2-5 Installation & Wiring
Controller Input Wiring
Input Terminals
Hardware inputs can be used to select a program of setpoints or activate groups of
outputs based on sensor signals according to mode logic as described in Section 5.
The 16 inputs on the PS-6144 are arranged on two terminal strips, TB 1 and TB 3, as
shown in Figure 7. Each input is optically isolated and can be powered from an external
DC power source or the Auxiliary Power terminals located on TB 2.
Sinking or Sourcing Each terminal strip TB 1 and TB 3 can be wired to accept sinking or sourcing input
signals, but all eight inputs on that strip will require the same type of signal. Many types
of hardware can drive these inputs, including mechanical switches, relay contacts, DC
3-wire sensors, solid state DC output modules, and PLC DC outputs. 2-wire DC sensors
can also be used, but may require a load resistor in parallel with the input. Typical wiring
diagrams are shown in Figure 7.
Input Functions The following are the input terminals and their corresponding functions:
Program Select (1–8)
The on/off status of these terminals selects which program of setpoints is controlling
the outputs. Binary, BCD, or Gray Code formats can drive these terminals as shown in
Figure 8.
When all program select inputs are off, the “Default” program will become active as
programmed through DEFAULT PROGRAM function.
Group Inputs (9–14)
These inputs work in conjunction with groups of outputs according to mode logic as
discussed in Section 5. Typically, photo eyes and other sensors will operate these inputs.
First Cycle Enable (15)
Mode 5 uses this input to allow the first machine cycle to operate the corresponding
outputs. See Section 5 for details.
Output Enable (16)
Any of the outputs (except analog) can be ANDed with this input through OUTPUT
ENABLE ANDING. Outputs that are ANDed will operate only when this input is on. This
can be used in conjunction with Motion ANDing and output modes.
