Large Display Alarm LED’s The 12.5mm LCD display is easy to read, even from a distance. Switch to Set Upper Limit or Set Lower Limit to display and set the control limits. Separate Alarm LED’s for the High and Low Set Points provide visual indication of when the control limits are exceeded. Automatic Control Analogue Outputs Relay Outputs 4 to 20 mA and 0 to 1 V outputs can be userselected and are supplied as standard. A custom 4 to 20 mA output can be factory set, in addition to the usual 4 to 20 mA output for 0 to full scale. The relay outputs are rated to 2 amps at 240 V AC. The limits...
