The Multispan UTC-421G-RG-A2-00 Temperature Controller belongs to the TC Series listed on IndMALL and supports temperature regulation in industrial automation. Its auto-tune PID and ON-OFF control modes provide selectable control methods, while configurable inputs accept J/K thermocouples or a 3-wire PT-100 RTD. The J input covers 0–600°C, K covers 0–1200°C and PT-100 covers -50–400°C. A four-digit dual red/green display presents the process value above the setpoint value. Parallel relay and SSR drive outputs provide connections for compatible temperature-control circuits.
In plastic processing, conveyor-based packaging and automated assembly, this controller can regulate stages that require temperature control rather than conveyor movement or object detection. The separate process-value and setpoint displays help operators compare measured temperature with the required setting. For installation details, consult the Utc 421g rg a2 00 manual; use the Utc 421g rg a2 00 datasheet to check sensor compatibility, output ratings and panel dimensions. A Utc 421g rg a2 00 price enquiry should identify the exact variant to keep the quotation aligned with the required configuration.
The Multispan UTC-421G-RG-A2-00 Temperature Controller combines configurable temperature inputs with a 5A relay and 12V DC, 20mA SSR drive. Its 100–270V AC, 50/60 Hz supply supports the specified power connection, while the 48 × 48 × 95 mm housing requires a 45 × 45 mm panel cutout. IP65 front panel protection applies to the front surface. Suitability for an industrial installation depends on matching the sensor range, control mode and connected load to these specifications, with manufacturer documentation providing the basis for wiring and configuration.
