Panel-mounted temperature monitor ERW72.4

The temperature controller ERW 72.4 requires the resistance value of a PT100 3-wire sensor as input signal. The desired switching point of the relay can be finely adjusted on the front of the housing.  The relay is potential free and has a switching capacity of 250 V  AC max 600 VA with a maximum switching current of 3 A. Features Adjustable temperature controller for Pt 100 Low-Cost version 22,5 mm Gehäuse for DIN rail Power supply 24 V DC Circuit monitoring for break and short-circuit Applications: Control cabinet installation, Temperature monitoring Technical data: Measuring input - PT100 DIN, 3-wires Output - Potential-free relay - activated when actual value < setpoint value Switching capacity - 250V AC max. 600 VA - 125V DC max. 120 W Accuracy - ≤ ± 2 % FS @ 25 °C Power supply - 18...30V DC, max. 40 mA, max. ripple 10% within permissible range Temperature coefficient - ≤ ± 0,02 % FS/K Housing - Polyamide 6.6
