps load.
Live zero as well as high and low end of conversion programmable.
2.15
Signal Pulse Output 1
Repeating the input pulse signals (undivided) by the same sequence, as square wave pulses of
approx. 10 volts and 1 kOhm source impedance. Same reference as input.
2.16
Signal Pulse Output 2
Isolated (passive) output by optocoupler, for max load 30 volt / 10 mamps. Pulse sequence as
reduced by the input pulse divider. Max output frequency 12 kHz (at a 1:1 duty input signal).
Output must be powered externally.
