The programmable PMS-970T indicator is applicable to cooperation with the transmitters having a standard current or voltage output signal. Measurement is visible on 4-digit indication and 26-point bargraph. Four alarm values controlling the relay outputs can be programmed. Alarm values are indicated on bargraph and exceeding of the alarm values is indicated by diodes on the front of the display.
The device can use a linear characteristic or a multisegment characteristic freely definable by the user. The meter has RS-485/MODBUS RTU digital output and can also be provided with an a passive current output with programmable range of current variation.
The PMS-970T enables the following parameters to be programmed:
Measuring value display range and decimal point position
Level and hysteresis of action of relays
Relay operation mode: normally connected or normally disconnected
Input signal conversion characteristic (segmental approximation, max. 15 segments)
Display filtering level
Alternating control of outputs” function used to balance wear on groups of pumps
Two modes of bargraph: 2 and 3 color
Features
Universal measuring input 4...20 mA, 0...20 mA or 0...10 V
