Universal Inputs :Linkable for analogue voltage (V),
analogue current (I), thermistor (T) or
digital (D).
Analogue voltage (V) :12 bit resolution (4096 steps -
effective). Minimum 60 dB series mode
rejection at supply frequency. 0 to 10V,
input resistance 200 kΩ, accuracy 50
mV equivalent to ±0.5% of span.
Analogue current (I) :12 bit resolution (4096 steps - effective).
Minimum 60 dB series mode rejection
at supply frequency. 0 to 20 mA, input
resistance 240 Ω 0.1%, accuracy 0.5%
of span (i.e. 100 µA). Loop powered
input supply is 20 to 36 Vdc self-limiting
at 22 mA.
Thermistor (T) :12 bit resolution (4096 steps - effective).
Minimum 60 dB series mode rejection
at supply frequency. Thermistor bridge
resistor 10 kΩ 0.1%, accuracy 0.5% of
span. Bridge supply 5V.
Digital (D)
:Volt free contact. Count rate 30 Hz. Wetting
current = 4 mA nominal @ 24 Vdc. 24 V
supply pin is self-limiting at 22 mA.
Status LED per channel (ON = closed
contact).
Outputs
Analogue voltage :8 bit resolution (256 steps). 0 to 10
V with 20 mA current limit, accuracy
±100 mV equivalent to ±1% of span.
Status LED per channel, light intensity
increases with output voltage.
