1. 0-2 V Analog Output Signal Option
The analog output signal is available on pins B and C of the circular 6 pin
connector located on the rear of the unit. The signal is short circuit protected and
capable of driving low impedance external loads with fixed gain to a specified
output level, with 10K Ohm and above loads. Frequency response is a function
of the pressure range, generally 1 to 3 KHZ. Loading of the analog output will
result in a reduction of the battery life expectancy due to the additional current
through the external load.
2. Alarm(s) Option
The two open drain alarm output signals are present on pin D (alarm 2) and
pin E (alarm 1) of the output connector. The alarm trip-points are software
selected by using the unit’s front key-pad (see section 3.0 in the instructions
section of this manual). When active, they are capable of sinking 500 mA at 60
VDC Max with 7.5 ohms typical ON resistance to the digital ground as if they
were two independent SPST normally closed switches with one end connected
to the digital ground and the other end presented as an output. The typical
configuration will require an external power supply and a 1 to 10K Ohm pull up
resistor connected between the positive terminal of the power source and each
alarm output. Inductive load switching such as small solenoids or relays is also
possible utilizing the alarm output as a “low side switch”. The use of a diode or
a capacitor across the load terminals is required to reduce “kick-backs”.
