Hardware Saia-Burgess Controls AG General Information 1 Hardware 1.1 General Information PCD2/3.W525 is an analogue multipurpose module with four inputs and two outputs. Each input and each output can be individually configured as one of the standard industrial interface type like 0 … 10 V, 0 … 20 mA and 4 … 20 mA. In addition, the inputs can be configured to support Pt/Ni1000 or Pt500 temperature sensors. Furthermore, the module offers high flexibility in selecting filter types and scaling ranges.
Hardware Saia-Burgess Controls AG Configuration 1.2 Configuration 1.2.1 Module connections/LED The connections of the module terminal are the following: 1 Description of the LED: ● Off: Module is not powered. Uext (24 V) is missing. ● On: Module is running without errors ● Blinking slow: Channel error (Over range/under range/short circuit/open load) ● Blinking fast: Uext is lower than specified (< 19 V) 1.2.
Saia-Burgess Controls AG Hardware Function 1.3 Function 1.3.1 Power Supply PCD2.W525 / PCD3.W525 has to be supplied externally! This power supply is galvanically isolated to both, the PCD and the I/Os of W525. Furthermore, the design allows using the same power supply for the PCD and for W525 without loosing the galvanic isolation. These schematics show the different zones of isolation: 1.3.
Saia-Burgess Controls AG Hardware Function 1.3.3 Filter ● Inputs There are two factors, which have filtering effects to the acquired values: ○ The base hardware filter with a time constant of 2ms. This filter attenuates the input signal by 6 dB/decade at a cut-off frequency of 80 Hz. ○ The second influence is caused by software and results in a delay of the acquired value for 2 ms with a notch filter characteristics at 500 Hz if no software based 50 Hz / 60 Hz filter is selected.

Saia-Burgess Controls AG 2 Configuration Meaning of the I/O terminology of a PCD2/3.W525 module When configuring a W525 module using the Device Configurator or the Profi-S-I/O (or Profibus DP) Network Configurator, the PCD2/3.W525 needs two registers for the analogue outputs and 8 registers for the analogue inputs. 2 The meaning of the registers is as follows: Output registers Register Bits 31:16 Bits 15..
Saia-Burgess Controls AG Configuration Value CH0…CH3 (Register n…n+3) This register (bits 0 to 15) contains the analogue input value of the corresponding analogue input. It is a 14 bit value. Load_Current / Load_Voltage (Register n+4) The actual current or voltage value is displayed on this register (bits 0 to 15).
Saia-Burgess Controls AG Configuration Input status table: Bit Description 3 Ouput transistor overheated 2 Not calibrated 1 Over range 0 Under range 2 Output status (Register n+7) This register (bits 0 to 15) contains the status of the two output channels CH0 and CH1. The status of each output channel is displayed in 6 bits. Output status: Bit Description Bits 0..5 CH0 status (LOW BYTE) Bits 8..
