Input Characteristics and Signal Flexibility
The ADV141 module accepts AC signals within a rated voltage range of 100 to 120 V AC at 50 or 60 Hz . It employs opto-isolation on each channel, effectively protecting the control system from electrical noise and voltage transients . The module supports two functional modes: status input for standard ON/OFF detection and pushbutton input for edge counting applications . The status input response time is 160 ms, while the pushbutton input requires a minimum ON time of 200 ms and supports a maximum cycle rate of 2.5 Hz .
Physical Characteristics and Installation
The ADV141 weighs 0.3 kg and features a compact form factor measuring 3.2 x 10.7 x 13.0 cm . This module mounts into standard Yokogawa I/O racks and uses pressure clamp terminals or a dedicated AKB332 cable for field wiring . Its -20°C to +70°C operating temperature range ensures reliable performance across diverse industrial environments . Furthermore, the LED indicators on the front panel display real-time channel status, simplifying diagnostics and maintenance .
Application Scenarios
This module is widely deployed in applications where AC control power is standard and relay elimination is desired . Typical use cases include power plant utility monitoring, large motor control systems, building automation, and safety permissives . However, for 220–240 V AC applications, users should select the ADV142 module instead . The ADV141 is commonly found in oil and gas refineries, chemical plants, and power generation facilities where reliable AC signal acquisition is essential.
