General Specifications
Loop Driver Output Capability 600mA average, 1,2A peak
Auxiliary 24V Output Current
150mA maximum ( limited by monitored, self resetting thermal 'fuse' ). Any
overload must be completely removed to clear a fault condition
Auxiliary 24V Fault Thresholds
An ‘Aux Supply Fault’ is generated when the voltage on the
Aux. 24V output drops to 75% of the panel running voltage
Control Input 1 and 2 Trigger Levels 50Ω or less for 1 second to activate. Open circuit to de-activate
Global Fault Relay Output Volt free changeover contacts rated at a maximum of 1A at 24V dc
