Physical Characteristics and Installation
This analog module weighs approximately 0.54 kg for standard rack mounting. Its dimensions measure 250 mm x 25 mm x 210 mm for S5 single-width slots. First, slide the 6ES5243-1AA12 into a free I/O rack position. Then, connect your sensors and actuators to the screw terminals. Finally, secure the module using the top and bottom locking screws. LED indicators on the front confirm power and operational status.
Input Specifications and Signal Conversion
The 6ES5243-1AA12 provides 4 analog input channels for field sensors. Each input accepts voltage ranges of 0 to 10V or ±10V. For current loops, select 0 to 20 mA or 4 to 20 mA. A 12-bit resolution delivers precise digital values for process variables. The conversion time requires 10 ms per channel for accurate readings.
Output Specifications and Power Requirements
This analog module delivers 2 analog output channels for actuator control. Each output supports 0 to 10V, ±10V, 0 to 20 mA, or 4 to 20 mA. The 12-bit output resolution ensures smooth analog regulation. The settling time takes only 5 ms for responsive adjustments. The 6ES5243-1AA12 requires both 5V DC logic power and 24V DC field power. Use this module for compact mixed analog applications.
