Item #UM33A-020-11, UM33A Controller - Yokogawa

The Yokogawa UM33A digital indicator with alarms is a 1/8 DIN indicator designed to monitor and display processes such as temperature, pressure, flow rate, and other types of data while providing an alarm when an input signal reaches a preset value.

The Yokogawa UM33A digital indicator has eight alarm outputs and eight-screen display points, twice the number of comparable models. A dedicated program eases the task of entering alarm values and other information, eliminating the need to input them using the keys on the front panel of each device. Measurements are shown on the large, easy to ready, 14 segment color LCD. The UM33A includes a scrolling text feature for parameters, user-friendly navigation, programmable function keys, user-settable default values, and RS-485 (Modbus/RTU, peer to peer, coordinated, PC-Link) communications.
