Siemens SIPART DR21 PID Temperature Controller, 72 x 144mm, 115 → 230 V ac Supply Voltage

Use this PID temperature controller from Siemens to closely control your industrial system's climate. It uses programmable logic to align your system's temperature with your set value. For versatility, it has both digital and analogue inputs and outputs. You can choose between a supply voltage of 115 or 230V AC for compatibility with a wide range of electrical systems. A quick CPU data cycle time of 100ms means the controller quickly reacts to your inputs for real-time climate management. Temperature controllers like this one are commonly used to manage industrial furnaces and heat treatment processes.

• Silver alloy contacts are highly conductive and corrosion-resistant, so achieve reliable electrical connections
• Large front-mounted LED display makes data easy to read
• IP64 rating on front panel means it's dust-tight and protected against water splashes
• Wide operating temperature range of 0°C to +50°C for use in demanding environments

This unit has a long electrical service life of two million cycles, so you can rely on it for long-lasting temperature control.
