1. 24 VDC maximum on internal card surfaces Installation Services The OP driver measures ORP and pH sensors The Controller powers the OP card using its internal 12VDC supply and measures pH on the C input and ORP on the D input The DCM5 only allows the pH ORP configuration although other configurations of the OP driver are possible Up to two dual sensor OP drivers may be installed in a DCM5 controller The second OP driver would be installed in the E and F slot Pool 2 pH is then assigned to E and Pool 2 ORP to F Faster Response Lower Temperature The OP responds immediately to pH changes The extremely high sensor input impedance of the OP supports water pH measurement below 40 F 5 C Fie Solution Ground Required The faster response and improved low temperature performance makes the pH sensor more sensitive to electrical noise and requires a solution ground for both operation and calibration Do not calibrate the pH sensor on line or in a buffer solution unless the solution ground is connected and immersed in the same sample as the pH sensor CETRA Static Discharge The faster response and improved low temperature performance also makes the OP_Ext driver sensitive to static discharge at the sensor connection terminals If you accidentally touch or contact the sensor terminals with the OP Ext power ON static discharge may lock up the sensor input You ll experience the lock up up as a pH mea
