Deltas Programmable Logic Circuits are with high performance. High speed DVP Series PLCs are the most efficient and cost-effective which incorporates communication capabilities. The advantage of this slimline PLC includes numerous built-in convenient for easy operation access and communication function monitoring. The Analog input module of DVP04AD-Sreceives external 4-point Analog signal input (voltage or current) and converts it into 14 bits digital signal. The Analog input module of DVP04AD-S series can also read/write the data of Analog input module by using instructions FROM/TO via DVP-PLC SS/SA/SX/SC/SV Series MPU program. There are 49 CR (Control Register, each register has 16-bit) in each of its module.
