2 types of CPU are available according to programminglanguage.SA: Stage typeSR: Relay symbol type- Module addition: Up to 8 slot- Maximum I/O points: 168 points- Program memory: 512 to 3.7 K- Data memory: 192
All the I/O modules have action indication with 8-point and 16-point modulesavailable.
Up to 168 I/O Points Can be Equipped.
The D3 series is a free location type that allows free selection of the balanceand type of input/output and up to 168 points.
D3-05B-1: Up to 112 points
D3-08B-1: Up to 152 points
D3-10B-1: Up to 168 points
Large Memory Capacity
The SA-21-EX can cover 512 words in the basic configuration and 1,535words when expanded, and the D3-330P can cover 3,701 words and have128 stages. They can cover small-scale to medium-scale control.
Data processing instructions are equipped.
Read and write instruction: 16 bit, 8 bit, 4 bit
16-bit operation instruction: Four rules of arithmetic, logic operation,comparison, inversion, code conversion, shift
The Pause Function for Stopping the Machine on theSpot and Resuming Operation
The D3 series has a pause relay (No.176) that has the functions of prohibitingonly external output while retaining the operating state of the circuit duringoperation. If the conditions for making the relay ON are programmed, youcan stop the machine on the spot and resume operation according to theconditions.
Operating State Monitor
Operation can be easily checked by a "16-point block monitor" or the "ON/OFF check monitor".
High Speed Instruction Execution Processing
Processing speed: Average 10 ms (0.5 K word)
