The HD2601V.1 is a 4...20mA passive transmitter display with DIN43650 connector; the HD2601V.2 model is fitted with two independent dual-output transmitter viewers. The display is inserted between transmitter and connector. Power is supplied by the 4...20mA current loop. The snap-in display can be programmed by the user. Two keys can be used to set scale factors, decimal point position, display update time, maximum, minimum and average values display, time passed after turn-on, open-collector digital output parameters of the single display version. The programmable parameters are saved into a permanent memory and are not erased when power is disconnected. All device functions are continuously monitored by an integral diagnostic system. In the single model HD2601V.1, the open-collector digital output can control a digital device or a relay coil. The instrument display can be rotated at 90° or overturned to fit different installation conditions. Technical characteristics Display 4 digit LED, 7.6mm high. The decimal point position can be programmed.
