The LCU032 Series Temperature/Process Indicators set a new standard in power, flexibility, and value in a low cost 1/32 DIN control. While the LCU032 is primarily a control, it is equally useful as an indicator. The same flexibility of inputs combined with the large single display, makes the LCU032 an excellent choice for most any application requiring indication. As an additional bonus, the output usually used for the set point can be programmed as a 4 to 20 mA retransmission output. Where else can you get an indicator with a large display, universal input, retransmission, and alarm for a price that competes with many single use, display only indicators?
The LCU032 offers universal input (13 thermocouple scales, 2 RTD types, voltage, and current).
Optional for the LCU032 is RS-485 Modbus Serial Communication.
