Dual-Range Inputs for Maximum Flexibility
The AAB841-S00 S2 accepts both voltage and current signals on each input channel. You therefore connect any combination of 1–5 V transmitters and 4–20 mA loop-powered devices. This flexibility simplifies procurement and reduces spare module inventory. The module automatically accommodates either signal type without jumpers or switches.
Superior Accuracy Across Full Scale
Yokogawa specifies input accuracy within ±4 millivolts for voltage measurements. Output accuracy reaches ±48 microamps for current loop control. Consequently, you achieve precise valve positioning and reliable indication. The AAB841-S00 S2 maintains this performance across the entire -20 °C to +70 °C operating range.
Ten-Millisecond Update for Real-Time Control
This module refreshes all sixteen channels every 10 milliseconds. You therefore receive fresh process data ten times per second. The rapid update rate supports fast-acting PID control strategies. Cascade loops and feedforward applications benefit from this minimal latency.
Optimized Response Characteristics
Input step changes settle within 100 milliseconds for stable readouts. Output steps respond in just 40 milliseconds for immediate actuator correction. You can tune control loops aggressively with these fast response times. The AAB841-S00 S2 therefore suits both flow control and temperature regulation.
Temperature Stability Without Compromise
The module exhibits only ±0.1 percent drift per 10 °C temperature change. This stability eliminates seasonal recalibration requirements. You achieve consistent measurement accuracy year-round. The AAB841-S00 S2 performs reliably in non-conditioned shelters and outdoor cabinets.
Power Supply and Consumption Details
You must supply both 5 V and 24 V DC power to this module. The AAB841-S00 S2 consumes 310 mA from the 5 V logic supply. It additionally draws 250 mA from the 24 V loop power source. This dual-supply architecture isolates field circuits from processor electronics.
Mechanical Specifications and Installation
The module weighs precisely 0.3 kilograms with connectors installed. Its 45 mm width occupies minimal DIN rail space in crowded cabinets. Removable terminal blocks permit off-line wiring harness assembly. You therefore reduce panel installation time significantly.
