*
TX-I/O modules support only 0 ... 20 mA. For a range of 0 ... 25 mA, use the shunt for 400 Ohm (0.1%, 1 W) and measure the
voltage with U10.
I/O configuration PX Compact
The analog input block is used in the Desigo PX Compact PXC10 TL to PXC52 automation station in cases
where an LG Ni1000 sensor (signal type R1K) or DC 0…10 V (U10) is connected to device terminals
X1…X16 of Module 001.
The following information results:
Signal type measurement Description Standard measuring range [Slpe] [Icpt]
R1K LG-Ni 1000 -50…150 °C 0.01 0
U10 DC 0…10V 0…10 Volt 0.001 0
BACnet referencing
Reference to a value in another BACnet object. As the referenced value is already available as a converted
or resulting value, no conversion is required, that is, [Slpe] must be defined as 1 and [Icpt] as 0.
PPS2 interface
The measured value from a room unit connected via the PPS2 interface. In the analog input block, only
Objects 24 (setpoint correction) and 40 (room temperature) may be used. As the value is already available
as a converted or referenced value, no conversion is required, that is, [Slpe] must be defined as 1 and
[Icpt] as 0.
[Slpe] and [Icpt] Analog Output
I/O modules PX modular
In the PX modular automation stations, the analog output block is used with the following signal types:
Signal type positioning Description Standard measuring range [Slpe] [Icpt]
Y10S DC 0…10 V 0 … 10 V 100 0
Y420 DC 4…20 mA 4 … 20 mA 160 4000
Y250T (P-bus)* Three-point AC 24…250 Volt 2.55* 0
Y250T (Island bus)* Three-point AC 24…250 Volt 100* 0
Key
*
Value [Slpe] for Y250T is not a physical value, but rather a special code controlling output of the AO to two relay outputs. This
code differs between P-bus and island bus.
I/O configuration PX Compact
The analog output block is used in the PX compact automation stations, when valves or actuators with DC
0…10 V control signals, signal type Y10S, are connected to device terminals Y1…Y8 of Module 004.
