High-Precision Analog Signal Acquisition
The 45C340 analog PLC input module delivers eight high-precision analog input channels for accurate process measurement and monitoring. This analog PLC input module accepts field-configurable signal types, allowing each channel to operate independently as 4-20 mA, 0-20 mA, or 0-10 VDC. The 14-bit resolution ensures exceptional measurement granularity for demanding process control applications.
The module achieves an outstanding accuracy of ±0.05% of full scale at 25°C, making it suitable for precise temperature, pressure, and flow measurements. The temperature drift of only ±25 ppm/°C maintains this accuracy across a wide range of ambient conditions. A fast 1 ms conversion time per channel enables real-time monitoring in high-speed applications.
Superior Noise Rejection and Isolation
This analog PLC input module provides 1500 VAC isolation between individual input channels, eliminating ground loop issues and improving signal integrity. The module’s 80 dB common mode rejection and 60 dB normal mode rejection effectively attenuate electrical noise from motors, drives, and other industrial equipment. These specifications guarantee stable readings even in electrically noisy environments.
The 45C340 includes input over-voltage protection up to ±30 VDC, preventing damage from accidental wiring faults. The module accepts current loops with impedances as low as 250 Ω or voltage inputs with impedances above 1 MΩ, accommodating a wide range of field instruments.
Physical Design and Installation Features
This analog PLC input module occupies a single slot in the Automate 13-slot rack and measures 60 mm in width. The module weighs 0.32 kg, making handling straightforward during installation and replacement. A 34-point removable screw terminal block on the front panel accepts all field wiring connections, simplifying both initial installation and ongoing maintenance.
Eight green LEDs provide clear visual status indication, with one LED per channel showing active signal presence. This comprehensive indicator set enables rapid troubleshooting without requiring a programming terminal. The terminal block accepts wires up to 2.5 mm² (AWG 14), ensuring secure and reliable connections.
Power and Environmental Specifications
The 45C340 draws 300 mA from the 5 VDC backplane, ensuring stable operation in fully populated racks. This analog PLC input module operates reliably across a temperature range of 0°C to +55°C. It also withstands humidity from 10% to 90% (non-condensing) and resists vibration up to 2G at 10-100 Hz, making it suitable for diverse industrial environments.
