 The DRSL-RTD Series RTD input DIN rail signal conditioners provide a competitive choice in terms of both price and technology for interfacing RTD inputs to SCADA systems or PLC equipment. The DRSL-RTD and DRSL-RTD-ISO can be used for signal conversion of 2, 3 or 4-wire Pt100 RTD inputs into unipolar analog signals. The DRSL-RTD-ISO isolated model offers 3-way isolation between input, output and supply and provides surge suppression and protects control systems from transients and noise. Low power consumption facilitates DIN rail mounting without the need for any air gap. Easy configuration of more than 1000 factory calibrated measurement ranges is done via DIP-switches. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).

• DRSL-RTD Non-Isolated and DRSL-RTD-ISO Isolated Models
• 2, 3 or 4-Wire Pt100 RTD Input
• Pre-Calibrated Temperature Ranges Selectable via Dip-Switches
• Slimline Housing—Only 6 mm (0.24') Wide
