Figure 3 Sensor Input PCA

Four "quick connects" on the side of the CXT are for sensor connection (Figure 4), supply power to the

sensor from the internal battery and accept the 4-20mA signal from the sensor.

NOTE

Power supplied to the sensors is 11VDC. Any attached sensor must be designed to work at

this voltage level.

The four sensor input lines are fused at the PC board level for safety purposes. These fuses are not

designed for field replacement and shall not under any circumstances be attempted to be changed out by

anyone but Detcon Factory trained Service personnel.

CAUTION

These PC board mounted fuses are not designed for field replacement and shall not

under any circumstances be attempted to be changed out by anyone but Detcon
