SAIA-Burgess Controls PCD2.W200 Analog Input Module

The SAIA-Burgess Controls PCD2.W200 is an 8-channel analog input module for SAIA-Burgess PCD2 controllers that accepts 0 to 10 V signals with 10-bit resolution. It performs non-differential, single-ended measurement with an input impedance of 200 kΩ and an accuracy of ±3 LSB (repeatable within 1 LSB), delivering an A/D conversion time of ≤50 μs and an input filter time constant of about 5 ms. There is no galvanic isolation between inputs and the bus, while protection includes ±50 VDC overvoltage and IEC 1000-4-4 burst protection of ±1 kV unshielded (±2 kV shielded). Power is drawn from the host system: 8 mA from the +5 V rail and 5 mA from the V+ rail, with no external supply current, and the module uses a plug-in 10-pole screw terminal block for wires up to 1.5 mm². Weight is about 35 g, and the terminals use plug type L (4 405 4847 0); this module is typically used to read sensor voltages in process control or building automation, feeding 0–10 V signals into the PLC for monitoring and control.
