The PXC-24 provides control of 24 points, including 16 software-configurable universal points.
Point count includes: 3 Universal Input (UI), 9
Universal I/O (U), 4 Super Universal I/O (X), 3 Analog
Output (AOV), 5 Digital Output (DO).
Input/Output Points
* The PXC Compact input/output points perform A/D or D/A conversion, signal processing, point command output, and communication with the controller processor. The terminal blocks are removable for easy termination of field wiring.
* The Universal and Super Universal points leverage TX-I/O™ Technology from Siemens Industry to configure an extensive variety of point
types.
* Universal Input (UI) and Universal Input/Output (U) points are software -selectable to be:
* 0-10V input
* 4-20 mA input
* Digital Input
* Pulse Accumulator inputs
* 1K Ni RTD @ 32°F (Siemens, Johnson Controls, DIN Standard)
* 1K Pt RTD (375 or 385 alpha) 32°F
* 10K NTC Thermistor (Type 2 and Type 3) 77°F
* 100K NTC Thermistor (Type 2) 77°F
* 0-10V Analog Output (Universal Input/Output (U) points only)
* Super Universal (X) points (PXC-24 and PXC-36 only) are software-selectable to be:
* 0-10V input
* 4-20 mA input
* Digital Input
* Pulse Accumulator inputs
* 1K Ni RTD 32°F (Siemens, Johnson Controls, DIN Standard)
* 1K Pt RTD (375 or 385 alpha) 32°F
* 10K NTC Thermistor (Type 2 and Type 3) 77°F
* 100K NTC Thermistor (Type 2) 77°F
* 0-10V Analog Output
* 4-20 mA Analog Output
* Digital Output (using external relay)
* Dedicated Digital Input (DI) points (PXC-16 and PXC-36 only) are dry contact status sensing.
* Digital Output (DO) points are 110/220V 4 Amp
(resistive) Form C relays; LEDs indicate the status of each point.
* All PXC Compact Series models support 0-10 Vdc
Analog Output (AO) circuits.
* On PXC-24 and PXC-36 models, the Super
Universal circuits may be defined as 4-20 mA current AO.
Power Supply
* The 24 volt DC power supply provides regulated power to the input/output points and active sensors. The power supply is internal to the PXC
Compact housing, eliminating the need for external power supply and simplifying installation and troubleshooting.
* The power supply works with the processor to ensure smooth power up and power down sequences for the equipment controlled by the I/O points, even through brownout conditions.
