Pin Out of the DB25 female “Output” connector:
For 4-20 ma output of Conductivity (Analog 1), use pins 2 (4-20 -) and 14 (4-20 +). If excitation is needed in the
loop, connect pin 1 (Vpwr) to pin 14 (4-20 +), and connect the output (signal) cable to pin 2 (4-20 -) and pin 15
(Gnd).
For 4-20 ma output of Temperature (Analog 2), use pins 4 (4-20 -) and 16 (4-20 +). If excitation is needed in
the loop, connect pin 3 (Vpwr) to pin 16 (4-20 +), and connect the output (signal) cable to pin 4 (4-20 -) and pin
17 (Gnd).
Analog outputs 3 and 4 are not utilized in the SciCon II.
TTL Outputs:
Hi Conductivity Alarm: TTL 1
Pins 11 (Out0) and 13 (Gnd)
Lo Conductivity Alarm: TTL 2
Pins 24 (Out1) and 13 (Gnd)
Hi Temperature Alarm: TTL 3
Pins 12 (Out2) and 13 (Gnd)
Lo Temperature Alarm: TTL 4
Pins 25 (Out3) and 13 (Gnd)
TTL outputs are either 0 or 5 VDC and carry minimal current. They are for TTL inputs on a PLC, or control of a
5 VDC solid state electronic relay.
