Maximum load resistance on outputs: 600 ohms
2.12 Fault indicator outputs
Two fault-indicating relay outputs are provided:
1. Instrument status
2. Reactor status ±10°C of set point.
Both are volt-free SPDT relay contacts rated at 30V AC or DC, 0.5A. The “no-fault” condition
is NC - see Figure 6.
2.13 Concentration alarms
Two user-configurable Alarm outputs are provided:
1. Programmable alarm for Cl
2
2. Programmable alarm for H
2
Both are volt-free SPDT relay contacts rated at 30V AC or DC, 0.5A. The “no-alarm”
condition is NC - see Figure 6.
