Cerlic BB2 Central Unit is now available in a 24 VDC version.
To keep up with changing worldwide plant standards, a 24 VDC version of the BB2 Central Unit has been released.
Still capable of managing up to four separate sensors with any combination of the X-series sensor range of suspended solids, (ITX, CTX-LC and ITX-IL), dissolved oxygen (O2X DUO), pH (pHX) and redox (ReX). The low-voltage DC unit is reverse-compatible with existing Cerlic equipment and can directly replace a line-voltage unit as part of an upgrade, with no further hardware required.
The BB2 provides up to four 4 – 20 mA analog output channels with the option of Proibus DP for digital control circuits. Like with the line-voltage (240 VAC) model, there are still two independent (dry contact) relays in the BB2 which can be programmed for high/low alarms or to trigger the selfcleaning of sensors (pressured air or water).
