DPJ-IO: Connect strain gauge sensors directly to IO-Link
Scaime's DPJ-IO amplifier connects load cells and other strain gauge sensors directly to IO-Link systems in automated process plants – with digital transmission of measured values, parameters and diagnostic data.
Scaime introduces the DPJ-IO, a signal conditioner that connects strain gauge sensors to IO-Link automation systems. The DPJ-IO is designed primarily for automated process plants, for example for weighing tanks and silos, for dosing and filling processes, or for force measurement on machines.
Digital instead of analogue
Instead of analogue transmission via 0–10 V or 4–20 mA, which is prone to signal loss and electromagnetic interference, the DPJ-IO uses fully digital point-to-point communication based on IO-Link 1.1 (COM3, up to 230.4 kBaud). Measured values, parameters and diagnostic information are available directly in the PLC or control system.
Fast and precise measurement
The DPJ-IO accepts 4-wire or 6-wire strain gauge sensors – up to four sensors in parallel with a minimum impedance of 80 Ω, such as the load cells of a tank. A 24-bit converter with a sampling rate of up to 4,800 Hz and a cycle time from 1 ms ensure fast and precise measurement. Various filters (Bessel, Butterworth, exponential moving average) adapt the signal to the respective process.
Easy commissioning and maintenance
Configuration is centralised via IO-Link. This shortens commissioning, simplifies device replacement and makes maintenance easier. The diagnostic data help to detect faults early, reduce downtime and increase plant availability.
Rugged for industrial use
The anodised aluminium housing is rated IP67 and designed for mounting directly on the plant. The DPJ-IO is suitable for weighing, force, torque and pressure measurement and is aimed at plant builders, system integrators and operators who want to integrate their measurement technology into Industry 4.0 architectures. The DPJ-IO is designed and manufactured in France.
