EMEC - Digital Controller - LD Series Controller, Single Function Control

LD MULTICHANNEL

CONTROL INSTRUMENT

LD MULTICHANNEL control instruments are a series of multiple reading digital systems that meet a wide range of applications.
They are multiple digital measuring systems for complete control of water treatment and chemicals dosage, ensuring, depending on model, the control on acid (pH) and on a second parameter (by customer request different parameters combination can be set).

LD MULTICHANNEL instruments have: easy control by encoder wheel, flow control, local & remote control, ERMES web communication, permanent data storage with system log, PT100 temperature probe, stand-by input, alarms, programmable delay at dosing start-up (up to 60 minutes), priority dosage, probe readout menu and check-up, multiple probe readings can be viewed, working modes (on/off, impulsive proportional, proportional PWM and fixed PWM), automatic or manual dosing activity, chlorine/bromine selection with ECL6 (LDPHCL), flocculant output 230 VAC (LDPHCL and LDPHRH) and mA output (optional).
