AutomationDirect P3-32ND3 Discrete Input Module

The AutomationDirect P3-32ND3 is a 32-point discrete input module for Productivity3000 PLCs that accepts 24 VDC sensors and switches and supports both sinking and sourcing wiring. Each module provides four isolated common terminals (eight inputs per common) and uses a 40-pin IDC input connector; backplane connection is via ZIPLink modules and pre-wired ZIPLink cables. The module's DC inputs are rated for 24 VDC operation (±10%), with typical input current around 5 mA per input and a maximum of 6 mA at 60°C; input impedance is 4.7 kΩ, with ON defined as greater than 18 V and OFF as less than 8 V. Response times are fast, with OFF-to-ON and ON-to-OFF transitions specified at 2 ms maximum (typical 1 ms). No terminal block is included on the module itself; ZIPLink connector modules and pre-wired cables are required to connect to the Productivity3000 backplane. The P3-32ND3 is designed specifically for Productivity3000 systems and is ideal for expanding digital input capability in automation projects that monitor multiple switches, sensors, and other 24 VDC devices.
