Built with advanced process control capabilities, the Autonics TX4S-B4S delivers precise PID-based thermal regulation in fast-changing environments. It operates reliably on a wide 100–240VAC power supply and offers a fast sampling cycle of 50ms to ensure responsive adjustments in real time. Its SSR drive output (12VDC) supports ON/OFF, phase, and cycle control modes—making it ideal for use with solid-state relays in precision heating systems. The device offers five control methods—ON/OFF, P, PI, PD, PID—giving engineers flexibility to select control logic suited to their application needs.
The TX4S-B4S supports a wide input sensor range, including thermocouples (K, J, T, R, S, L) and RTDs (DPt100Ω, Cu50Ω), allowing seamless integration with standard industry sensors. The unit features a 4-digit 11-segment LCD display for easy monitoring and parameter configuration. Its display accuracy is within ±0.3% at room temperature, ensuring minimal deviation and high trust in setpoint control. Engineers can adjust proportional band, integral time, derivative time, and hysteresis settings to fine-tune performance. The controller is protected by double insulation (3kV) and features an IP50-rated front panel, enabling safe operation in dusty and electrically noisy environments.
Designed to operate in ambient temperatures ranging from -10°C to 50°C and humidity levels up to 85% RH, the TX4S-B4S performs dependably in India’s diverse industrial climates. The built-in RS485 communication and dual alarm outputs support integration into SCADA and PLC systems. With a compact footprint and a weight of just 146g, this controller fits easily into tight control panels without compromising functionality. Backed by Autonics’ trusted engineering, this model is a preferred choice for automation specialists and control system integrators.
