WP-LCD-C Touch Color Paperless Recorder

Short Description:

WP-LCD-C is a 32-channel touch color paperless recorder adopts a new large-scale integrated circuit, and is especially designed to be protective and undisturbed for input, output, power, and signal. Multiple input channels can be chose (configurable input selection: standard voltage, standard current, thermocouple, thermal resistance, millivolt, etc.). It supports 12-channel relay alarm output or 12 transmitting output, RS232 / 485 communication interface, Ethernet interface, micro-printer interface, USB interface and SD card socket. What’s more, it provides sensor power distribution, uses plug-in connecting terminals with 5.08 spacing to facilitate electrical connection, and is powerful in display, making real-time graphic trend, historical trend memory and bar graphs available. Thus, this product can be regarded as cost-effective due to its user-friendly design, perfect performance, reliable hardware quality and exquisite manufacturing process.
