The calibrator is equipped with 12 opto-isolated, digital control outputs. These outputs
are activated by the T700‟s user-programmable calibration sequences (see Sections
4.3.1.6 and 4.3.2.8 for instructions on assigning the control inputs to specific calibration
sequences).
These outputs may be used to interface with devices that accept logic-level digital
inputs, such as Programmable Logic Controllers (PLCs), data loggers, or digital
relays/valve drivers.
They are accessed via a 14-pin connector on the calibrator‟s rear panel (see Figure 3-4).

COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Most PLCs have internal provisions for limiting the current the input will
draw. When connecting to a unit that does not have this feature, external
resistors must be used to limit the current through the individual
transistor outputs to ≤50mA (120 Ω for 5V supply).
The pin assignments for the control outputs are:
Closed if the sequence or sequence step activating output is operating
The emitters of the transistors on pins 1 to 12 are bussed together.
