SPECIFICATIONS
Electrical
Power supply 24 VDC, polarity protected
Power consumption 24 VDC, 60 mA (1.5 VA)
- toxic gases & oxygen 1 mA (0.1 VA), max. per sensor
- infrared (CO
2
) 15 mA (0.4 VA), max. per sensor
- combustible gases 55 mA (1.4 VA), max. per sensor
- horn & multi-status LED 40 mA (1.0 VA), max. per sensor
Signal relays Three (3), 250 VAC, 5 A,
potential-free, contacts (SPDT);
2 programmable & 1 fault;
programmability is determined by
the number of connected sensors
Transistor output Two (2), 24 VDC / 0.1 A
(switching to plus)
Digital inputs Two (2), potential-free
Analog inputs Two (2), 4-20 mA overload
and short-circuit proof,
input resistance 200 Ω
Analog output signal One (1), proportional,
overload and short-circuit proof,
load ≤ 500 Ω
4-20 mA = measuring range;
3.0 < 4 mA = under range;
> 20-21.2 mA = over range;
2.0 mA = fault
Output for local bus 5 VDC, 250 mA max.
Overload, short-circuit and
polarity protected
