1 - ENGLISH Thank you for choosing Delta'

s DVP series PLC. Delta releases DVP02LC-SL load cell module of weight measurement function. DVP02LC-SL provides 24-bit resolution applicable for 4-wire or 6-wire load cells with various eigenvalues. Therefore, the response time can be adjusted in coordination with each other according to users'

needs. On this basis, the market requirements on weight measurement can easily be met. a This instruction sheet provides introductory information on electrical specifications, general specifications, installation and wiring. a This is an OPEN TYPE I/O module and therefore should be installed in an enclosure free of airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required to open the enclosure) in case danger and damage on the device may occur. a DO NOT connect the input AC power supply to any of the I/O terminals;

otherwise serious damage may occur. Check all the wiring again before switching on the power. Make sure the ground terminal is correctly grounded in order to prevent electromagnetic interference. a The tightening torque for I/O terminal block is 1.95 kg-cm (1.7 in-lbs). Use 60/75°C copper conductors only. ? Product Profile &
